Designed for both men and women in their mid-20s to 40s. Regular vitamin C is very unstable and many typical vitamin C products are inactive by the time they are used on the skin, in some cases, they have become pro-oxidant and actually generate free radicals! Ground-breaking stability data on C-Tetra guarantees real vitamin C activity and best of all, unlike L-ascorbic acid (regular vitamin C), C-Tetra will not exfoliate or irritate skin. C-Tetra® contains 3% Tetrahexyldecyl Ascorbate, the most potent and highly stable derivative of vitamin C available.
