Rosehip seed oil is the only vegetable oil to contain retinol (vitamin A). It is also high in the essential fatty acids, linoleic acid (omega-6) and linolenic acid (omega-3), as well as the antioxidant lycopene and beta-carotene. It is often used in skincare products. Apply undiluted rosehip seed oil twice daily to the face and body to treat wrinkles, scars, sun damage, dermatitis, stretch marks and discoloration. Use rosehip seed oil as a daily moisturizer for very dry skin.
