Rosehip seed oil is one of the richest plant sources of Vitamin C and A. Vitamin C has been proven to effectively stimulate collagen production, penetrate deeply to reduce redness, while Vitamin A, or retinol, encourages cell turnover boosting overall radiance. The essential fatty acids within rosehip seed oil penetrate deeply into the skin where they work to neutralize free radicals, reduce fine lines and wrinkles, and increase the skin’s permeability. The unique combination of fatty acids and vitamins make rosehip seed oil a surprisingly great natural remedy for hyperpigmentation and sun-damaged skin.
