Indications

Medium-depth chemical peels are best suited for the treatment of superficial epidermal lesions, lentigines, actinic keratosis, pigmentary dyschromias, textural irregularities due to acne scarring, and mild to moderate rhytids associated with photoaging [49]. This level chemical peel is also used as an adjunct to laser resurfacing or deep chemical peels, to blend the lines of demarcation between treated and untreated skin. In patients with more significant periorbital and perioral rhytids, the deeper penetration of laser may be indicated for improvement, but medium-depth peels may be sufficient for the intervening areas of facial skin [53, 54, 55].Moderate inflammatory acne, acne scarring, AK, warts, and facial skin aging are among the conditions treated successfully by the pyruvic acid peel [48]. Chun et al. utilized the focal application of TCA at concentrations of 10–65% to safely remove or improve benign pigmented lesions, including seborrheic keratoses, lentigines, freckles, and melasma in dark-skinned patients [56]. By combining these therapeutic options, the patient’s healing time and risk of posttreatment morbidity are both reduced [49].
