Laser resurfacing to improve cosmetic flaws, such as wrinkles, acne scars, and aging and sun-damaged skin, is the latest scientific breakthrough in skin rejuvenation. Using a wand-like laser handpiece, undesired skin cells and wrinkles literally disappear in a puff of mist and are replaced by fresh skin cells. One of the laser's most significant advantages over traditional techniques for skin resurfacing is that treatment is relatively bloodless. The procedure also offers more control in the depth of penetration of the skin's surface, allowing an increased degree of precision and safety in treating delicate areas.
