AHA stands for Alpha Hydroxy Acid. 

AHAs, natural extracts of fruit acids, are known as the leading active ingredients for renovating the skin and giving a glow to the complexion. They accelerate cell renewal by weakening the cohesion of the lower cells of the epidermis (desquamation phenomenon). They promote hydration and act on the elasticity of the skin thanks to their capacity to absorb water. They stimulate intercellular communication and collagen production.

 They smooth the skin by ridding it of its dead cells, bringing an immediate healthy glow.
