There are two types of lasers that are most commonly used for resurfacing which are carbon dioxide (CO2) lasers and erbium lasers. Each laser treats the skin cells at a surface level, which means this isn’t a deep treatment. CO2 laser resurfacing emits short-pulsed light energy or continuous light beam to create micro-damage sites. This minimal heat damage stimulates collagen production, ultimately leaving behind a newer and tighter layer of skin. CO2 laser resurfacing is considered one of the most effective treatments for those with wrinkled skin.
