CO₂ laser resurfacing is performed to selectively vaporize the top layer of the skin, permitting the healthier underlying skin to regenerate new collagen and epidermal cells.

Using the CO₂ laser, the physician precisely controls the beam of light, which minimizes a patient’s risk of scarring and other complications. Discomfort is usually minor both during and after the procedures.

Initially there may be prominent swelling and crusting. These resolve over the first week. The new skin is quite pink and patients will typically elect to use makeup to conceal the color. Complete healing occurs over 30 to 90 days and results in smoother, tighter skin.
