Probably no advance in medicine has had more of an impact than the development of laser surgery. Lasers work by emitting a powerful beam of light, removing the uppermost layer of the skin. As the new living cells heal the area, the skin tightens, fine lines are removed, and deeper lines are softened.
Lasers can be used to treat sun-damaged skin, mild acne scarring, age spots and skin discolorations, facial scars, and wrinkles. Other types of lasers are used to treat spider and/or leg veins, remove unwanted hair, and remove tattoos.
The advantages of laser surgery include the lack of need for general anesthesia or hospitalization. In fact, some laser procedures may be done in the office.
