Key Ingredients
3% Stabilised Vitamin C (tetrahexyldecyl ascorbate)

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

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.

Hyaluronic Acid

With a unique ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture from the lower layers of the skin into the upper layers. This leaves the complexion visibly nourished and supple.
