    A low-irritation form of vitamin C that delivers exceptional antioxidant protection against harmful free radical damage while supporting collagen production for a visibly even, more youthful-looking complexion.

    An almost skin-identical lipid which helps to support the natural skin barrier by nourishing the complexion.

    Naturally rich in nutrients and fatty acids, maracuja oil deeply nourishes your skin while providing additional antioxidant protection against free radical damage.



  • Optimised Red Ginseng

    Boosts the serum’s brightening powers while stimulating collagen production for more youthful-looking skin.



  • Vitamin E

    A powerful antioxidant that provides additional antioxidant protection against the ageing effects of free radicals. It also helps to boost the power of vitamin C for optimum visible results.

THE SCIENCE BEHIND THE FORMULA

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.
