Medik8 C-Tetra is a super-light daily vitamin C serum that restores radiance and fights visible signs of ageing. Antioxidants vitamin C and E help combat sun and pollution-induced damage. This uplifting formula stimulates the production of collagen and elastin to help reduce fine lines and wrinkles, as well as visibly brighten the complexion and balance skin tone.

Using a lipid-soluble form of vitamin C called tetrahexyldecyl ascorbate, the formula penetrates deep into skin to provide powerful antioxidant protection with minimal irritation. C-Tetra has been carefully created in a water-free formula, which means that the vitamin C does not degrade over time and remains highly potent to the last drop.

This fast-absorbing vitamin C serum is ideal for those looking for skin rejuvenation, especially those who are new to vitamin C.
