In dermatology, lasers add another dimension for the treatment of skin diseases. Laser resurfacing can improve cosmetic flaws, such as wrinkles, scars, and sun damage, and is the latest scientific breakthrough in skin rejuvenation. Lasers (short for Light Amplification by Stimulated Emission of Radiation) work by producing an intense beam of light that travels in one direction. This beam can gently ablate skin tissue to improve wrinkles, scars or blemishes. In addition, lasers can also be used to destroy visible blood vessels or to cut skin tissue. Using a laser hand piece, undesired skin cells and wrinkles disappear 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. This procedure also offers increased degree of precision and safety in treating delicate areas.
It is important to understand the limitations of skin resurfacing using lasers. The laser is not a substitute for a facelift, nor can the procedure eliminate excessive skin. However, by tightening loose skin, laser resurfacing can improve certain folds and creases. More importantly, laser resurfacing offers an alternative to traditional resurfacing (dermabrasion) and can also work well in conjunction with other cosmetic skin procedures such as chemical peels.
The final result of laser resurfacing can take up to six months to fully appear. These results are long-lasting, but not permanent. Some people will require re-treatments over the years. Protection from the sun and the institution of a good skin-care regime can help in maintaining a rejuvenated look.
