Designed for both men and women in their mid-20s to 40s.Medik8 C-Tetra is a revolutionary ultra-stable vitamin C skincare 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. 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. 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).

Review: The best skin product ever - I was told about this product by a beautician and it's been a revelation. My skin is much softer and I need hardly any moisturiser after 4 months of use. I've recommended it to my sister and son, who both suffer from very dry skin on their face and they saw an immediate improvement. I use 4 drops every morning and use Medik8 Retinol 3TR every other evening. I love it!
Review: Healthy skin - This was recommended to me by my beautician. I tried it after using the much hyped (an expensive!) Clarins Super Serum. I have found that this serum has given my skin a healthier glow, does not leave it greasy and has cleared up my combination patches. I use it twice a day before day and night creams. Definitely worth the price and competes with the other big players on the market.
