Dermabrasion removes a layer of surface skin to improve the appearance of facial scarring due to acne, chicken pox, injury or other causes, as well as uneven pigmentation, wrinkles, sun damage, tattoos, age spots and certain kinds of skin lesions. The skin is frozen, typically with a spray, and then abraded with a high-speed rotary instrument for a dramatically smoother, fresher look. After the procedure it is normal to feel a sensation similar to sunburn for a week or so, at which time most patients are able to return to work. The newly revealed skin will likely appear pinker than usual for two to three months. Patients should be sure to adequately protect skin from sunlight.
