Dermabrasion is a skin-resurfacing procedure that uses a rapidly rotating device to sand the outer layers of skin. After dermabrasion, the skin that grows back is usually smoother and younger looking.Dermabrasion can decrease the appearance of fine facial lines and improve the look of scars, such as those caused by acne. Dermabrasion can be done alone or in combination with other cosmetic procedures.During dermabrasion, your skin will be numbed with anesthetics. You might also have the option of taking a sedative or using general anesthesia, depending on the extent of your treatment.Skin treated with dermabrasion will be sensitive and bright pink for several weeks. The pinkness will likely take about three months to fade.
