Microdermabrasion is a safe, minimally invasive, in-office procedure used to gently exfoliate skin. Using vacuum-assisted suction, the skin is rubbed with an abrasive particle such as fine, powdery aluminum crystals or small diamond tips. Microdermabrasion assists in removing the excess keratin and outer layers of the epidermis in a controlled manner. As with other treatments for keratosis pilaris, the reports on this procedure are anecdotal and from small group observations. Instead of in-office microdermabrasion, another option is in-home personal exfoliation with a loofah sponge or a commercially available pad such as Buf-Puff. Newer available home therapies include gentle exfoliation with vacubrasion (fine diamond abrasives) home microdermabrasion systems. Often, vacubrasion and other skin vacuuming procedures combined with retinoid creams over the counter and lactic acid lotions are very effective in controlling keratosis pilaris.
