Sea buckthorn is not a subtle ingredient. The oil extracted from its berries is deep orange, intensely scented, and one of the most nutrient-dense plant oils you’ll encounter. It’s been used in traditional medicine across northern Europe and Asia for centuries, and the modern scientific analysis of what’s actually in it explains why that tradition persisted.
In Estonian and Baltic folk medicine, sea buckthorn was known for wound healing and skin nourishment. On Saaremaa island, the plant grows along the coastline, adapted to the specific conditions of the Baltic coast. This is one of those cases where the traditional ingredient and the scientific evidence genuinely reinforce each other.
What makes sea buckthorn exceptional
The composition of sea buckthorn berry oil (particularly the pulp oil from the berries, as distinct from the seed oil) is unusual in several ways. The orange-red colour comes from an extraordinary carotenoid content: sea buckthorn pulp oil contains beta-carotene, alpha-carotene, lycopene, zeaxanthin, and other carotenoids at concentrations significantly higher than almost any other plant oil. Some analyses show carotenoid content of 30,000-100,000 micrograms per 100g, compared to carrot oil at around 8,000-15,000 micrograms per 100g.
These carotenoids function as antioxidants, quenching the free radicals generated by UV exposure and pollution. They also provide precursors to vitamin A, which the body can convert to retinoids for cell renewal and skin repair.
Sea buckthorn is one of the few plant sources of omega-7 fatty acids (palmitoleic acid), which is unusual among plant oils. Omega-7 is a component of human sebum and has been studied for its effects on skin barrier function and wound healing. Some research suggests palmitoleic acid supports tissue regeneration and has anti-inflammatory properties.
The vitamin E content is also notably high, with both tocopherols and tocotrienols present. Vitamin E is a key fat-soluble antioxidant in the skin and contributes to the stability of the oil’s other fragile compounds.
Vitamin C in the berries (not the oil, as vitamin C is water-soluble and doesn’t extract into oil) makes sea buckthorn products based on aqueous extracts, hydrosols, or whole-berry preparations additionally interesting for topical antioxidant applications.
Research on sea buckthorn for skin
Clinical research on sea buckthorn for skin conditions is reasonably good compared to many botanical ingredients. A randomised controlled trial published in the Journal of Nutritional Biochemistry found that sea buckthorn berry oil (taken orally) significantly improved symptoms of atopic dermatitis compared to placebo over a period of four months. The omega-7 content is thought to be particularly relevant for the barrier-supporting effect.
Animal and in vitro studies have shown sea buckthorn accelerates wound healing, reduces UV-induced oxidative damage, and has anti-inflammatory effects. Clinical studies on topical sea buckthorn for wound healing exist from the medical context where the oil has been used in burn care.
For anti-aging, the carotenoid and vitamin E combination provides antioxidant protection against the free radical damage that drives premature skin ageing. The omega-7 content supports barrier function and skin thickness maintenance. These are both relevant and reasonably evidenced mechanisms.
How to use sea buckthorn in skincare
The main practical challenge with sea buckthorn pulp oil is its colour and scent. Pure sea buckthorn pulp oil will give skin an orange tint if used undiluted. This is managed by using it at diluted concentrations (typically 3-10%) in a lighter carrier oil, or by choosing products specifically formulated to balance the intense oil with other ingredients that moderate the colour.
Sea buckthorn seed oil is more neutral in colour (light yellow to pale orange) and milder in scent than the pulp oil, but has a different and less extraordinary composition. The seed oil is rich in omega-3 and omega-6 fatty acids and vitamin E but lacks the exceptional carotenoid content of the pulp oil.
The Superserum SUNDROPS from HOIA is formulated with sea buckthorn among its hero ingredients, balanced with other carefully chosen plant oils to deliver the extraordinary benefits of this Nordic ingredient in a practical, everyday formulation. The deep golden colour is characteristic of authentic sea buckthorn content.
For direct application, a single drop of sea buckthorn pulp oil blended into a facial moisturiser or a lighter carrier oil (such as jojoba or rosehip) provides a meaningful dose of its nutrients without the challenge of full-concentration application. Applied this way in the evening, it supports overnight skin repair and delivers antioxidants without the orange staining that neat application would cause.
Who benefits most from sea buckthorn
Dry and very dry skin types benefit most directly. The combination of omega-7, carotenoids, and vitamin E makes it one of the most nourishing oils available for skin that struggles to maintain its own moisture and lipid barrier.
Mature skin is another primary candidate. The carotenoid-driven antioxidant protection, barrier support, and potential vitamin A precursor activity all address the main concerns of ageing skin without the irritation risk of stronger actives.
Sensitive and reactive skin often responds well to sea buckthorn because of its anti-inflammatory properties and its compatibility with compromised barriers. It’s a nourishing choice for barrier repair situations, though the intense nature of the oil means using diluted preparations is still wise for sensitive skin.
Oily and acne-prone skin should use sea buckthorn more cautiously. The oleic acid content, while not the dominant fatty acid, can contribute to congestion in follicle-prone skin. Seed oil rather than pulp oil is a gentler starting point if you have oily skin and want to experiment with sea buckthorn benefits.
