Medik8 C-Tetra is a revolutionary ultra-stable vitamin C serum which helps combat sun-induced damage to the skin, trigger collagen synthesis, increase the skins elasticity and density as well as improve the skins texture and brighten the complexion.

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.
C-Tetra has been shown to have up to 4 times the potency L-ascorbic acid and other derivatives such as MAP (magnesium ascorbyl phosphate).
