The skin is packed with natural antioxidants that defend it against environmental free radicals. When these environmental free radicals outnumber your antioxidants, they can no longer protect the skin. The free radicals attach to unprotected skin cells, causing irreparable damage, ultimately leading to premature aging. C-Tetra Eye contains tetrahexidecyl 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 crow's 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 skin's defensive lipid barrier with ease, delivering benefits deep within the skin. Vitamin C and vitamin E work synergistically as "network antioxidants," boosting the serum's overall antioxidant effect to keep skin protected throughout the day. How to use After cleansing in the morning, use the spatula applicator to smooth a small amount of C-Tetra Eye onto the under-eye area and brow bone, avoiding the eyelids. Blend gently.
