CO2 laser resurfacing is a non-surgical cosmetic procedure that uses a carbon dioxide laser to improve the appearance of the skin on the face. The procedure works by removing the outer layer of damaged skin, stimulating the production of collagen and new skin cells, and reducing the appearance of fine lines, wrinkles, age spots, and other skin imperfections. CO2 laser resurfacing is an effective treatment option for patients who want to improve the overall texture and tone of their skin.  CO2 laser resurfacing is particularly effective for reducing the appearance of fine lines and wrinkles around the mouth area.  For deeper lines or more significant skin damage, a second treatment may be necessary to achieve optimal results. It is important to note that CO2 laser resurfacing is a relatively invasive procedure, and it may not be suitable for all patients, particularly those with darker skin tones or a history of skin conditions. A board-certified plastic surgeon can provide more information on the benefits and risks of CO2 laser resurfacing and help patients determine if it is the right option for their individual needs and goals.
