Dermabrasion for Acne
Dermabrasion is done in an office or outpatient facility. Sedatives may be used to decrease anxiety, and topical anesthetics are applied to lessen discomfort. During the procedure, a rotary abrasive instrument (a rapidly swirling wire brush, diamond cutting tool, or sandpaper) is used to remove or sand under the layers of the skin to remove irregularities. Afterward, soothing ointments are applied.
After dermabrasion, the sensation is similar to that of severe sunburn. However the doctor can prescribe medication to alleviate discomfort, and most people resume their normal activities within 7 to 10 days of the procedure. Good hygiene and the regular use of moisturizing lotions help speed healing. Eventually a new layer of skin forms, giving the skin a smoother appearance. At first, the newly formed skin tends to be lighter than the original skin tone. The pink or lighter skin gradually fades, and skin returns to normal color in 8 to 10 weeks. Makeup can be used to hide redness in the meantime. Exposure to sunlight should be avoided for 3 to 6 months after dermabrasion; sunscreen must be used whenever going outdoors. Complications of this procedure are rare but may include pigment changes, thickened skin, and fever blisters in people prone to herpes infections.
