The A.H.A Peeling Serum with patented natural acids is 1.5 times more effective than salicylic acid and provides a refined skin appearance in just 10 days. The exclusive acid duo of lactic acid and succinic acid helps to reduce skin imperfections, pores, and spots. Glutamic acid regulates sebum production and reduces excess oil. The formulation is enriched with Avène Thermal Water, which soothes, strengthens, and restores balance to the skin. The A.H.A corrective peeling serum has been specifically developed and tested for acne-prone, sensitive skin. It contains only 10 active ingredients, 99% of which are of natural origin.
