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.
