Laser skin resurfacing uses laser technology to remove or soften wrinkles and scars. The laser is a device that generates an intense beam of focused light, which converts to thermal energy. When applied to skin resurfacing, it provides a controlled shedding of several layers of damaged skin. This exposes a new, fresh layer of skin with a more even color and smoother texture. It also stimulates new cells to grow, thereby tightening the skin and decreasing wrinkling. Laser skin resurfacing can be used on the full face or a specific region of the face such as around the eyes or mouth.
Laser resurfacing is a technique used during laser surgery wherein molecular bonds of a material are dissolved by a laser. It is often used in a medical context, especially in dermatology, for the treatment of acne vulgaris, scars (see acne scar treatment), and spider telangiectasias or "spider veins" - a symptom of ataxia telangiectasia.
