Key Ingredients
1% Oxyresveratrol (Oxy-R)

Naturally derived from the mulberry family, oxyresveratrol (pronounced 'ox-ee-ress-vera-trol') is one of the most powerful skin-brightening agents available in skincare. It helps to block the action of tyrosinase (the key enzyme responsible for forming pigment in the skin) to transform the look of dull, uneven skin tones.

Tetrapeptide-30

An illuminating peptide that helps to minimise the production of tyrosinase, to block the overproduction of melanin that leads to visible dark spots.

Acetyl Glycyl Beta-Alanine

A brightening peptide solution that works to help block the transport of melanin to the skin cell, where the overproduction of pigment becomes visible on the skin.

Multi-Weight Hyaluronic Acid

With the ability to attract and retain more than 1,000 times its own weight in water, multi-weight hyaluronic acid draws moisture into multiple layers of the skin; leaving the complexion deeply hydrated and visibly supple.
