Glycolic acid works at the base of the stratum corneum (the top layers of your skin) and dissolves the ‘glue’ that holds dead skin cells together. This increases cell turnover and the skin becomes smoother more elastic and more even in tone and texture. At the same time Glycolic Acid also stimulates your skin to produce more collagen.
