CO2 (carbon dioxide) skin resurfacing  is the removal of the top layers of the skin via focused laser light energy. Some types of lasers also penetrate into deeper layers of skin to provide additional benefits. The main goals of CO2 skin resurfacing are to make the skin smoother, tighter, and more even in tone, texture, and color.  The best candidates for CO2 are light-skinned who are in generally good health and who have a positive outlook and realistic expectations about outcome.

Those who can benefit from a skin resurfacing procedure include patients with skin imperfections like wrinkles, loose skin, scars (including acne scars), vascular lesions (like broken capillaries), enlarged pores, rough skin texture, dark spots (hyperpigmentation) on the skin.
