A novel handpiece and system for abrasion of skin is disclosed. A short handpiece with a threadably movable tip is used. The opening in the tip is centered on the handpiece axis and a small diameter particle input channel and diameter larger output channel are both offset from the handpiece axis. A vacuum control opening is formed in the tip for easy control by the operator. Abrasive particles and removed tissue are applied to the interior of a cylindrical filter supported within a support can. The annular area between the can and filter is connected through a secondary emergency filter to a vacuum pump. The cylindrical filter can be a flexible filter bag. A large source of abrasive particles is coupled to the handpiece inlet and the filter is coupled to the handpiece outlet.

1. Microdermal abrasion apparatus comprising:a supply container for abrasive particles; a handpiece for applying an input stream of abrasive particles to a skin surface through a first passage and for withdrawing a waste stream of abrasive particles and abraded tissue from the skin surface through a second passage; a connection line between the first passage of the handpiece and the supply container to provide the input stream of abrasive particles; a waste filter that is installable and removable for disposal as a complete unit, the waste filter being comprised of: an integral outer container; a filter inlet conduit releasably connected to the second passage in the handpiece; a filter outlet conduit for an air stream from which the abrasive particles and abraded skin have been filtered; and a filter element positioned within the outer container, and integrally disposable therewith, the filter element defining a boundary between a central volume therein and an exterior sealed volume between the filter element and the outer container; and a vacuum pump having a vacuum line releasably connected to the outlet conduit.
