Nonablative laser and light treatments (other equivalent terms include subsurface resurfacing, photo rejuvenation, and laser toning) have been used for the aesthetic improvement of photoaged skin, acne and scarring. These treatments provide an alternative to traditional full-face laser resurfacing, an ablative modality in which carbon dioxide and/or erbium: YAG lasers are used to remove the entire epidermis and portions of the dermis. It is effective in all skin types.
