Laser resurfacing is a very controlled burning procedure during which a laser vaporizes superficial layers of facial skin, removing not only wrinkles and lines caused by sun damage and facial expressions, but also acne scars, some folds and creases around the nose and mouth, and even precancerous and benign superficial growths. In a sense, the laser procedure creates a fresh surface over which new skin can grow.

Collagen is a key fibrous protein in the skin's connective tissue, and it helps give the skin its texture. Natural aging and such factors as sun damage and smoking help break down the collagen layer so that the skin's once smooth surface develops wrinkles. New, more youthful collagen actually forms after laser treatment.

Laser resurfacing can often make patients look 10 to 20 years younger, and the results can last for eight to 10 years.

Selecting a laser surgeon is just like picking a qualified doctor for any medical treatment. The Internet is a good place to start the search. Consumers can find thousands of Websites, including those for specialists, laser and plastic surgery societies, and information pages.
