Aesthetic Dermatology

TOPLINE:

Nearly three-quarters of adults with alopecia areata (AA) were not receiving treatment 1 year after diagnosis, according to a retrospective cohort study using data from more than 45,000 individuals.

METHODOLOGY:

• The study population included 45,483 adults aged 18 years and older with new diagnoses of AA between Oct. 15, 2015, and Feb. 28, 2020. Data were from a large U.S. health care database that included medical and pharmacy claims.
• The mean age of the participants was 43.8 years, and 65.7% were female.
• The researchers measured variables that might relate to AA and its treatment patterns within 1 year of starting the study and during the first year of the study, with data collected at 1, 42, 84, and 365 days after study entry.

TAKEAWAYS:

• During the first year after diagnosis, 66.4% of patients received at least one treatment for AA at one or more time points.
• At 1 year, 71.8% of patients were not receiving any active treatment for AA.
• Among those who received treatment, intralesional injections were the most often prescribed therapy (41.8% of patients), followed by topical corticosteroids (40.9%), intramuscular corticosteroids (38.1%), and oral corticosteroids (20.6%).
• Patients diagnosed with either alopecia totalis or alopecia universalis were significantly less likely to receive intralesional steroids and significantly more likely to receive topical corticosteroids than those without these diagnoses (11.1% vs. 44.1% and 25.4% vs. 42.1, respectively).

IN PRACTICE:

The results highlight the need to determine why so many alopecia patients with AA were no longer on treatment after 1 year, although treatment trends may change with the emergence of new therapies, such as JAK inhibitors and others, according to the authors.

SOURCE:

The lead author of the study was Hemin Lee, MD, MPH, Brigham and Women’s Hospital, Boston. The study was published online in JAMA Dermatology.

LIMITATIONS:

The use of insurance claims data did not allow analysis of over-the-counter medications and treatments, and the lack of a single ICD-10 code for defining AA could have resulted in misclassification of outcomes.

DISCLOSURES:

The study received no outside funding, and Dr. Lee had no disclosures. One author had disclosures that included receiving personal fees from Pfizer and Concert outside of the submitted study and participating in alopecia-related trials with Lilly, Concert, Aclaris, and Incyte. Another author’s disclosures included receiving personal fees from companies that included Pfizer, Concert, Lilly, and AbbVie. No other disclosures were reported.

SAN DIEGO – Despite the popularity of fractional lasers cleared for skin rejuvenation in the past decade, fully ablative laser resurfacing is still preferred by some patients because it usually requires only one treatment for reproducible results, according to Arisa E. Ortiz, MD.

Dr. Arisa E. Ortiz

“Fractional resurfacing is great because there is less downtime, but the results are not as dramatic as with fully ablative resurfacing,” Dr. Ortiz, director of laser and cosmetic dermatology at the University of California, San Diego, said at the annual Masters of Aesthetics Symposium. In her practice, she said, “we do a combination,” which can include “fully ablative around the mouth and eyes and fractional everywhere else.”

Key drawbacks to fully ablative laser resurfacing include significant downtime and extensive wound care, “so it’s not for everybody,” she said. Prolonged erythema following treatment is expected, “so patients need to plan for this. It can last 3-4 months, and it will continue to fade and can be covered up with makeup, but it does last a while,” she noted. “One of the things that made ablative resurfacing fall out of favor was the delayed and permanent hypopigmentation where there’s a stark line of demarcation because you can’t treat the neck [with this modality], so patients have this pearly white looking face that appears 6 months after the treatment,” she added.

Preoperatively, Dr. Ortiz asks patients what other cosmetic procedures they have had in the past. For example, if they have had a facelift, they might have neck skin on their jawline, which will react differently to fully ablative resurfacing than facial skin. “I don’t perform fully ablative resurfacing on the neck or body, or in patients with darker skin types,” she said.

To optimize results, she recommends pretreatment of the area with a neuromodulator a week or 2 before the procedure, “so that they’re not actively contracting and recreating creases,” she said. Studies, she noted, have shown that this approach results in better outcomes. She also asks patients to apply a tripeptide serum daily a week or 2 prior to their procedure to stimulate wound healing and collagen remodeling.

For antibiotic and antiviral prophylaxis, Dr. Ortiz typically prescribes doxycycline 100 mg b.i.d. for 7 days and valacyclovir 500 mg b.i.d. for 7 days and asks patients to start the course the night before the procedure. “If they break through the antiviral, I increase to zoster dosing,” she said. “I make sure they have my cell phone number and call me right away if that happens. I don’t routinely prescribe an antifungal, but you can if you want to.”

For anesthesia, Dr. Ortiz applies lidocaine 23%/tetracaine 7% an hour before the procedure and performs nerve blocks at the mentalis, infraorbital, supraorbital, and nasalis muscles. “I also do local infiltration with a three-pronged Mesoram adapter,” she said. “That has changed the comfort level for these patients. I don’t offer any sedation in my practice but that is an option if you have it available. If you’re going to be resurfacing within the orbital rim you need to know how to place corneal shields. Only use injectable lidocaine in this area because if topical lidocaine gets into the eye, it can cause a chemical corneal abrasion. Nothing happens to their vision permanently, but it’s extremely painful for 24-48 hours.”

Dr. Ortiz described postoperative wound care as “the hardest part” of fully ablative laser resurfacing treatments. The treated area will look “bloody and crusty” for 1-2 weeks. She instructs patients to do vinegar soaks four times per day for 2-3 weeks, “depending on how quickly they heal,” she said. She also counsels patients to apply petrolatum ointment to the area and provides them with a bottle of hypochlorous acid spray, an antiseptic – which also helps with the itching they may experience. “They need to avoid the sun, so I recommend full face visors,” she added.

In her clinical experience, postoperative pain medications are not required. “If the patient calls you on day 3 with increased pain, that’s usually a sign of infection; don’t ignore that,” said Dr. Ortiz, who is also president-elect of the American Society for Laser Medicine and Surgery. In a case of suspected infection, she asks the patient to come in right away, and obtains a bacterial culture. “If they break through the doxycycline, it’s usually a gram-negative infection, so I’ll treat them prophylactically for that,” she said.

“Significant itching may be a sign of Candida infection,” she noted. “Because the epidermis has been disrupted, if they have systemic symptoms then you want to consider IV antibiotics because the infection can spread rapidly.”

Dr. Ortiz disclosed having financial relationships with several pharmaceutical and device companies. She is also cochair of the MOAS.

SAN DIEGO – The use of absorbable threads to improve skin laxity is safe and effective, but their long-term aesthetic effects remain unclear, according to Catherine M. DiGiorgio, MD, MS.

In the 1990s, clinicians used nonabsorbable sutures for thread lifts, including polypropylene-barbed threads, which caused adverse events ranging from extrusion and migration to thread expulsion, dimpling, granuloma formation, and prolonged pain, Dr. DiGiorgio, a laser and cosmetic dermatologist who practices in Boston, said at the annual Masters of Aesthetics Symposium. As a result, the Food and Drug Administration withdrew its approval of contour thread aesthetic procedures in 2009. Since then, the development of absorbable threads made from a hybrid of poly-l-lactic acid (PLLA) and polyglycolide/l-lactide (PLGA), and from polydioxanone (PDO) has led to renewed interest in thread lift procedures.

Dr. DiGiorgio

While a surgical facelift remains the gold standard, “we have some options to offer patients for noninvasive tightening,” Dr. DiGiorgio said. “We have devices that provide minimal downtime and are less costly, but results are inconsistent. Thread lifts, or suspension sutures, also have minimal downtime and are less costly, but the [results are] subtle and not long lasting.”

PLGA/PLLA threads consist of an 18% PLGA and 82% PLLA monofilament with bidirectional cones that shift the tissue. They are available in 8, 12, or 16 cones spaced 5-8 mm apart on either side of a 2-cm central cone-free area. “There is a 12-cm, 23-gauge needle on either side of the thread, to allow for insertion,” she explained. “These cones stimulate types I and II collagen, which results in collagenesis. The skin encapsulates the cones, resulting in lasting volume and contour.”

PDO threads, meanwhile, are biodegradable by hydrolysis over 4-8 months. They are inserted with a cannula or a needle and vary based on length, diameter, twined vs. braided, coned vs. barbed, and twisted vs. smooth. “The barbed PDO threads are what I use the most,” Dr. DiGiorgio said. “They provide slight tissue repositioning by anchoring and gripping.”

In 2019, researchers in Korea published results of a study that evaluated the collagen-producing effects of powdered PDO injection, compared with PLLA injection, in a murine model. They found that while both PDO and PLLA induced granulomatous reactions and collagen formation, PDO resulted in slightly more collagen formation than PLLA.

Dr. DiGiorgio, who transitioned to using PDO threads after first using the PLLA/PLGA threads, said that both are effective. “I find PDO threads to be easier. They’re less costly for me, they’re less costly for the patient, and the results are about equivalent.”

Absorbable threads are indicated for the cheek, jawline, neck, lips, forehead, and brow. She finds them most useful “for the lower face, below the nasolabial fold down to the jawline, for improvement of the jowls,” she said. “I don’t think they really work on the neck.”

As with any cosmetic procedure, patient selection is key. According to Dr. DiGiorgio, the patient should have specific and segmental areas of facial laxity amenable to lifting and recontouring along a straight-line vector, adequate dermal thickness, and appropriate expectations for the level of correction. “I like to re-volumize with filler before performing thread lifts to make sure that volume is restored, because you can’t really provide lift to someone with significant volume loss,” she said.
 

Procedural tips

Prior to the procedure, Dr. DiGiorgio marks the area to be treated while the patient is seated upright and holding a mirror. Then, she pulls back the amount of skin laxity the thread is going to correct. The plane of insertion for barbed threads is at the superficial musculoaponeurotic system (SMAS), and she typically uses 3-4 threads on each side of the face.

“How do you know you’re in the right plane?” If the patient is experiencing significant pain, “you’re too deep, and it’s not going to work,” she said. “You can see if the thread is too superficial as you do more of these.”

After the procedure she asks the patient to sit up prior to trimming the threads. “I take a look in the mirror with them and have them smile and make funny faces to see if there is any dimpling or crimpling, which is probably the most common side effect,” she said. “If I see that, I will pull the thread immediately, so we don’t have a problem. It’s a little uncomfortable to pull the thread but not more uncomfortable than the procedure itself, but I think it’s worth doing to avoid having a dimple or a crimple that can last up to a year.”

In her clinical experience, thread lifts last about 8-10 months. “I find that my patients will come in about once a year for this procedure, and the treated area feels tight afterward,” Dr. DiGiorgio said. “I think that sensation of feeling tight also provides satisfaction to the patient. Results are very subtle. It’s tissue repositioning; it is not a facelift. There’s not really any downtime, but further studies are required to see if threads are safe and effective in the long-term.”

In an interview after the meeting, she noted that the learning curve for thread lifts is variable, as with any new procedure a physician chooses to add to his or her practice. “It’s important to see these patients in follow-up 2 weeks after the procedure consistently, especially when someone first starts performing the procedure,” she recommended. “These patients are usually coming in to see me for other treatments, so I see them at regular 3-month intervals regardless. You begin to get a feel for what angles work and why and how to optimize the results. As with any procedure, the more experience you have performing the procedure will result in improved outcomes and improved management.”

Dr. DiGiorgio disclosed that she has been an advisory board member for Quthero and she holds stock options in the company. She is a consultant for Revelle and has received equipment from Acclaro.

As a result, the Food and Drug Administration withdrew its approval of contour thread aesthetic procedures in 2009. Since then, the development of absorbable threads made from a hybrid of poly-l-lactic acid (PLLA) and polyglycolide/l-lactide (PLGA), and from polydioxanone (PDO) has led to renewed interest in thread lift procedures.

Dr. DiGiorgio

While a surgical facelift remains the gold standard, “we have some options to offer patients for noninvasive tightening,” Dr. DiGiorgio said. “We have devices that provide minimal downtime and are less costly, but results are inconsistent. Thread lifts, or suspension sutures, also have minimal downtime and are less costly, but the [results are] subtle and not long lasting.”

PLGA/PLLA threads consist of an 18% PLGA and 82% PLLA monofilament with bidirectional cones that shift the tissue. They are available in 8, 12, or 16 cones spaced 5-8 mm apart on either side of a 2-cm central cone-free area. “There is a 12-cm, 23-gauge needle on either side of the thread, to allow for insertion,” she explained. “These cones stimulate types I and II collagen, which results in collagenesis. The skin encapsulates the cones, resulting in lasting volume and contour.”

PDO threads, meanwhile, are biodegradable by hydrolysis over 4-8 months. They are inserted with a cannula or a needle and vary based on length, diameter, twined vs. braided, coned vs. barbed, and twisted vs. smooth. “The barbed PDO threads are what I use the most,” Dr. DiGiorgio said. “They provide slight tissue repositioning by anchoring and gripping.”

In 2019, researchers in Korea published results of a study that evaluated the collagen-producing effects of powdered PDO injection, compared with PLLA injection, in a murine model. They found that while both PDO and PLLA induced granulomatous reactions and collagen formation, PDO resulted in slightly more collagen formation than PLLA.

Dr. DiGiorgio, who transitioned to using PDO threads after first using the PLLA/PLGA threads, said that both are effective. “I find PDO threads to be easier. They’re less costly for me, they’re less costly for the patient, and the results are about equivalent.”

Absorbable threads are indicated for the cheek, jawline, neck, lips, forehead, and brow. She finds them most useful “for the lower face, below the nasolabial fold down to the jawline, for improvement of the jowls,” she said. “I don’t think they really work on the neck.”

As with any cosmetic procedure, patient selection is key. According to Dr. DiGiorgio, the patient should have specific and segmental areas of facial laxity amenable to lifting and recontouring along a straight-line vector, adequate dermal thickness, and appropriate expectations for the level of correction. “I like to re-volumize with filler before performing thread lifts to make sure that volume is restored, because you can’t really provide lift to someone with significant volume loss,” she said.
 

Procedural tips

Prior to the procedure, Dr. DiGiorgio marks the area to be treated while the patient is seated upright and holding a mirror. Then, she pulls back the amount of skin laxity the thread is going to correct. The plane of insertion for barbed threads is at the superficial musculoaponeurotic system (SMAS), and she typically uses 3-4 threads on each side of the face.

“How do you know you’re in the right plane?” If the patient is experiencing significant pain, “you’re too deep, and it’s not going to work,” she said. “You can see if the thread is too superficial as you do more of these.”

After the procedure she asks the patient to sit up prior to trimming the threads. “I take a look in the mirror with them and have them smile and make funny faces to see if there is any dimpling or crimpling, which is probably the most common side effect,” she said. “If I see that, I will pull the thread immediately, so we don’t have a problem. It’s a little uncomfortable to pull the thread but not more uncomfortable than the procedure itself, but I think it’s worth doing to avoid having a dimple or a crimple that can last up to a year.”

In her clinical experience, thread lifts last about 8-10 months. “I find that my patients will come in about once a year for this procedure, and the treated area feels tight afterward,” Dr. DiGiorgio said. “I think that sensation of feeling tight also provides satisfaction to the patient. Results are very subtle. It’s tissue repositioning; it is not a facelift. There’s not really any downtime, but further studies are required to see if threads are safe and effective in the long-term.”

In an interview after the meeting, she noted that the learning curve for thread lifts is variable, as with any new procedure a physician chooses to add to his or her practice. “It’s important to see these patients in follow-up 2 weeks after the procedure consistently, especially when someone first starts performing the procedure,” she recommended. “These patients are usually coming in to see me for other treatments, so I see them at regular 3-month intervals regardless. You begin to get a feel for what angles work and why and how to optimize the results. As with any procedure, the more experience you have performing the procedure will result in improved outcomes and improved management.”

Dr. DiGiorgio disclosed that she has been an advisory board member for Quthero and she holds stock options in the company. She is a consultant for Revelle and has received equipment from Acclaro.

SAN DIEGO – In the clinical experience of Mathew M. Avram, MD, JD, fractional lasers work best in combination with other devices and wavelengths when treating signs of photoaging, such as dyspigmentation, wrinkles, and actinic damage.

“Using a fractional laser as a solo treatment is missing an opportunity to achieve more dramatic improvement for your patients,” Dr. Avram, director of laser, cosmetics, and dermatologic surgery at Massachusetts General Hospital, Boston, said at the annual Masters of Aesthetics Symposium. Among the laser treatments he performs, “combination fractional treatments, typically using the 1927-nm laser” are associated with the highest patient satisfaction, he said.

The order of device use matters, he noted. First, he recommended, use a pulsed dye laser, KTP, or intense pulsed light (IPL) for erythema and telangiectasias, and/or a Q-switched or picosecond laser for pigment. Second, use an ablative or nonablative fractional laser for resurfacing. “A lot of seborrheic keratoses don’t respond to selective photothermolysis well, so I’ll use liquid nitrogen at the time of treatment and before or after treat with a picosecond laser,” added Dr. Avram. “This combined treatment approach is less painful than ablative fractional treatment. You’re going to have downtime anyway, so why not maximize the results at that one treatment session?”

The fractional 1927 laser delivers hundreds of thousands of microscopic pulses and fosters high water absorption, so it targets superficial skin conditions such as actinic keratoses, lentigines, and ephelides at depths of 200-250 microns. It thermally coagulates 30%-40% of skin, which heals without affecting surrounding skin and leaves no perceptible scar, he said.

Clinicians can also combine devices to treat scars. “For red scars, it’s often best to treat both erythema and scar texture with two lasers at the same session,” Dr. Avram said. Again, the order matters. First, he recommended using the pulse dye laser, IPL, or KTP at low fluence and short pulse duration. Second, treat with an ablative or nonablative fractional laser at a low density. “In my experience the ablative fractional lasers are far more efficacious,” he said. “Then we typically add a little Kenalog and 5-FU via laser-assisted drug delivery.”

Dr. Avram disclosed that he has received consulting fees from Allergan. He also reported holding shareholder interest and intellectual property rights with Cytrellis Biosystems.

SAN DIEGO – Injecting a scar with intralesional steroids is a popular way to reduce its size and soften the surrounding tissue, but proper technique matters, according to Victor Ross, MD.

“A lot of lip service is paid to how to inject the steroid,” Dr. Ross, director of laser and cosmetic dermatology at the Scripps Clinic in San Diego, said at the annual Masters of Aesthetics Symposium. “The most important part is the amount and the fastidiousness that you have injecting. You should see the tip of the needle and be very slow. Use a 1 cc syringe.” He used to inject scars with triamcinolone acetate 40 mg/mL, but now he almost always injects 10-20 mg/mL to avoid inducing white streak-like atrophy or hypopigmentation around the treated area.

“When you treat a scar, you treat the features of the scar that make it stand out,” Dr. Ross continued. “If it’s red, you address the hyperemia. If it’s brown, you address the pigment. You want to have a reasonable pathophysiological basis for what you’re doing. Understand how the scar got there and have a reasonable algorithm.” When he counsels patients about clinical outcomes to expect, he emphasizes rehabilitation instead of blemish-free perfection. “It’s not making the scar go away,” he said. “It’s not restoring completely normal skin form and function; it’s a restorative effort to get toward normality. That’s what it’s all about.”

Besides injecting scars with triamcinolone acetate, other scar treatment options include intralesional 5-fluorouracil, oral antihistamines, COX-2 inhibitors, hydrogel sheeting, compression, acoustic wave therapy, photodynamic therapy, radiofrequency, and lasers. “I’m not a big fan of low-level light; it probably does something [to scars], but I’m skeptical,” Dr. Ross said.

In his clinical opinion, most scars respond best to treatments with ablative and nonablative fractional lasers tuned to gentle settings such as an energy level of 20 millijoules at a density of 5%-10%. “Every scar deserves a chance for laser remediation and rehabilitation,” he said. “With radiation scars you want to be particularly gentle. If you have a Mohs scar that has been subsequently treated with radiation, I would lower my settings by half, because I’ve had some scars worsen with settings for red scars after radiation therapy.”

He often uses fractional lasers for stubborn acne scarring. “The hyperemic component you can treat with a vascular laser, then come back [and treat the scarring] with a nonablative fractional laser, or you could use radiofrequency microneedling as well,” Dr. Ross said.

New or innovative scar treatments coming down the pike, he said, include the following: mitomycin C (applied topically, he said that this has worked well for postoperative keloids), tamoxifen, oral methotrexate, imiquimod (which has mixed results to date), platelet-rich plasma, and retinoids.

Dr. Ross disclosed having research and financial ties to numerous pharmaceutical and device companies.

Recently, my office received several phone calls from patients asking if I perform “trap tox.” Having not been on social media around that time, I assumed the term had something to do with botulinum toxin and the trapezius muscle, but I had never heard it before. Not too long afterwards, patients were asking me about it in the office, using the same terminology, and I had several calls about it in one day. When I asked one trusted patient where she’d heard this term, which seemed to be trending, she told me that she had seen it on Instagram, as an ad or a “suggested for you” post.

Whether it’s a different name or term for a cosmetic procedure or laser we use that I’ve never heard before – such as “lip flip” or trap tox (also known as “Barbie Botox”) – many of these trendy terms spread like wildfire on social media. Some of the terms may be marketing tools started and spread by doctors who perform aesthetic procedures, something I don’t recommend as it only creates confusion for patients and practitioners, similar to the confusion consumers face regarding the plethora of over-the-counter skin care options and the marketing terms used for them. Other terms and trends are also started by nonphysician or non–professionally trained providers, sometimes leading to an unsafe or misleading term for an aesthetic procedure.

Over the past few years, several articles about the impact of social media in aesthetics have been published. In one recent paper, published in 2022, Boen and Jerdan noted that 72% of people in the United States use social media, up from 5% of American adults in 2005. In the United States, they note, “YouTube is the most popular platform with 73% of adult users, followed by Facebook (69%), Instagram (37%), SnapChat (24%), and Twitter (22%). Of the sites used daily, Facebook has the most activity (74%), followed by Instagram (64%), SnapChat (63%), YouTube (51%), and Twitter (42%).” They argue that the pros of social media in aesthetic medicine include its use as an educational tool by medical professionals to educate and provide accurate information about cosmetic procedures, and that “providing factual and evidence-based medical information to the public can help to counteract the abundant misinformation that is out there.” The cons include misinformation, no credentialing verification of the provider of the information – essentially anyone can be an “influencer” – as well as the addictive nature of social media for the consumer.

Along the same lines, younger patients tend to rely more on social media in choosing treatments and providers, further perpetuating any anxiety created from misinformation and unrealistic expectations from nonmedical influencers regarding procedures, filters used on photographs, photo editing, etc., in achieving an aesthetic result.

Physicians, particularly fellowship-trained aesthetic and surgical dermatologists, plastic and reconstructive surgeons, oculoplastic surgeons, and ENT facial plastic surgeons, who have the most training, knowledge, and expertise about aesthetic procedures, often have the least amount of time to devote to education via social media, compared with nonmedical influencers. Unless sponsored, they are also not being compensated for using it as an educational tool, except for potential indirect compensation from using it as a marketing tool for themselves and their practices. In contrast, nonmedical influencers often have many followers and time to create content, and in some cases, this is their full-time job.

All in all, most authors agree that social media has been associated with an increased acceptance of cosmetic surgery and procedures. Whether it be a trend seen on social media, or viewing one’s appearance in a filtered or photoediting app, or seeing an image of how another person looks (similar to how people in magazines, films and on television, were viewed in the past), social media has piqued people’s interest in aesthetics. It remains a balance for interested physicians to help keep information about cosmetic procedures presented in a healthy, interesting, professional, and accurate manner, and in a non–time-consuming way.

This question was posed by Ousmane Faye, MD, PhD, director general of Mali’s Bamako Dermatology Hospital, at the World Congress of Dermatology. 

Dr. Faye explored the issue during a hot topics session at the meeting, prefacing that it was an important question to ask because “in West Africa, skin bleaching is very common.”

“There are many local names” for skin bleaching, he said. “For example, in Senegal, it’s called xessal; in Mali and Ivory Coast, its name is caco; in South Africa, there are many names, like ukutsheyisa.”

Skin bleaching refers to the cosmetic misuse of topical agents to change one’s natural skin color. It’s a centuries-old practice that people, mainly women, adopt “to increase attractiveness and self-esteem,” explained Dr. Faye.

To demonstrate how pervasive skin bleaching is on the continent, he presented a slide that summarized figures from six studies spanning the past 2 decades. Prevalence ranged from 25% in Mali (based on a 1993 survey of 210 women) to a high of 79.25% in Benin (from a sample size of 511 women in 2019). In other studies of women in Burkina Faso and Togo, the figures were 44.3% and 58.9%, respectively. The most recently conducted study, which involved 2,689 Senegalese women and was published in 2022, found that nearly 6 in 10 (59.2%) respondents used skin-lightening products.

But skin bleaching isn’t just limited to Africa, said session moderator Omar Lupi, MD, PhD, associate professor of dermatology at the Federal University of the State of Rio de Janeiro, when approached for an independent comment. “It’s a traditional practice around the world. Maybe not in the developed countries, but it’s quite common in Africa, in South America, and in Asia.”

His sentiments are echoed in a meta-analysis that was published in the International Journal of Dermatology in 2019. The work examined 68 studies involving more than 67,000 people across Africa, Asia, Europe, the Middle East, and North America. It found that the pooled lifetime prevalence of skin bleaching was 27.7% (95% confidence interval, 19.6-37.5; P < .01).

“This is an important and interesting topic because our world is shrinking,” Dr. Lupi told this news organization. “Even in countries that don’t have bleaching as a common situation, we now have patients who are migrating from one part [of the world] to another, so bleaching is something that can knock on your door and you need to be prepared.”

Misuse leads to complications

The issue is pertinent to dermatologists because skin bleaching is associated with a wide range of complications. Take, for example, topical steroids, which are the most common products used for bleaching, said Dr. Faye in his talk. 

“Clobetasol can suppress the hypothalamic-pituitary-adrenal (HPA) function,” he said, referring to the body’s main stress response system. “It can also foster skin infection, including bacterial, fungal, viral, and parasitic infection.”

In addition, topical steroids that are misused as skin lighteners have been reported to cause stretch marks, skin atrophy, inflammatory acne, and even metabolic disorders such as diabetes and hypertension, said Dr. Faye.

To further his point, he cited a 2021 prospective case-control study conducted across five sub-Saharan countries, which found that the use of “voluntary cosmetic depigmentation” significantly increased a person’s risk for necrotizing fasciitis of the lower limbs (odds ratio, 2.29; 95% CI, 1.19-3.73; P = .0226).

Similarly, mercury, another substance found in products commonly used to bleach skin, has been associated with problems ranging from rashes to renal toxicity. And because it’s so incredibly harmful, mercury is also known to cause neurologic abnormalities. 

Apart from causing certain conditions, prolonged use of skin-lightening products can change the way existing diseases present themselves as well as their severity, added Dr. Faye. 
 

An increased risk

But what about skin bleaching’s link with cancer? “Skin cancer on Black skin is uncommon, yet it occurs in skin-bleaching women,” said Dr. Faye.

“Since 2000, we have had some cases of skin cancer associated with skin bleaching,” he continued, adding that squamous cell carcinoma (SCC) is the most frequent type of cancer observed. 

If you look at what’s been published on the topic so far, you’ll see that “all the cases of skin cancer are located over the neck or some exposed area when skin bleaching products are used for more than 10 years,” said Dr. Faye. “And most of the time, the age of the patient ranges from 30 to 60 years.”

The first known case in Africa was reported in a 58-year-old woman from Ghana, who had been using skin bleaching products for close to 30 years. The patient presented with tumors on her face, neck, and arms.

Dr. Faye then proceeded to share more than 10 such carcinoma cases. “These previous reports strongly suggest a relationship between skin bleaching and skin cancers,” said Dr. Faye.

Indeed, there have been reports and publications in the literature that support his observation, including one last year, which found that use of the tyrosinase inhibitor hydroquinone was associated with approximately a threefold increased risk for skin cancer.

For some, including Brazil’s Dr. Lupi, Dr. Faye’s talk was enlightening: “I didn’t know about this relationship [of bleaching] with skin cancer, it was something new for me.”

But the prevalence of SCC is very low, compared with that of skin bleaching, Dr. Faye acknowledged. Moreover, the cancer observed in the cases reported could have resulted from a number of reasons, including exposure to harmful ultraviolet rays from the sun and genetic predisposition in addition to the use of bleaching products such as hydroquinone. “Other causes of skin cancer are not excluded,” he said.

To further explore the link between skin bleaching and cancer, “we need case-control studies to provide more evidence,” he added. Until then, dermatologists “should keep on promoting messages” to prevent SCC from occurring. This includes encouraging the use of proper sun protection in addition to discouraging the practice of skin bleaching, which still persists despite more than 10 African nations banning the use of toxic skin-lightening products.

Dr. Faye and Dr. Lupi report no relevant financial relationships.

Almonds and almond oil are known to exhibit anti-inflammatory, antihepatotoxicity, and immunity-boosting activity.¹ The seed from the deciduous almond tree (Oleum amygdalae), which is native to Iran and parts of the Levant, almonds contain copious amounts of phenols and polyphenols, fatty acids, and vitamin E, all of which are known to exert antioxidant activity.^2-5 These seeds have been found to have a substantial impact on serum lipids.⁴ Emollient and sclerosant characteristics have also been linked to almond oil, which has been found to ameliorate complexion and skin tone.⁵ Significantly, in vitro and in vivo studies have shown that UVB-induced photoaging can be attenuated through the use of almond oil and almond skin extract.² Further, in traditional Chinese Medicine, Ayurveda, and ancient Greco-Persian medicine, almond oil was used to treat cutaneous conditions, including eczema and psoriasis.¹The focus of this column is to provide an update on the use of almonds and almond oil for skincare since covering the topic in July 2014.

Antiphotoaging activity

In 2019, Foolad and Vaughn conducted a prospective, investigator-blind, randomized controlled trial to determine the effects of almond consumption on facial sebum production and wrinkles. Participants (28 postmenopausal women with Fitzpatrick skin types I and II completed the study) consumed 20% of their daily energy intake in almonds or a calorie-matched snack over 16 weeks through the UC Davis Dermatology Clinic. Photographic analysis revealed that the almond group experienced significantly diminished wrinkle severity, compared with the control group. The investigators concluded that daily almond consumption has the potential to decrease wrinkle severity in postmenopausal women and that almonds may confer natural antiaging effects.⁴

In a similar investigation 2 years later, Rybak et al. reported on a prospective, randomized controlled study to ascertain the effects of almond consumption on photoaging in postmenopausal women with Fitzpatrick skin types I or II who obtained 20% of their daily energy consumption via almonds or a calorie-matched snack for 24 weeks. Results demonstrated significant effects conferred by almond consumption, with average wrinkle severity substantially diminished in the almond group at weeks 16 (by 15%) and 24 (by 16%), compared with baseline. In addition, facial pigment intensity was reduced by 20% in the almond group by week 16 and this was maintained through the end of the study. Further, sebum excretion was higher in the control group. The investigators concluded that the daily consumption of almonds may have the potential to enhance protection against photoaging, particularly in terms of facial wrinkles and pigment intensity, in postmenopausal women.³

Later in 2021, Li et al. conducted a study in 39 healthy Asian women (18-45 years old) with Fitzpatrick skin types II to IV to investigate the effects of almond consumption on UVB resistance. The researchers randomized participants to eat either 1.5 oz of almonds or 1.8 oz of pretzels daily for 12 weeks. Results showed that the minimal erythema dose was higher in the almond group as compared with the control group. No differences were observed in hydration, melanin, roughness, or sebum on facial skin. The authors concluded that daily oral almond intake may improve photoprotection by raising the minimal erythema dose.²

In a 2022 review on the cutaneous benefits of sweet almond, evening primrose, and jojoba oils, Blaak and Staib noted that all three have been used for hundreds if not thousands of years in traditional medicine to treat various conditions, including skin disorders. Further, they concluded that the longstanding uses of these oils has been borne out by contemporary data, which reveal cutaneous benefits for adult and young skin, particularly in bolstering stratum corneum integrity, recovery, and lipid ratio.⁶

Later that year, Sanju et al., reporting on the development and assessment of a broad-spectrum polyherbal sunscreen delivered through solid lipid nanoparticles, noted that almond oil was among the natural ingredients used because of its photoprotective characteristics. Overall, the sunscreen formulation, Safranal, was found to impart robust protection against UV radiation.⁷

Wound healing

In 2020, Borzou et al. conducted a single-blind randomized clinical trial to ascertain the impact of topical almond oil in preventing pressure injuries. Data collection occurred over 8 months in a hospital setting, with 108 patients randomly assigned to receive almond oil, placebo (liquid paraffin), or the control (standard of care). The researchers found that topically applied almond oil was linked to a lower incidence of pressure injuries, and they arose later in the study as compared with those injuries in the groups receiving paraffin or standard of care. Pressure injury incidence was 5.6% in the almond oil group, 13.9% in the placebo group, and 25.1% in the control group.⁸

That same year, Caglar et al. completed a randomized controlled trial in 90 preterm infants to assess the effects of sunflower seed oil and almond oil on the stratum corneum. Infants were randomly selected for treatment with either oil or control. A nurse researcher applied oils to the whole body except for the head and face four times daily for 5 days. Investigators determined that stratum corneum hydration was better in the oil groups as compared with control, with no difference found between sunflower seed and almond oils.⁹

Eczema, hand dermatitis, and striae

In 2018, Simon et al. performed a randomized, double-blind study to determine the short- and long-term effects of two emollients on pruritus and skin restoration in xerotic eczema. The emollients contained lactic acid and refined almond oil, with one also including polidocanol. Both emollients were effective in reducing the severity of itching, with skin moisture and lipid content found to have risen after the initial administration and yielding steady improvement over 2 weeks.¹⁰

Earlier that year, Zeichner et al. found that the use of an OTC sweet almond oil, rich in fatty acids and a standard-bearing treatment for eczema and psoriasis for centuries, was effective in treating hand dermatitis. Specifically, the moisturizer, which contained 7% sweet almond oil and 2% colloidal oatmeal, was identified as safe and effective in resolving moderate to severe hand dermatitis.¹¹

Some studies have also shown almond oil to be effective against striae gravidarum. Hajhashemi et al. conducted a double-blind clinical trial in 160 nulliparous women to compare the effects of aloe vera gel and sweet almond oil on striae gravidarum in 2018. Volunteers were randomly assigned to one of three case groups (Aloe vera, sweet almond oil, or base cream) who received topical treatment on the abdomen, or the fourth group, which received no treatment. Results showed that both treatment creams were effective in decreasing erythema and the pruritus associated with striae as well as in preventing their expansion.¹² Previously, Tashan and Kafkasli showed in a nonrandomized study that massage with bitter almond oil may diminish the visibility of present striae gravidarum and prevent the emergence of new striae.¹³

Conclusion

Almonds and almond oil have been used as food and in traditional medical practices dating back several centuries. In the last decade, intriguing results have emerged regarding the effects of almond consumption or topical almond oil administration on skin health. While much more research is necessary, the recent data seem to support the traditional uses of this tree seed for dermatologic purposes.

Earlier that year, Zeichner et al. found that the use of an OTC sweet almond oil, rich in fatty acids and a standard-bearing treatment for eczema and psoriasis for centuries, was effective in treating hand dermatitis. Specifically, the moisturizer, which contained 7% sweet almond oil and 2% colloidal oatmeal, was identified as safe and effective in resolving moderate to severe hand dermatitis.¹¹

Some studies have also shown almond oil to be effective against striae gravidarum. Hajhashemi et al. conducted a double-blind clinical trial in 160 nulliparous women to compare the effects of aloe vera gel and sweet almond oil on striae gravidarum in 2018. Volunteers were randomly assigned to one of three case groups (Aloe vera, sweet almond oil, or base cream) who received topical treatment on the abdomen, or the fourth group, which received no treatment. Results showed that both treatment creams were effective in decreasing erythema and the pruritus associated with striae as well as in preventing their expansion.¹² Previously, Tashan and Kafkasli showed in a nonrandomized study that massage with bitter almond oil may diminish the visibility of present striae gravidarum and prevent the emergence of new striae.¹³

Conclusion

Almonds and almond oil have been used as food and in traditional medical practices dating back several centuries. In the last decade, intriguing results have emerged regarding the effects of almond consumption or topical almond oil administration on skin health. While much more research is necessary, the recent data seem to support the traditional uses of this tree seed for dermatologic purposes.

Almonds and almond oil are known to exhibit anti-inflammatory, antihepatotoxicity, and immunity-boosting activity.¹ The seed from the deciduous almond tree (Oleum amygdalae), which is native to Iran and parts of the Levant, almonds contain copious amounts of phenols and polyphenols, fatty acids, and vitamin E, all of which are known to exert antioxidant activity.^2-5 These seeds have been found to have a substantial impact on serum lipids.⁴ Emollient and sclerosant characteristics have also been linked to almond oil, which has been found to ameliorate complexion and skin tone.⁵ Significantly, in vitro and in vivo studies have shown that UVB-induced photoaging can be attenuated through the use of almond oil and almond skin extract.² Further, in traditional Chinese Medicine, Ayurveda, and ancient Greco-Persian medicine, almond oil was used to treat cutaneous conditions, including eczema and psoriasis.¹The focus of this column is to provide an update on the use of almonds and almond oil for skincare since covering the topic in July 2014.

Antiphotoaging activity

In 2019, Foolad and Vaughn conducted a prospective, investigator-blind, randomized controlled trial to determine the effects of almond consumption on facial sebum production and wrinkles. Participants (28 postmenopausal women with Fitzpatrick skin types I and II completed the study) consumed 20% of their daily energy intake in almonds or a calorie-matched snack over 16 weeks through the UC Davis Dermatology Clinic. Photographic analysis revealed that the almond group experienced significantly diminished wrinkle severity, compared with the control group. The investigators concluded that daily almond consumption has the potential to decrease wrinkle severity in postmenopausal women and that almonds may confer natural antiaging effects.⁴

In a similar investigation 2 years later, Rybak et al. reported on a prospective, randomized controlled study to ascertain the effects of almond consumption on photoaging in postmenopausal women with Fitzpatrick skin types I or II who obtained 20% of their daily energy consumption via almonds or a calorie-matched snack for 24 weeks. Results demonstrated significant effects conferred by almond consumption, with average wrinkle severity substantially diminished in the almond group at weeks 16 (by 15%) and 24 (by 16%), compared with baseline. In addition, facial pigment intensity was reduced by 20% in the almond group by week 16 and this was maintained through the end of the study. Further, sebum excretion was higher in the control group. The investigators concluded that the daily consumption of almonds may have the potential to enhance protection against photoaging, particularly in terms of facial wrinkles and pigment intensity, in postmenopausal women.³

Later in 2021, Li et al. conducted a study in 39 healthy Asian women (18-45 years old) with Fitzpatrick skin types II to IV to investigate the effects of almond consumption on UVB resistance. The researchers randomized participants to eat either 1.5 oz of almonds or 1.8 oz of pretzels daily for 12 weeks. Results showed that the minimal erythema dose was higher in the almond group as compared with the control group. No differences were observed in hydration, melanin, roughness, or sebum on facial skin. The authors concluded that daily oral almond intake may improve photoprotection by raising the minimal erythema dose.²

In a 2022 review on the cutaneous benefits of sweet almond, evening primrose, and jojoba oils, Blaak and Staib noted that all three have been used for hundreds if not thousands of years in traditional medicine to treat various conditions, including skin disorders. Further, they concluded that the longstanding uses of these oils has been borne out by contemporary data, which reveal cutaneous benefits for adult and young skin, particularly in bolstering stratum corneum integrity, recovery, and lipid ratio.⁶

Later that year, Sanju et al., reporting on the development and assessment of a broad-spectrum polyherbal sunscreen delivered through solid lipid nanoparticles, noted that almond oil was among the natural ingredients used because of its photoprotective characteristics. Overall, the sunscreen formulation, Safranal, was found to impart robust protection against UV radiation.⁷

Wound healing

In 2020, Borzou et al. conducted a single-blind randomized clinical trial to ascertain the impact of topical almond oil in preventing pressure injuries. Data collection occurred over 8 months in a hospital setting, with 108 patients randomly assigned to receive almond oil, placebo (liquid paraffin), or the control (standard of care). The researchers found that topically applied almond oil was linked to a lower incidence of pressure injuries, and they arose later in the study as compared with those injuries in the groups receiving paraffin or standard of care. Pressure injury incidence was 5.6% in the almond oil group, 13.9% in the placebo group, and 25.1% in the control group.⁸

That same year, Caglar et al. completed a randomized controlled trial in 90 preterm infants to assess the effects of sunflower seed oil and almond oil on the stratum corneum. Infants were randomly selected for treatment with either oil or control. A nurse researcher applied oils to the whole body except for the head and face four times daily for 5 days. Investigators determined that stratum corneum hydration was better in the oil groups as compared with control, with no difference found between sunflower seed and almond oils.⁹

Eczema, hand dermatitis, and striae

In 2018, Simon et al. performed a randomized, double-blind study to determine the short- and long-term effects of two emollients on pruritus and skin restoration in xerotic eczema. The emollients contained lactic acid and refined almond oil, with one also including polidocanol. Both emollients were effective in reducing the severity of itching, with skin moisture and lipid content found to have risen after the initial administration and yielding steady improvement over 2 weeks.¹⁰

Earlier that year, Zeichner et al. found that the use of an OTC sweet almond oil, rich in fatty acids and a standard-bearing treatment for eczema and psoriasis for centuries, was effective in treating hand dermatitis. Specifically, the moisturizer, which contained 7% sweet almond oil and 2% colloidal oatmeal, was identified as safe and effective in resolving moderate to severe hand dermatitis.¹¹

Some studies have also shown almond oil to be effective against striae gravidarum. Hajhashemi et al. conducted a double-blind clinical trial in 160 nulliparous women to compare the effects of aloe vera gel and sweet almond oil on striae gravidarum in 2018. Volunteers were randomly assigned to one of three case groups (Aloe vera, sweet almond oil, or base cream) who received topical treatment on the abdomen, or the fourth group, which received no treatment. Results showed that both treatment creams were effective in decreasing erythema and the pruritus associated with striae as well as in preventing their expansion.¹² Previously, Tashan and Kafkasli showed in a nonrandomized study that massage with bitter almond oil may diminish the visibility of present striae gravidarum and prevent the emergence of new striae.¹³

SAN DIEGO – Emerging research on so-called “clock genes” suggests that the human skin has different daytime and nighttime needs, according to Ava Shamban, MD.

“Paying attention to the circadian rhythm of the skin is every bit as important as moisturizing the skin,” Dr. Shamban, a dermatologist who practices in Santa Monica, Calif., said at the annual Masters of Aesthetics Symposium. “It is paramount to both your morning and evening skin regimen routine,” she added.

Circadian rhythms are physical, mental, and behavioral changes that follow a 24-hour cycle. “These natural processes respond primarily to light and dark and affect most living things, including animals, plants, and microbes,” she said. “The circadian system is composed of peripheral circadian oscillators in many other cells, including the skin.”

The science has been around awhile, but dermatologists didn’t understand its impact until recently, she said.

In 1729, the French astronomer Jean-Jacques d’Ortous de Mairan demonstrated that mimosa leaves, which open at dawn and close at dusk, continued this cycle even when kept in darkness. In the 1970s, Seymour Benzer and Ronald Konopka showed that mutations in an unknown gene disrupted the circadian clock of fruit flies.

And in 2017, the Nobel Prize in Physiology or Medicine was awarded to Jeffrey C. Hall, Michael Rosbash, and Michael W. Young for discovering molecular mechanisms that control circadian rhythm. Using fruit flies as a model, they isolated a gene that controls the normal daily biological rhythm.

“They showed that this gene encodes a protein that accumulates in the cell during the night and is then degraded during the day, and they identified additional protein components, exposing the mechanism governing the self-sustaining clockwork inside the cell,” said Dr. Shamban.

In humans and other mammals, the primary body clock is located in the suprachiasmatic nucleus, a cluster of approximately 10,000 neurons located on either side of the midline above the optic chiasma, about 3 cm behind the eyes. Several clock genes have been identified that regulate and control transcription and translation.

“Expression of these core clock genes inside the cell influences many signaling pathways, which allows the cells to identify the time of day and perform their appropriate function,” Dr. Shamban said. “Furthermore, phosphorylation of core clock proteins leads to degradation to keep the 24-hour cycle in sync.”

Photoreceptive molecules known as opsins also appear to play a role in regulating the skin’s clock. A systematic review of 22 articles published in 2020 found that opsins are present in keratinocytes, melanocytes, dermal fibroblasts, and hair follicle cells, and they have been shown to mediate wound healing, melanogenesis, hair growth, and skin photoaging in human and nonhuman species.

“You may wonder, why does the skin respond so nicely to light?” Dr. Shamban said. “Because it contains opsins, and light exposure through opsin-regulated pathways stimulates melanin production.”

Patients can support their skin’s clock genes by understanding that skin barrier functions such as photoprotection and sebum production are increased during the day, while skin permeability processes such as DNA repair, cell proliferation, and blood flow are enhanced at night.

“Your skin has different daytime and nighttime needs,” Dr. Shamban commented. “Simply put, daytime is defense, and nighttime is offense. I think we’ve known this intuitively, but to know that there is science supporting this idea is important.”

Dr. Shamban wrote the book “Heal Your Skin: The Breakthrough Plan for Renewal” (Wiley, 2011). She disclosed that she conducts clinical trials for many pharmaceutical and device companies.

SAN DIEGO –After fashion model Linda Evangelista filed and ultimately settled a lawsuit against Zeltiq Aesthetics in 2022 subsequent to developing paradoxical adipose hyperplasia she claimed was caused by several sessions of CoolSculpting, some aesthetic experts wondered how consumers would embrace the fat reduction procedure going forward.

The negative publicity surrounding this case “is thought to have detracted from some of the volume of it [in terms of demand], but it looks like it’s coming back again,” Omar A. Ibrahimi, MD, PhD, medical director of the Connecticut Skin Institute, Stamford, said during a presentation on noninvasive fat removal treatment options at the annual Masters of Aesthetics Symposium.

In fact, he said, CoolSculpting accounts for an estimated 72% of noninvasive fat removal treatments performed in the United States. “By and large, there is high satisfaction with this procedure,” said Dr. Ibrahimi. “There have been about 17 million procedures done worldwide. Paradoxical adipose hyperplasia is a very rare side effect. As newer iterations of this technology have come out, I think there is an even lower incidence.”

CoolSculpting, or cryolipolysis, freezes excess fat to remove it from stubborn areas via panniculitis. The technology was developed by Dieter Manstein MD, PhD, and R. Rox Anderson, MD, at Massachusetts General Hospital and Harvard Medical School, both in Boston, and cleared by the U.S. Food and Drug Administration for noninvasive fat removal in 2010.

“If you kill a fat cell in an adult, it can’t come back,” Dr. Ibrahimi said. “When this technology first came out it was very simple. We treated an area once and were done. Now we know to treat the area multiple times, and you can treat a much larger volume in a patient during one session safely. You can bring about dramatic results, but it often takes a series of 35-minute treatment cycles and about 3 months to see clinical results. There are published studies showing that results are persisting even 10 years after treatment. This is nice, because I tell my patients, ‘if you keep up with your diet and exercise, we don’t expect the fat to come back.’ ”

Other noninvasive options for fat removal include the following:

• Ultrasound. Options include high-intensity focused ultrasound (Liposonix) and pulsed focused ultrasound (UltraShape). Dr. Ibrahimi described these devices as “very painful, and the results were very difficult to reproduce from the initial clinical studies.”
• Low-level light therapy. Early devices on the market include Zerona and UltraSlim. “Oftentimes these lacked any sort of histological analysis,” he said. “There was no obvious mechanism of action, and questionable efficacy.”
• Laser. Powered by a 1060-nm laser, SculpSure can reduce fat cells safely in 25-minute treatment sessions, Dr. Ibrahimi said. Each session is delivered with one of four available applicators and involves 4 minutes of heating and the next 21 minutes alternating between heating and cooling. “You’re trying to reach a target temperature that kills fat cells,” he explained. “The beauty of having these applicators is that you can kind of customize to the individual patient; it uses contact cooling, and it’s safe for all Fitzpatrick skin types. This device results in a 10%-12% reduction in fat, so it’s clinically significant but very modest.”

A robotic version of the technology, known as the Robotic Fat Killer, is also available. So is the EON, a touchless 1064-nm laser FDA cleared for abdominal, flank, thigh, and back fat reduction. “It adapts to the body shape of the area and individual to deliver a customized treatment,” Dr. Ibrahimi said.

• Radiofrequency. Most devices on the market, such as truSculpt and Vanquish, are powered by monopolar radiofrequency (RF) energy. “Similar to the 1060-nm laser, you can customize these treatments,” he said. “You’re treating to a target temperature. It involves 15-minute cycles, and there are clinical, histology, and ultrasound data supporting this technology.”

Dr. Ibrahimi uses truSculpt and CoolSculpting in his practice, “but sometimes you have patients who are ‘too fit’ for CoolSculpting; they don’t fit the handpiece perfectly,” he said. “That’s where having a monopolar RF or a 1060-nm laser is useful, to help you hone in on those stubborn pockets of fat.”

• Deoxycholic acid. While not a device, deoxycholic acid (Kybella), administered subcutaneously, is approved by the FDA for improving “the appearance of moderate to severe convexity or fullness associated with submental fat” in adults. “A lot of people use it off-label on the abdomen and other stubborn areas,” Dr. Ibrahimi said. “It often requires a series of treatments. That’s the biggest limiting issue with using this technology. It works well, but compared to CoolSculpting, there is a lot of swelling and bruising, which you would expect with an injectable. Managing that down time and hand holding is difficult. But if you can get patients to buy into the downtime, [it yields] pretty impressive results.”

Dr. Ibrahimi also discussed the promise of electrical muscle stimulation for strengthening, firming, and toning muscles. The technology applies an electrical current through electrodes placed on the skin, which stimulates muscles, or through an electromagnetic field.

In a published study of 45 men and women, Dr. Ibrahimi, Anne Chapas, MD, medical director of UnionDerm in New York, and colleagues evaluated the safety and efficacy of an electrical muscle stimulation system for improving muscle strength and toning of the upper extremities.

For the treatments, they used disposable contact pads to place pairs of electrodes on the biceps and on the triceps. All patients (median age 42) received 30-minute treatments twice weekly for 2 or 3 weeks, corresponding to four or six total sessions respectively, depending on the study site. Follow-ups were conducted 30 and 90 days after treatment. They used a validated dynamometer device to measure strength at baseline, at the final treatment session, and at the post-treatment 30- and 90-day visits.

“We saw about a 40% increase in strength in the biceps and about a 30% increase in strength in the triceps,” Dr. Ibrahimi said. “Interestingly, the effect got greater at 30 and 90 days, so this is something that lingers on for quite a while.” In addition to the increase in strength, the researchers and patients noted an improvement in the appearance of the arms. He predicted that this technology “is going to play a role in functional medicine and getting injured athletes back to their sports faster.”

Dr. Ibrahimi disclosed that he is a member of the Advisory Board for Accure Acne, AbbVie, Cutera (manufacturer of truSculpt), Lutronic, Blueberry Therapeutics, Cytrellis, and Quthero. He also holds stock in many device and pharmaceutical companies (none are relevant to the treatments mentioned in this story).

It involves 15-minute cycles, and there are clinical, histology, and ultrasound data supporting this technology.”

Dr. Ibrahimi uses truSculpt and CoolSculpting in his practice, “but sometimes you have patients who are ‘too fit’ for CoolSculpting; they don’t fit the handpiece perfectly,” he said. “That’s where having a monopolar RF or a 1060-nm laser is useful, to help you hone in on those stubborn pockets of fat.”

• Deoxycholic acid. While not a device, deoxycholic acid (Kybella), administered subcutaneously, is approved by the FDA for improving “the appearance of moderate to severe convexity or fullness associated with submental fat” in adults. “A lot of people use it off-label on the abdomen and other stubborn areas,” Dr. Ibrahimi said. “It often requires a series of treatments. That’s the biggest limiting issue with using this technology. It works well, but compared to CoolSculpting, there is a lot of swelling and bruising, which you would expect with an injectable. Managing that down time and hand holding is difficult. But if you can get patients to buy into the downtime, [it yields] pretty impressive results.”

Dr. Ibrahimi also discussed the promise of electrical muscle stimulation for strengthening, firming, and toning muscles. The technology applies an electrical current through electrodes placed on the skin, which stimulates muscles, or through an electromagnetic field.

In a published study of 45 men and women, Dr. Ibrahimi, Anne Chapas, MD, medical director of UnionDerm in New York, and colleagues evaluated the safety and efficacy of an electrical muscle stimulation system for improving muscle strength and toning of the upper extremities.

For the treatments, they used disposable contact pads to place pairs of electrodes on the biceps and on the triceps. All patients (median age 42) received 30-minute treatments twice weekly for 2 or 3 weeks, corresponding to four or six total sessions respectively, depending on the study site. Follow-ups were conducted 30 and 90 days after treatment. They used a validated dynamometer device to measure strength at baseline, at the final treatment session, and at the post-treatment 30- and 90-day visits.

“We saw about a 40% increase in strength in the biceps and about a 30% increase in strength in the triceps,” Dr. Ibrahimi said. “Interestingly, the effect got greater at 30 and 90 days, so this is something that lingers on for quite a while.” In addition to the increase in strength, the researchers and patients noted an improvement in the appearance of the arms. He predicted that this technology “is going to play a role in functional medicine and getting injured athletes back to their sports faster.”

Dr. Ibrahimi disclosed that he is a member of the Advisory Board for Accure Acne, AbbVie, Cutera (manufacturer of truSculpt), Lutronic, Blueberry Therapeutics, Cytrellis, and Quthero. He also holds stock in many device and pharmaceutical companies (none are relevant to the treatments mentioned in this story).

SAN DIEGO –After fashion model Linda Evangelista filed and ultimately settled a lawsuit against Zeltiq Aesthetics in 2022 subsequent to developing paradoxical adipose hyperplasia she claimed was caused by several sessions of CoolSculpting, some aesthetic experts wondered how consumers would embrace the fat reduction procedure going forward.

The negative publicity surrounding this case “is thought to have detracted from some of the volume of it [in terms of demand], but it looks like it’s coming back again,” Omar A. Ibrahimi, MD, PhD, medical director of the Connecticut Skin Institute, Stamford, said during a presentation on noninvasive fat removal treatment options at the annual Masters of Aesthetics Symposium.

In fact, he said, CoolSculpting accounts for an estimated 72% of noninvasive fat removal treatments performed in the United States. “By and large, there is high satisfaction with this procedure,” said Dr. Ibrahimi. “There have been about 17 million procedures done worldwide. Paradoxical adipose hyperplasia is a very rare side effect. As newer iterations of this technology have come out, I think there is an even lower incidence.”

CoolSculpting, or cryolipolysis, freezes excess fat to remove it from stubborn areas via panniculitis. The technology was developed by Dieter Manstein MD, PhD, and R. Rox Anderson, MD, at Massachusetts General Hospital and Harvard Medical School, both in Boston, and cleared by the U.S. Food and Drug Administration for noninvasive fat removal in 2010.

“If you kill a fat cell in an adult, it can’t come back,” Dr. Ibrahimi said. “When this technology first came out it was very simple. We treated an area once and were done. Now we know to treat the area multiple times, and you can treat a much larger volume in a patient during one session safely. You can bring about dramatic results, but it often takes a series of 35-minute treatment cycles and about 3 months to see clinical results. There are published studies showing that results are persisting even 10 years after treatment. This is nice, because I tell my patients, ‘if you keep up with your diet and exercise, we don’t expect the fat to come back.’ ”

Other noninvasive options for fat removal include the following:

• Ultrasound. Options include high-intensity focused ultrasound (Liposonix) and pulsed focused ultrasound (UltraShape). Dr. Ibrahimi described these devices as “very painful, and the results were very difficult to reproduce from the initial clinical studies.”
• Low-level light therapy. Early devices on the market include Zerona and UltraSlim. “Oftentimes these lacked any sort of histological analysis,” he said. “There was no obvious mechanism of action, and questionable efficacy.”
• Laser. Powered by a 1060-nm laser, SculpSure can reduce fat cells safely in 25-minute treatment sessions, Dr. Ibrahimi said. Each session is delivered with one of four available applicators and involves 4 minutes of heating and the next 21 minutes alternating between heating and cooling. “You’re trying to reach a target temperature that kills fat cells,” he explained. “The beauty of having these applicators is that you can kind of customize to the individual patient; it uses contact cooling, and it’s safe for all Fitzpatrick skin types. This device results in a 10%-12% reduction in fat, so it’s clinically significant but very modest.”

A robotic version of the technology, known as the Robotic Fat Killer, is also available. So is the EON, a touchless 1064-nm laser FDA cleared for abdominal, flank, thigh, and back fat reduction. “It adapts to the body shape of the area and individual to deliver a customized treatment,” Dr. Ibrahimi said.

• Radiofrequency. Most devices on the market, such as truSculpt and Vanquish, are powered by monopolar radiofrequency (RF) energy. “Similar to the 1060-nm laser, you can customize these treatments,” he said. “You’re treating to a target temperature.
