THE SCIENCE BEHIND THE FORMULA
Circular Chevron Icon

Leaves the eye area visibly youthful and awakened.

DANIEL ISAACS Chief Product Officer

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 we 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.
