A method for making micro-abrasions on human tissue comprising placing a handle having an open chamber therein on human tissue to close said chamber, applying suction to said chamber to sealingly engage the periphery of the chamber with the human tissue and partially sucking the human tissue into said chamber, inducing the flow of air into the chamber by the removal of air from the chamber by suction while restricting entry of ambient air from the surrounding atmosphere into the chamber around the periphery of the chamber, entraining a reducing substance in said flow of air prior to entry of the flow of air into the chamber, directing the reducing substance entering the chamber against the human tissue at an angle less than 90 DEG , entraining used reducing substances and abraded tissue in the flow of air being removed from the chamber by suction and collecting used reducing substances and abraded tissue in a manner to prevent reuse of the reducing substances during continued application of a vacuum to the chamber.
