CO2 lasers produce light at a 10,600nm wavelength, which is absorbed by water in the tissue. The laser energy heats up the water until it reaches a boiling point causing the evaporation of the affected tissue. Some heat is absorbed by tissue, causing tissue coagulation as well as thermal stimulation of deep skin layers, which induces fibroblast stimulation and neocollagenesis (the formation of new collagen).
In general, laser resurfacing is a method of reducing wrinkles, scars and blemishes. By using a laser to remove the outermost surface of the skin, laser resurfacing offers the skin a chance to regrow into a glowing, unblemished surface. Laser resurfacing also Wrinkles are filled in to get a smoother appearance.
