Laser resurfacing is a cosmetic procedure commonly used to treat fine lines, wrinkles and other signs of aging. The technique can help reduce the appearance of light to moderate wrinkling around the eyes, cheeks and mouth, according to the Mayo Clinic. Laser resurfacing also smooths uneven complexions and fades age spots and scarring.
Function
Laser resurfacing is a type of ablative--or wounding--procedure. It uses a beam of light energy to destroy target areas on the outer layer of skin. The laser also heats up the underlying tissue, stimulating the production of collagen. As the damaged area heals, it is replaced by tighter, more evenly textured skin, says the Mayo Clinic.
Benefits
As explained by Dr. Jean Loftus, author of "The Smart Woman's Guide to Plastic Surgery," wrinkles are noticeable because they are depressed and create shadows. The purpose of any wrinkle treatment is to level the skin's surface. Ablative resurfacing does this by triggering collagen production to fill in wrinkles while also removing the built-up skin around them.
Procedure
Ablative resurfacing treatments are sometimes preceded by a six-week course of tretinoin, a prescription cream designed to treat fine wrinkling, roughness and pigment changes, according to the Mayo Clinic. A few days before the procedure, doctors may recommend the use of antibiotics to prevent cold sores and skin-bleaching creams to prevent hyperpigmentation. The procedure typically takes less than two hours and is done on an outpatient basis. But factors including the size of the treatment area can affect procedure time and determine whether an overnight stay is required.
Side Effects and Considerations
Resurfacing treatments are painful and require the use of a local or general anesthetic. The procedure also entails a lengthy recovery time. Immediately after treatment, skin will be painful, raw and blistered. The treated area will also be swollen and weepy for about two weeks. Furthermore, the strongest laser techniques can cause redness that lasts for up to four months, according to the website Info Plastic Surgery.
Effectiveness
Ablative resurfacing helps reduce the appearance of wrinkles. But it will not make them disappear, nor is it a permanent solution, warns Info Plastic Surgery. Some people require several treatments before achieving the desired results. Once these results are achieved, they typically last five to seven years.
