Glycolic acid is one of the alpha-hydroxy acids or AHAs. The alpha-hydroxy acids also include citric, lactic and tartaric acid. All of these acids remove dead and damaged cells. In fact, this is one reason why many natural or home made masks that are designed to remove dead cells contain the pulp or juice of some fruit that is rich in citric acid. This is also the reason why milk which is a few hours old, which is rich in lactic acid, has been used for generations in facial washes and cleansers to produce younger looking skin.
When dead and damaged cells are removed by alpha-hydroxy acids such as glycolic acid, the skin looks younger and has a more even tone. People with age spots and discoloration can also use glycolic acid to treat these conditions. Products that contain glycolic acid are effective at removing acne scars as well.
