What is sea buckthorn and how does it benefit skin?

Immediate Answer: Sea buckthorn (also called sea berry or havtorn in Norwegian) is one of the most nutrient-dense plant-based skincare ingredients available—rich in omega fatty acids (including the rare omega-7), fat-soluble vitamins, and antioxidants. It supports skin renewal, balances hydration, and provides antioxidant protection against environmental damage.

The Science: Sea buckthorn berries contain an unusually complete nutritional profile for a plant ingredient:

• Omega-3, -6, and -9 fatty acids: Structurally identical to fatty acids in skin cell membranes—the skin can directly incorporate these for barrier repair and maintenance
• Omega-7 (palmitoleic acid): Rare in plants; promotes tissue regeneration and is particularly beneficial for mature, dry, or compromised skin
• Vitamin E (tocopherols): Potent antioxidant that neutralises free radicals and protects membrane integrity
• Carotenoids (beta-carotene, lycopene, zeaxanthin): Natural pigments with strong antioxidant and anti-inflammatory properties

Together, these components help the skin repair oxidative damage from UV and pollution, maintain moisture balance, and accelerate the skin's natural renewal cycle.

How sea buckthorn works in Power Glow Serum: In Power Glow Serum, sea buckthorn works synergistically with ferulic acid and vitamin C to create a layered antioxidant defence—each compound neutralises free radicals at different levels of the skin. This combination is particularly effective for sun-damaged and uneven skin because it repairs existing oxidative damage while protecting against future exposure.

Pro Tip: Sea buckthorn's natural orange pigment (from its high carotenoid content) can lightly tint a serum containing it—this is completely normal and is a sign of meaningful ingredient concentration, not an impurity. The tint doesn't transfer visibly to skin at the concentrations used in Power Glow Serum's formula.
