Medik8 Oxy-R Peptides is a next-generation brightening serum that delivers professional-strength results at home. Featuring a previously unattainable 1% concentration of oxyresveratrol — naturally derived from the mulberry family — this serum targets dark spots, discolouration, and uneven skin tone with clinically proven efficacy.
Unlike conventional brightening products, Oxy-R Peptides uses Medik8’s patented click-activated stabilization system. The formula is suspended in a unique preservation serum and split across two bottles to ensure optimal potency and stability from the very first drop until the last.
Enhanced with a triple-threat peptide complex — including tetrapeptide-30 and acetyl glycyl beta-alanine — this serum not only brightens but also hydrates and smooths, leaving skin visibly more radiant, even, and youthful.

After cleansing in the morning and evening, blend 6 drops of Oxy-R Peptides across the face, neck, and décolletage, avoiding the eye area. Leave to absorb fully before applying your moisturiser.
Important: Oxy-R Peptides is supplied as 2 x 10ml bottles. Each bottle stays potent for 6 weeks after activation. Activate the second bottle only after finishing the first. Store both bottles at room temperature and away from direct sunlight after activation.
Tip: If you are new to Oxy-R Peptides, we recommend a patch test at least 24 hours before first use.
