Ablative lasers, such as a CO2 laser, work by traumatizing the skin. It removes the thin outer layer of skin (epidermis) and heats the underlying skin (dermis). This stimulates the growth of new collagen fibers. As the epidermis heals and regrows, the treated skin appears clearer, smoother and tighter. Co2(Carbon dioxide) laser resurfacing is used to treat a variety of skin conditions like wrinkles, photodamage, scars, warts, birthmarks and enlarged oil glands on the nose. Co2(Carbon dioxide) lasers very precisely remove thin layers of skin with minimal heat damage to the surrounding structures.
