The CO2 laser emits a wavelength of light which gently heats the skin and evaporates skin in a controlled manner there and stimulating new skin and also production of collagen – a protein that improves skin appearance. The water within the skin cells absorbs this type of wavelength, resulting in the removal of thin outer layers of skin (epidermis) and heating of the underlying skin (dermis), which stimulates the growth of collagen – a protein that improves skin appearance. CO2 laser resurfacing can be used to address fine lines and wrinkles, moderate to severe lines and wrinkles, discoloration (including sun damage and age spots), acne scars, stretch marks, surgical and burn scars, and uneven skin texture on the face, neck, and chest. It can also treat benign skin growths like enlarged oil glands (sebaceous hyperplasia), xanthelasma, warts, and some skin cancers. Dr. Rokhsar was trained by the inventor of the CO2 laser, the late Richard Fitzpatrick, MD. He is considered an international authority on laser skin resurfacing procedures such as the CO2 laser and Fraxel laser and has spoken on this subject all over the world.
