THE SCIENCE BEHIND THE FORMULA
Circular Chevron Icon
science behind Zoom In Icon

C-Tetra Luxe is the pinnacle of our C-Tetra range, containing 14% tetrahexyldecyl ascorbate; double that of our original C-Tetra serum.

It also boasts an infusion of radiance-boosting antioxidants delivered in a nourishing squalane base, making it the perfect all-rounder within our vitamin C range.

We recommend this for the majority of skin types including those looking for supercharged age-defying results, as well as drier and dehydrated skin types.

C-Tetra Luxe is unique as it remains gentle on the skin despite its high concentration of vitamin C.
