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, which causes a superficial burn of the skin. As new living cells replace layers of dead skin cells, the skin tightens and grows back smoother and wrinkle-free.
Among the advantages of laser surgery is that there is usually no need for general anesthesia or hospitalization and there is no cutting or blood involved.
Lasers are effective for treating sun-damaged skin, mild acne scarring, age spots and skin discolorations, and many facial scars and wrinkles. Other conditions that respond well to laser surgery include spider and/or varicose veins, and the treatment is also effective for hair removal, and tattoo removal.
