Abstract

An increasing number of lasers are in clinical use for treatment of facial rhytides and scars. Each one of these lasers has a significantly different delivery profile while sharing a photothermal mechanism to ablate surface layers of skin. The biological mechanism by which smoother skin results is still under study. Factors in achieving clinical improvement may include tissue ablation, tissue shrinkage, and the inflammatory response produced by the layer of thermally injured dermis which underlies the ablated skin or produced by the need to heal a large raw skin surface. Clinical results suggest that the available lasers all produce some measure of the 'resurfacing effect.' Given the diversity of delivery parameters employed, a comparison of the tissue effects would be useful. We sought to compare the depth of thermal injury and the degree of tissue shrinkage produced by three commonly used resurfacing lasers.
