The skin is full of natural antioxidants that defend it against environmental free radicals. When these environmental free radicals overwhelm the skins antioxidants, they can no longer protect it. The free radicals attach themselves to unprotected skin cells, causing irreparable damage, which ultimately leads to premature aging. C-Tetra Eye contains tetrahexyl ascorbate, a super-stable form of vitamin C that boosts antioxidant defense levels around the delicate eye area. It also stimulates collagen production to reduce the appearance of fine lines, wrinkles, and crows feet, leaving the eye area looking more youthful and awake. As a fat-soluble form of vitamin C, tetrahexyl ascorbate is able to penetrate the skins defensive lipid barrier with ease, providing benefits deep within the skin. Vitamin C and vitamin E act synergistically as network antioxidants, enhancing the serums overall antioxidant effect to keep skin protected all day long. How to use After cleansing in the morning, use the spatula applicator to spread a small amount of C-Tetra Eye over the under-eye area and brow bone, avoiding the eyelids. Blend gently.
