C-Tetra Cream includes tetrahexyldecyl ascorbate, a highly stable form of vitamin C that amplifies the skins antioxidant defense levels. More than just a product, this cream has multiple functions, also stimulating collagen production to diminish the appearance of fine lines and wrinkles. The result is revitalized, radiant, and rejuvenated skin. Because it is fat-soluble vitamin C, it can easily penetrate the skins protective lipid barrier, delivering benefits to the deeper layers. The combination of vitamin C and vitamin E works synergistically as a kind of antioxidant network, thus maximizing the creams overall antioxidant effect.
