This method has been used for years to treat different skin issues, including wrinkles, scars, warts, enlarged oil glands on the nose, and other conditions.

The newest version of CO2 laser resurfacing (fractionated CO2) uses very short pulsed light energy (known as ultrapulse) or continuous light beams that are delivered in a scanning pattern to remove thin layers of skin with minimal heat damage. Recovery takes up to two weeks.
