Methods and apparatus for removing skin blemishes and wrinkles by abrasion using a burr are disclosed. In one example a hand-held device (10) is used. It has a body (11) into the proximal end of which a low-voltage motor (14) is removably clipped and onto the distal end of which a shield or fitment (12) is removably attached. A rotary burr (20) is located within the shield so as to be rotatably coupled to the motor shaft. Preferably, the burr (20) and the shield (12) are attachable and removable as a single-use disposable fitment. The shield (12) may be located off-center with respect to the burr (20) so that rotation of the shield with respect to the body (11) will to expose more or less of the burr. A slot (32) may be formed in the wall of the shield (12) to discharge skin debris onto the skin being treated where it can be wiped away.
