Glycolic acid is a natural acid found in sugar cane, according to the Mayo Clinic. When applied to your skin, its exfoliating effects remove dead skin cells and unclog pores.The University of Maryland Medical Center (UMMC) says glycolic acid peels are among the mildest of the peel formulas and can help treat a number of skin conditions. Glycolic acid may effectively even out pigmentation, control acne, diminish fine lines and result in smoother and fresher appearing skin. The American Society of Plastic Surgeons (ASPS) says chemical peels are not without uncertainty and risk.
Changes in Skin Tone
There is a risk of skin tone changes when undergoing a glycolic acid peel. According to Dermalase.net, this alteration in color can be temporary or permanent. Women who are pregnant or taking birth control bills and people with a family history of brownish facial discoloration may be at greater risk of pigmentation problems following a glycolic peel.
Irritation
The UMMC says glycolic and other alphahydroxy acids (lactic, fruit acid) may cause a stinging of the skin. Some people will experience redness, irritation and excessive dryness that may include flaking, crusting or scaling. The ASPS says once your skin adjusts to glycolic acid, these reactions will most likely diminish.
Scarring
Scarring is another potential complication of glycolic and other chemical peels. According to Dermalase.net, if scarring occurs from a peel, most cases can be successfully treated.
Cold Sores
People who are prone to cold sores or Herpes simplex infections may find that a glycolic chemical peel prompts a recurrence of fever blisters or cold sores. Dermalase.com says people who are worried about a cold sore flare-up due to a glycolic acid treatment can have a small area of skin tested before proceeding with the peel.
