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).

    The best Vitamin C serum I have ever tried. So good, I wouldn’t dream of being without it now.

  2. Rated 5 out of 5


    Smells beautiful and makes my skin look fabulous instantly. I would dream of being without it. I started on the weaker version (C-Tetra), and then upgraded to this one. I am so glad I did. I’m 53, and so needed the extra boost :-)

  3. Rated 5 out of 5


    Great Vitamin C serum! I am loving Medik 8 products! My acne-prone, combination skin looks super radiant and clean. I have not had any breakouts. I highly recommend trying this Vitamin C serum. It is definitely part of my beauty regimen.
