It works just like a professional microdermabrasion treatment without the hassle or cost. The hand-held device uses the same aluminum oxide crystals as the ten thousand dollar machines found at your doctor's office. It smoothes away dead skin cells, diminishing age spots and other signs of aging. The system includes 1 personal microderm, 5 exfoliating discs 2 green and 3 blue, 1 electric cord, 1 facial cap, 1 body cap, 1 reusable filter, instructional CD and pamphlet. For best results when using the Personal Microderm, use a gentle cleanser, toner, and cell renewal cream in conjunction with the microdermabrasion tool.
