A dermabrasion hand tool for abrasively removing a skin surface by mean s of an abrasive stream projected onto the skin surface to be removed. The han d tool includes an elongated manipulative body having a longitudinal axis and first and second opposite ends. The hand tool also includes an operative head through which the abrasive stream is projected onto the skin surface to be removed a nd through which the removed skin surface and used abrasive stream are evacuate d, the operative head being removably mounted onto the first end of the manipulative body. The hand tool further includes a supply channel for supplying the abrasive stream to the operative head from a supply stream source, and an evacuating channel for evacuating the removed skin surface and used abrasive stream fro m the operative head to an evacuating means, both of said channels extending within and along the manipulative body and each having first and second extremities located respectively at the first and second ends of the manipulative body. The hand tool is characterized in that its operative head has a projection head for projecting the abrasive stream orthogonally to the skin surface to be removed; an evacuation chamber operatively connected to the evacuating chann el for facilitating evacuation of the removed skin surface and used abrasive stream into the evacuating channel; and rotation-inducing mechanisms for giving a rotational pattern to the abrasive stream projected from the operative head. The hand tool enables a controlled and adjustable removal of superficial skin surface. Furthermore, the hand tool enables a substantially even skin abrasion patter n, both in surface geometry and in time. Moreover, the hand tool enables to project and retrieve the abrasive stream to and from the skin surface to be removed in a rotational pattern and orthogonally thereto. The hand tool is also easy to assemble, easy to use, and easy to maintain.
