AHA Renewal Serum is a clarifying formula with an alpha hydroxy acid that gently but thoroughly exfoliates, and hydration to reduce the visible signs of aging and promote brighter, firmer, and more radiant skin. Lactic acid (8%) removes dead skin layers, speeds up cell turnover, reduces the appearance of discoloration, and smooths the appearance of fine lines and wrinkles. Allantoin, sodium hyaluronate, and vitamin B5 hydrate, while green tea and arnica soothe the skin.
