Non-ablative and ablative devices are the most commonly used minimally-invasive treatments for skin rejuvenation. Current devices on the market for rejuvenation include the lasers such as the Fraxel Restore, the Halo, the Helios III, the Pico, the ThermiVa and the DiVa which have all been shown to have efficacy for the rejuvenation of the face, décolletage, hands and vagina. In this study we propose to compare the efficacy and side effect profile of these devices for skin rejuvenation of various areas of the body including the face, décolletage, hands, trunk, upper and lower extremities, and vagina.
