Glycolic acid is one of the most commonly used forms of hydroxy acid. It helps to peel away dead skin cells, with the American Academy of Dermatology reporting that it can leave your skin feeling softer and appearing much smoother. The acid can be found in a wide range of skincare products, including skin creams and cleansers.
