A lightweight, handheld tool for performing cosmetic dermabrasion comprises a tool body, which is inserted into a disposable sleeve during use, which sleeve has an abrasive with an exposed grit adhered to at least a portion of the exterior, which abrasive contacts the surface being undergoing dermabrasion. The sleeve envelops the tool body, protecting the tool body from the transference of bacteria and particulates during dermabrasion, reducing the need for regular sterilization of the reusable tool body. After use, the disposable sleeve is readily discarded and can be replaced by a new sleeve for the next use.
