A member of the Elaeagnaceae family, Hippophae rhamnoides, better known as sea buckthorn, is a high-altitude wild shrub endemic to Europe and Asia with edible fruits and a lengthy record of use in traditional Chinese medicine.1-6 Used as a health supplement and consumed in the diet throughout the world,5 sea buckthorn berries, seeds, and leaves have been used in traditional medicine to treat burns/injuries, edema, hypertension, inflammation, skin grafts, ulcers, and wounds.4,7

This hardy plant is associated with a wide range of biologic activities, including anti-atherogenic, anti-atopic dermatitis, antibacterial, anticancer, antifungal, anti-inflammatory, antimicrobial, antioxidant, anti-psoriasis, anti-sebum, anti-stress, anti-tumor, cytoprotective, hepatoprotective, immunomodulatory, neuroprotective, radioprotective, and tissue regenerative functions.4,5,8-11Sea buckthorn has also been included in several cosmeceutical formulations to treat wrinkles, scars, pigmentary conditions, and hair disorders, as well as to rejuvenate, even, and smooth the skin.4

Key Constituents

Functional constituents identified in sea buckthorn include alkaloids, carotenoids, flavonoids, lignans, organic acids, phenolic acids, proanthocyanidins, polyunsaturated acids (including omega-3, -6, -7, and -9), steroids, tannins, terpenoids, and volatile oils, as well as nutritional compounds such as minerals, proteins, and vitamins.4,5,11 Sea buckthorn pericarp oil contains copious amounts of saturated palmitic acid (29%-36%) and omega-7 unsaturated palmitoleic acid (36%-48%), which fosters cutaneous and mucosal epithelialization, as well as linoleic (10%-12%) and oleic (4%-6%) acids.12,6 Significant amounts of carotenoids as well as alpha‐linolenic fatty acid (38%), linoleic (36%), oleic (13%), and palmitic (7%) acids are present in sea buckthorn seed oil.6

Polysaccharides

In an expansive review on the pharmacological activities of sea buckthorn polysaccharides, Teng and colleagues reported in April 2024 that 20 diverse polysaccharides have been culled from sea buckthorn and exhibited various healthy activities, including antioxidant, anti-fatigue, anti-inflammatory, anti-obesity, anti-tumor, hepatoprotective, hypoglycemic, and immunoregulation, and regulation of intestinal flora activities.1

Proanthocyanidins and Anti-Aging

In 2023, Liu and colleagues investigated the anti–skin aging impact of sea buckthorn proanthocyanidins in D-galactose-induced aging in mice given the known free radical scavenging activity of these compounds. They found the proanthocyanidins mitigated D-galactose-induced aging and can augment the total antioxidant capacity of the body. Sea buckthorn proanthocyanidins can further attenuate the effects of skin aging by regulating the TGF-beta1/Smads pathway and MMPs/TIMP system, thus amplifying collagen I and tropoelastin content.13

A year earlier, many of the same investigators assessed the possible protective activity of sea buckthorn proanthocyanidins against cutaneous aging engendered by oxidative stress from hydrogen peroxide. The compounds amplified superoxide dismutase and glutathione antioxidant functions. The extracts also fostered collagen I production in aging human skin fibroblasts via the TGF-beta1/Smads pathway and hindered collagen I degradation by regulating the MMPs/TIMPs system, which maintained extracellular matrix integrity. Senescent cell migration was also promoted with 100 mcg/mL of sea buckthorn proanthocyanidins. The researchers concluded that this sets the stage for investigating how sea buckthorn proanthocyanidins can be incorporated in cosmetic formulations.14 In a separate study, Liu and colleagues demonstrated that sea buckthorn proanthocyanidins can attenuate oxidative damage and protect mitochondrial function.9

 

 

Acne and Barrier Functions

The extracts of H rhamnoides and Cassia fistula in a combined formulation were found to be effective in lowering skin sebum content in humans with grade I and grade II acne vulgaris in a 2014 single-blind, randomized, placebo-controlled, split-face study with two groups of 25 patients each (aged 18-37 years).15 Khan and colleagues have also reported that a sea buckthorn oil-in-water emulsion improved barrier function in human skin as tested by a tewameter and corneometer (noninvasive probes) in 13 healthy males with a mean age of 27 ± 4.8 years.16

Anti-Aging, Antioxidant, Antibacterial, Skin-Whitening Activity

Zaman and colleagues reported in 2011 that results from an in vivo study of the effects of a sea buckthorn fruit extract topical cream on stratum corneum water content and transepidermal water loss indicated that the formulation enhanced cell surface integrin expression thus facilitating collagen contraction.17

In 2012, Khan and colleagues reported amelioration in skin elasticity, thus achieving an anti-aging result, from the use of a water-in-oil–based hydroalcoholic cream loaded with fruit extract of H rhamnoides, as measured with a Cutometer.18 The previous year, some of the same researchers reported that the antioxidants and flavonoids found in a topical sea buckthorn formulation could decrease cutaneous melanin and erythema levels.

More recently, Gęgotek and colleagues found that sea buckthorn seed oil prevented redox balance and lipid metabolism disturbances in skin fibroblasts and keratinocytes caused by UVA or UVB. They suggested that such findings point to the potential of this natural agent to confer anti-inflammatory properties and photoprotection to the skin.19

In 2020, Ivanišová and colleagues investigated the antioxidant and antimicrobial activities of H rhamnoides 100% oil, 100% juice, dry berries, and tea (dry berries, leaves, and twigs). They found that all of the studied sea buckthorn products displayed high antioxidant activity (identified through DPPH radical scavenging and molybdenum reducing antioxidant power tests). Sea buckthorn juice contained the highest total content of polyphenols, flavonoids, and carotenoids. All of the tested products also exhibited substantial antibacterial activity against the tested microbes.20

Burns and Wound Healing

In a preclinical study of the effects of sea buckthorn leaf extracts on wound healing in albino rats using an excision-punch wound model in 2005, Gupta and colleagues found that twice daily topical application of the aqueous leaf extract fostered wound healing. This was indicated by higher hydroxyproline and protein levels, a diminished wound area, and lower lipid peroxide levels. The investigators suggested that sea buckthorn may facilitate wound healing at least in part because of elevated antioxidant activity in the granulation tissue.3

A year later, Wang and colleagues reported on observations of using H rhamnoides oil, a traditional Chinese herbal medicine derived from sea buckthorn fruit, as a burn treatment. In the study, 151 burn patients received an H rhamnoides oil dressing (changed every other day until wound healing) that was covered with a disinfecting dressing. The dressing reduced swelling and effusion, and alleviated pain, with patients receiving the sea buckthorn dressing experiencing greater apparent exudation reduction, pain reduction, and more rapid epithelial cell growth and wound healing than controls (treated only with Vaseline gauze). The difference between the two groups was statistically significant.21

 

 

Conclusion

Sea buckthorn has been used for hundreds if not thousands of years in traditional medical applications, including for dermatologic purposes. Emerging data appear to support the use of this dynamic plant for consideration in dermatologic applications. As is often the case, much more work is necessary in the form of randomized controlled trials to determine the effectiveness of sea buckthorn formulations as well as the most appropriate avenues of research or uses for dermatologic application of this traditionally used botanical agent.
