In laser resurfacing, sometimes called "laser peel," a carbon dioxide (CO2) laser is used to remove areas of damaged or wrinkled skin, layer by layer. The procedure is most commonly used to minimize the appearance of fine lines, especially around the mouth and the eyes. However, it is also effective in treating facial scars or areas of uneven pigmentation. Laser resurfacing may be performed on the whole face or in specific regions. Often, the procedure is done in conjunction with another cosmetic operation, such as a facelift or eyelid surgery.
