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 prevent the formation of dark spots to transform the look of dull, uneven skin tones.
Tetrapeptide-30

An illuminating peptide that helps to minimize the formation of visible dark spots.
Acetyl Glycyl Beta-Alanine

Works to support a brighter, more even-looking complexion with less visible dark spots.
Hyaluronic Acid

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

THE SCIENCE BEHIND THE FORMULA

Unmatched in strength and visible results.

DANIEL ISAACS Chief Product Officer

While exceptionally powerful in brightening the look of the skin, oxyresveratrol (Oxy-R) is an incredibly unstable ingredient. This means it can easily lose its power when it comes into contact with light, heat and air. But, with yet another one-of-a-kind stability system, Medik8 has been able to yield the unmatched visible benefits of oxyresveratrol at the previously untapped strength of 1%. Storing 1% Oxy-R within an innovative preservation serum in the bottle's lid to protect its potency, Oxy-R Peptides then uses click-activated packaging technology to ensure the formula remains constantly stable and powerful for maximum visible results.
