Medik8: Award-winning Skincare Cosmeceuticals


Medik8 CE-Tetra® is a revolutionary ultra-stable vitamin C serum which helps combat sun-induced damage to the skin, as well as improve the skin’s texture and brighten the complexion. Designed for both men and women in their mid-30s to 50s.

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 CE-Tetra guarantees real vitamin C activity and best of all, unlike L-ascorbic acid (regular vitamin C), CE-Tetra will not exfoliate or irritate skin.

CE-Tetra® contains 7% Tetrahexyldecyl Ascorbate, the most potent and highly stable derivative of vitamin C available. CE-Tetra has been shown to have up to 4 times the potency L-ascorbic acid and other derivatives such as MAP (magnesium ascorbyl phosphate).
