Sea Buckthorn for Skin
In brief
What it is: A hardy, thorny mountain shrub (Hippophae rhamnoides) whose bright orange berries yield two distinct fatty-acid oils.
Key benefits: Rare omega-7 (palmitoleic acid) also found in human sebum; antioxidant carotenoids and tocopherols; barrier support; less lipid peroxidation.
Best for: Very dry, mature or weathered skin.
How we use it: Used in our Anti-Aging Firming Facial, Lift & Sculpt Manual Facial and Silk & Glow Body Polish.
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.

How to use sea buckthorn oil
Choose the right oil first
Because the two oils are so different, start by deciding which one you actually want.
- Pulp / berry oil (omega-7) — deep orange, rich and nourishing; best for very dry, mature or weathered skin. This is the one that stains.
- Seed oil (omega-3 and omega-6) — lighter, higher in linoleic acid, and a better match for combination or breakout-prone skin.
How to apply it
A little goes a long way. Use two to four drops at night as the last step in your routine, ideally over a humectant such as hyaluronic acid or glycerin so the oil seals in the water underneath. Blending it with a plainer oil like sunflower or jojoba, or with your night cream, both dilutes the colour and stretches the bottle.
Oral versus topical
Sea buckthorn is also sold as an oral supplement. Dietary studies have shown it can shift the fatty-acid make-up of skin, but that work was done in people with a diagnosed skin condition, and eating an oil is a different tool from applying one. As always, food first, and check with your doctor before starting any supplement.
Who it suits
Sea buckthorn is at its best on skin that feels genuinely depleted — dry, tight, or worn by years of Florida sun and salt water. Very oily or acne-prone skin may prefer the lighter seed oil, or may skip it. Patch-test first, never use it neat if you are prone to reactions, and remember it nourishes skin but does not replace sunscreen.
Sea buckthorn for skin: frequently asked questions
Seed oil or pulp oil — which should I choose?
It depends on your skin. Pulp or berry oil is the omega-7 oil: deep orange, rich, and best for very dry, mature or weathered skin. Seed oil is lighter and higher in linoleic acid, which suits combination or breakout-prone skin better. If a product does not say which oil it uses, you cannot really know what you are buying.
Does sea buckthorn oil stain skin and fabric?
Yes. The carotenoids that make the berries orange behave like pigments, so undiluted oil can stain pillowcases, towels and pale clothing, and temporarily tint the skin if you use too much. Use just a few drops, blend it into a cream or another oil, apply at night, and use an old pillowcase until you know how your skin takes it.
Can I use sea buckthorn oil on my face every day?
For dry or mature skin, a few diluted drops at night can be used daily. Oily or acne-prone skin may do better with the lighter seed oil or with less frequent use. Patch-test any new oil first and build up slowly.
Is oral sea buckthorn better than topical?
They are different tools rather than better or worse. A topical oil delivers fatty acids and antioxidants to the skin's surface, while an oral supplement can gradually change the fatty acids in your skin from the inside. Neither is a treatment for a skin condition, and a food-first approach is the sensible starting point.
Is sea buckthorn oil safe for sensitive skin?
It is generally well tolerated, but as with any oil you should patch-test it first and avoid applying it neat and undiluted. It is a nourishing cosmetic oil, not a treatment for eczema, psoriasis or any diagnosed condition — those should be assessed by a doctor.
