Glycolic acid can penetrate deep into the sebaceous glands, inhibit their excessive oil secretion, and reduce the greasy skin feeling from the root. With long-term use, skin oil secretion can be maintained at an appropriate level, no longer shiny.

Glycolic acid can inhibit the growth and reproduction of such bacteria, reduce the chance of acne, and keep the skin healthy.
