Antioxidants are vital to maintaining optimal skin health just as they are to the rest of the body. They help to counteract the damaging effects of free radicals, while also providing powerful age-defying properties. Antioxidant formulas assist in calming visual redness while providing visible brightening effects. A full range of potent antioxidant formulas are available from iS CLINICAL, including the ADVANCE+ line which incorporates a scientifically-advanced, stabilised form of L-ascorbic acid (vitamin C).
