The Guanjing Peeling Foot Mask (40g) is an intensive, at-home exfoliating treatment designed to remove dead skin, calluses, and rough patches from the feet. Formulated with Alpha Hydroxy Acids (AHAs) like Glycolic and Lactic Acid, it chemically dissolves the bonds holding dead skin cells together, causing them to shed over a period of 1 to 2 weeks.
