Science
Mechanism of Action
The comprehensive antioxidant activity of Hippophae Rhamnoides Fruit Oil is attributed to its high concentration of vitamins A, C, E, carotenoids, flavonoids, and polyphenols, which collectively safeguard the skin from oxidative stress and environmental damage. It exerts anti-inflammatory effects, effectively calming and soothing irritated skin. A key component, omega-7 fatty acids (palmitoleic acid), mimics the skin's natural lipids, thereby reinforcing the skin barrier, reducing transepidermal water loss (TEWL), and significantly improving skin hydration. Its rich fatty acid composition further contributes to moisturizing capabilities, supports wound healing, and stimulates collagen production.

Key findings
- 01 An oil-in-water emulsion containing 5% *Hippophae rhamnoides* extract demonstrated significant improvements in skin hydration and a reduction in transepidermal water loss over an 84-day period in healthy human subjects, when compared to a placebo.
- 02 In *in vitro* studies, sea buckthorn seed oil at a concentration of 500 ng/mL, applied to human keratinocytes and fibroblasts, was effective in preventing UV-induced disturbances in redox balance and lipid metabolism, suggesting potential photoprotective benefits.

Stability
The naturally occurring vitamin C within Hippophae Rhamnoides Fruit Oil exhibits superior stability in topical formulations compared to synthetic L-ascorbic acid, which is prone to rapid degradation upon exposure to light and air.
Safety
Safety Profile
Hippophae Rhamnoides Oil is generally well-tolerated by most skin types, including sensitive skin, with a low risk of allergies. However, its characteristic red-orange pigment may temporarily stain the skin. While considered safe 'as used' by the CIR, some sources note a lack of high-quality evidence for specific clinical uses, and in high concentrations, it carries a medium comedogenicity risk, often prompting recommendations for dilution with a carrier oil for facial application.
