Key features
Chemical peeling, dermabrasion, and laser ablation are the three main methods of skin resurfacing
Chemical and mechanical resurfacing procedures have a long history of safety and efficacy in ameliorating various skin conditions and improving cutaneous photoaging
Resurfacing procedures represent one part of a comprehensive skin care program that should include photoprotective measures and topical medical and/or cosmeceutical agents
Each resurfacing procedure injures the skin to a specific depth to promote the regrowth of new skin with improved surface characteristics
The degree of clinical improvement, the length of the recovery period, and the risk of complications are all proportionate to the depth of tissue injury chosen and skin type
Selection of suitable patients and proper choice of resurfacing procedure are critical to success
Both dermabrasion and the “TCA CROSS” technique are methods for treating acne scars
Microdermabrasion and microneedling are additional approaches for facial rejuvenation
Prolonged erythema, pigmentary or textural irregularities, infection, delayed healing, and scarring are potential complications of resurfacing
Resurfacing procedures are a rewarding part of dermatologic practice, both for the patient and for the physician
