Abstract: A micro-dermabrasion system and method in which a handpiece includes an axially aligned treatment orifice and laterally offset particle supply and waste removal channels. At least a portion of the particle supply channel is angularly offset relative to the waste removal channel so the particle stream impinges substantially on the center of the treatment orifice. The handpiece employs tapered couplers to permit easy attachment and detachment of particle supply and waste removal lines in a handpiece having a small diameter. The particle supply container is designed to be pre-filled by a supplier, and disposed of when empty without disassembly. The supply container is also constructed to permit controlled aeration of the particles before delivery to the handpiece to reduce clogging of the particle lines and to facilitate continuous adjustment of particle flow rate.
