What is glycolic acid?
Glycolic acid is the smallest alpha hydroxy acid — naturally derived from sugar cane. Its low molecular weight allows fast penetration of the stratum corneum and rapid dissolution of the bonds holding dead skin cells together, driving renewal, brightening, and texture improvement.
