Medik8 Advanced Day Ultimate Protect SPF 50+ contains a combination of premium, modern chemical sunscreens, carefully selected for their high performance, photostability and skin compatibility. Encapsulated photolyases, derived from plankton extract, are light-activated DNA repair enzymes that support the skin’s natural defences against UV-induced DNA damage. Photolyases help prevent fine lines, wrinkles and UV-induced hyperpigmentation. Bilberry seed oil is rich in beta-carotene and acts as a natural shield against blue light. Blue light can cause free radical damage and lead to hyperpigmentation. Horehound extract is a powerful antioxidant that provides essential protection against pollution-induced damage. It helps to strengthen the skin barrier. The protective peptide carnosine, which is naturally produced by the body, counteracts glycation. Glycation involves the binding of skin-damaging sugars to the collagen in the skin. Carnosine helps prevent the formation of wrinkles and offers protection against infrared. Infrared plays a role in the breakdown of collagen, among other things. Nourishing squalane and hydrating hyaluronic acid provide the skin with long-lasting hydration and they smooth lines and wrinkles.
