- The most common side effects were stinging, burning, and irritation
Hyperpigmentation
Some evidence
Glycolic Acid: 16 studies tested it on its own. See all 25 studies
What the studies found
- Most studies found glycolic acid helped fade dark spots or patches
- It often worked better when used with other treatments than those treatments alone
- Some studies found it improved melasma and post-acne dark marks while also improving skin texture
- The most common side effects were irritation, discomfort, and short-lived skin reactions, with rare lasting light spots
Acne
Some evidence
Glycolic Acid: 13 studies tested it on its own. See all 22 studies
What the studies found
- Most of these studies found it helped clear acne
- It often reduced blackheads and whiteheads, and some studies also found fewer red, sore spots
- It cleared acne more than a placebo in some studies
- It worked about as well as some other acne peels and creams in several studies
- The most common side effects were peeling and other early skin irritation
Texture/Pores
Not proven yet
Few or mixed studies. This claim isn't established.
Glycolic Acid: 4 studies tested it on its own. See all 5 studies
What the studies found
- The results were split, so there is no clear answer yet on texture and pores
- Some studies found glycolic acid improved skin texture, roughness, and skin clarity
- Some studies found it softened fine lines, but one found wrinkle changes were not clearly different
- The most common side effects were stinging and burning, and some studies found more side effects than comparison treatments
