While home treatments can be helpful in keeping acne at bay, medical-grade treatments on a regular basis are especially effective. Glycolic acid has been found to be extremely effective in the treatment of acne. Glycolic acid can deeply exfoliate the skin, which allows for the removal of all the dead skin cells and excess sebum. The new skin that is revealed will be smoother, softer, and cleaner. Salicylic acid is often a component of acne treatment because it can inhibit the formation of new acne. Glycolic acid and salicylic acid combine well, so they may be used in a single treatment for people with acne concerns.
