Medik8 C-Tetra

Medik8 C-Tetra is a lightweight, fast-absorbing antioxidant serum designed to defend the skin against daily environmental stressors while brightening and revitalising the complexion. Powered by Tetrahexyldecyl Ascorbate, a gentle yet highly effective lipid-soluble form of vitamin C, it penetrates deeply to help stimulate collagen, even skin tone and restore luminosity.

The dry-touch oil texture melts effortlessly into the skin without heaviness or residue, making it perfect for first-time vitamin C users, sensitive skin types or those wanting a simple, effective morning serum.
