Retinol

As a derivative of vitamin A, retinol is one of the best-known and most effective substances for stimulating skin renewal. Retinol can support collagen synthesis, smooth fine lines, reduce pigmentation disorders, and strengthen skin structure. Retinol also has antioxidant effects and should be gradually introduced in skin treatment, as it can initially cause irritation such as skin redness. Retinol is frequently used in medical cosmetics.
