When used at 40 percent strength, glycolic peels improve the appearance of fine lines, wrinkles, acne, sun damage and age spots. Considered a superficial peel, 40 percent glycolic peels treat the outer layer of skin, and the results last for up to one month, notes Mayo Clinic.

Glycolic acid is a water-soluble alphahydroxy acid of small molecular weight that rapidly penetrates into the skin.
