Aluminum Oxide Crystals or as we call them Diamond Dust are the perfect abrasive medium for microdermabrasion. Because it is inert, it does not cause any skin reaction. It is a hard, stable, crystalline sand-like material, making it the perfect exfoliant. It has the additional benefit of being absorbent. Each particle strikes the skin, performing a gentle, precise exfoliating action, absorbs surface oil and is gently washed away.
