The evidence in words
What it is
Sea buckthorn berries and seeds yield an oil rich in omega-7 (palmitoleic acid), carotenoids and vitamin E, used for skin and mucous-membrane health.
How it works
Its omega-7 and antioxidants support mucous-membrane and skin-barrier integrity and tear-film quality.
What the evidence shows
Trials show oral sea buckthorn oil improves dry-eye symptoms and tear osmolarity, and supports skin hydration/barrier and vaginal mucosal health in menopause. Broader cardiometabolic claims are weaker. A legitimately useful mucous-membrane oil.
Safety & interactions
Very safe; mild GI effects; mild antiplatelet potential at high doses.
Bottom line
A well-tolerated omega-7 oil with real dry-eye and skin/mucosal-barrier benefits — a reasonable, gentle option for those issues.
