'Nonablative laser resurfacing' is a new treatment for photoaged skin, the aim of which is to wound the upper dermis in order to induce dermal fibrosis and improve the clinical appearance. Unlike conventional laser resurfacing or dermabrasion, the epidermis is protected and retained to avoid the problems associated with open wounds and reepithelialization. A number of lasers and light sources have been developed or adapted for this purpose.
