C-Tetra

Restore radiance and fight visible signs of ageing with C-Tetra. Utilising the antioxidant power of vitamin C and E, the hydrating serums brighten and smooth the complexion, while fighting free radicals to reduce visible signs of ageing.

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 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 12 months after you first opened it.
