Oxy-R Peptides | 2x10mlOxy 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 block the overproduction of pigment that can lead to visible discolourations and uneven skin tone, while acetyl glycyl beta alanine works to help stop localised areas of pigment from appearing on the skin.
