Dermabrasion is a procedure to smooth the outermost layer of skin in order to promote new skin growth and improve appearance. Dermabrasion is done by a dermatologic or plastic surgeon using a dermatone, a handheld instrument with a swirling wire brush that scrapes away skin irregularities such as acne scars.
A local anesthetic and sedative are usually given before the procedure. Sometimes general anesthesia is used. A numbing spray may be used along with, or in place of, a local anesthetic. Dermabrasion is often done in stages, treating parts of the face at different times.
