How does glycolic acid help with oily/acne prone skin?
As dead skin cells build up around hair follicles, they interfere with the natural drainage of oil, causing the hair follicle to clog and fill. The resulting blockage can lead to several problems, including comedones, etc. By loosening the bond holding together the excessive build-up of dead cells, glycolic acid helps remove the blockage and cleanses the pores, allowing the skin to rid itself of these oils naturally.
