Medik8 C-Tetra is a lightweight, uplifting formula that stimulates the production of collagen and elastin to help reduce fine lines and wrinkles, as well as visibly brightening the complexion and balancing 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 crafted in a water-free formula to be 100% stable, which means that the vitamin C does not degrade over time. This ensures that your formula remains highly potent from the very first use to the final drop.

How to use Medik8 C-Tetra
