A novel handpiece and system for abrasion of skin is disclosed. A short handpiece (31) with a threadably movable tip (32) is used. The opening (35) in the tip (32) is centered on the handpiece (31) axis and a small diameter particle input channel (30) and diameter larger output channel (34) are both offset from the handpiece axis. A central blade is integral with the tip and divides the tip into two volumes which each communicate with the opening and respective ones of the input and output nozzles. 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 (42) supported within a support can (41). The annular area between the can (41) and filter (42) is connected through a secondary emergency filter (55) to a vacuum pump (60). The cylindrical filter (42) can be a flexible filter bag. A large source (20) of abrasive particles (21) is coupled to the handpiece inlet and the filter is coupled to the handpiece outlet.
