Sea Buckthorn for Skin
Hippophae rhamnoides
A thorny mountain shrub carrying a fatty acid almost no other plant provides — and the only ingredient in this library that will stain your pillowcase.
At a glance
Two oils, one plant
Sea buckthorn is a hardy, thorny shrub growing at altitude across Europe and Asia, including the Himalayan region. Its berries are a startling orange, and it has been used in Asian traditional medicine for over a thousand years.
Here is the part almost no label explains: sea buckthorn yields two different oils, and they are not interchangeable.
- Seed oil — roughly 33–36% linoleic acid and 30–36% alpha-linolenic acid. An omega-6 and omega-3 oil, closer in character to rosehip.
- Pulp or berry oil — 32–42% palmitoleic acid. This is the omega-7 oil, and it is what makes sea buckthorn unusual.
Composition also shifts with growing conditions, cultivar, extraction and processing. If a product does not say which oil it uses, you cannot know what you are buying.
Why omega-7 is interesting
Palmitoleic acid is rare in the plant kingdom and present in human sebum. That is an unusual combination — most plant oils give you fatty acids your skin uses as raw material, but few give you one your skin already makes.
Researchers have looked at it for barrier support and epithelial repair on that basis. One paper puts omega-7 at around 48% of sea buckthorn oil overall.
It sits alongside sunflower's linoleic acid and jojoba's wax esters as the third distinct way a plant lipid can resemble your own.
What the cell studies show
Human keratinocytes and fibroblasts exposed to UVA and UVB and treated with sea buckthorn seed oil showed partial prevention of UV-induced reactive oxygen species, higher levels of glutathione, thioredoxin and vitamins E and A, and activation of Nrf2 — the master switch for the cell's own antioxidant enzymes.
The result was measurably less lipid peroxidation. That matters because peroxidised lipids are damaged barrier lipids, and a damaged barrier is what makes skin look dull and feel tight.
The deep orange colour comes from carotenoids, which contribute antioxidant capacity of their own — the same family discussed on the carotenoid supplement entry.
How strong is the evidence?
Weaker than the marketing suggests. The mechanistic work is genuinely good, but it is cell culture. The wound-healing studies most often cited were conducted in sheep burn models, not humans.
There is dietary work showing supplementation with seed and pulp oils changed the fatty acid composition of skin phospholipids in people with atopic dermatitis — interesting, and a medical population rather than a cosmetic one.
A recent review put it plainly: sea buckthorn oil should not be presented as a treatment for eczema, psoriasis, acne, wounds or any diagnosed skin condition. We agree, and we would add that a great deal of what is claimed for it online goes far past what has been shown.
Our position: a rich, genuinely nourishing oil with an unusual fatty acid profile and real antioxidant content. Excellent for skin that feels depleted. Not a treatment for anything.
The practical warning nobody gives you
Those carotenoids are pigments, and they behave like pigments. Undiluted sea buckthorn oil is deep orange and it stains — pillowcases, towels, pale clothing, and temporarily the skin itself if you use too much.
Use a few drops, blend it with another oil or a cream, apply at night, and use an old pillowcase until you know how your skin takes it. Most well-formulated products dilute it enough that this is not an issue, but a neat oil absolutely will.
