The appearance of hyperpigmentation is improved after just one month*

*Proven via an independent consumer study

Tested over 4 weeks on 50 participants aged 35-70 with hyperpigmentation skin concernsHow It Works
Oxy-R Peptides harnesses the powers of gold-standard brightening agent oxyresveratrol, at a previously untouched concentration of 1%. A gentle yet powerful antioxidant, Oxy-R is used in skincare to target areas of hyperpigmentation, dark spots and post-inflammatory pigmentation. Found to be 33x times more effective than kojic acid[1].

While exceptionally powerful, Oxy-R is an incredibly unstable ingredient. With yet another one-of-a-kind stability innovation, Medik8 have carefully curated a patented system to yield the unique benefits of ultra-high strength stabilised oxyresveratrol. Keeping the 1% Oxy-R stored in a preservation serum in the lid to protect its potency, Oxy-R Peptides uses Click-Activated packaging technology to ensure the formula remains stable from activation to final drop.

Oxy-R Peptides offers a triple-threat to hyperpigmentation, with twin brightening peptides working alongside Oxy-R to improve the visible tone of the skin. Tetrapeptide-30 works to help reduce visible discolourations and uneven skin tone, while acetyl glycyl beta-alanine works to help reduce localised areas of pigment from appearing on the skin.
