Fractional Photothermolysis: A Review and Update

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 laserdelivery
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.
