Complications of medium depth and deep chemical peels.

Superficial and medium depth peels are dynamic tools when used as part of office procedures for treatment of acne, pigmentation disorders, and photo-aging. Results and complications are generally related to the depth of wounding, with deeper peels providing more marked results and higher incidence of complications. Complications are also more likely with darker skin types, certain peeling agents, and sun exposure. They can range from minor irritations, uneven pigmentation to permanent scarring. In very rare cases, complications can be life-threatening.
