Fractional resurfacing is a new laser treatment modality that creates numerous microscopic thermal injury zones of controlled width, depth, and density that are surrounded by a reservoir of spared epidermal and dermal tissue, allowing for rapid repair of laser-induced thermal injury. This unique modality, if implemented with proper laser-delivery systems, enables high-energy treatments while minimizing risks. In this article, we review the various fractional laser devices, including the new fractional ablative devices, as well as the results of studies on the clinical efficacy of fractional photothermolysis. This technology offers patients significant clinical improvement in photodamage, melasma, and scarring with modest treatment-related downtime and minimal risk of complications.
