AHAs may also reduce the size of enlarged pores, which are commonly seen in acne-prone skin. Skin cell turnover from exfoliating glycolic and lactic acids can even reduce acne scars. Some acne products also contain other AHAs, such as citric and malic acids, to help soothe inflamed skin.

Is AHA or BHA better for acne scars?

AHA is best for dry skin and surface-level skin concerns like acne scars. BHAs are best for oily and acne-prone skin types.

Can AHA reduce acne scars?

Alpha hydroxy acids (AHAs) are often found in products made to treat acne since they help to remove dead skin and prevent clogged pores. Even better, AHAs can also help make acne scars appear less noticeable. The mild acid exfoliates the outer layer of the skin to help remove discoloration and rough skin.
