The Body Kit consists of 1 small and 2 large Black discs (body only) and 1 small and 2 large Yellow discs (intense body). These discs are very coarse and are meant to be used on the body only. The PMD Personal Microderm uses a patented spinning disc technology to deliver revolutionary microdermabrasion treatments and unmatched, brilliant results. The patented disc spins as it glides across the skin and provides a beautiful treatment without having to manually scrub the PMD against the skin, which many other microdermabrasion devices require. Aluminum oxide is a naturally occurring element that is extremely hard, second only to diamond. These crystals are completely hypoallergenic and prevent the possibility of any allergic or adverse reaction. The aluminum oxide embedded discs provide the most effective results available, and they completely eliminate the possibility of spreading bacteria that may cause breakouts or irritations, which is a risk when diamond tips are used. Imported.
