Medik8 C-Tetra is an anti-ageing Vitamin C serum, in an ultra-stable form, which helps to alleviate extrinsic photodamage, stimulate collagen production, and increase skin's elasticity alongside improving the skins texture and improving clarity and complexion. Optimal anti-ageing serum for young adults aged 20-40 years. Vitamin C is typically an unstable molecule, and most Vitamin C's are unstable and inactive by the time they are applied to the skin. However, C-Tetra will not exfoliate or irritate skin unlike L-ascorbic acid, as it contains 3% Tetrahexyldecyl Ascorbate, the most potent and highly stable derivative of Vitamin C available.
