Medik8 C-Tetra Eye

Harness the anti-ageing and brightening power of our original C-Tetra® facial serum in an ultra-gentle, yet effective treatment designed for the delicate eye area.

It is exceptionally difficult to formulate a vitamin C serum that will retain its power over time.

That's because vitamin C is notoriously unstable, meaning its effectiveness can be compromised when it comes into contact with light, heat or air.

That's why Medik8 have chosen to formulate C-Tetra Eye with an extremely stable form of vitamin C (tetrahexyldecyl ascorbate), so you can be sure that your vitamin C is still as potent and effective 6 months after you first opened it.
