It belongs to the family of bionic acids, substances that represent the evolution of alphahydroxy acids. It promotes a slower exfoliation integrated with an interesting antioxidant and moisturizing action, leaving the skin immediately softer and smoother. It also binds heavy metals, in particular iron, counteracting the formation of free radicals and is therefore ideal for renewing skins stressed by pollution and city life. It works in synergy with glycolic acid improving the appearance of the skin texture.
