A handheld apparatus including an internal motor and a removable treatment paddle. The removable treatment paddle is designed for connection with the internal motor, and typically has a first surface and a second surface. The first surface typically includes an abrasive material formed into or attached to the surface for skin exfoliation, and the second surface is typically a relatively less abrasive surface than the first surface, for aid in infusing at least one topical active into the skin after treatment with the first surface. The improved device also includes a multi-sided handpiece having a plurality of flat sides for ease of handling, and at least one ventilation hole to prevent overheating of the device during operation. The handpiece can also include a fan for proper ventilation through the ventilation holes. In one embodiment, the handpiece includes an insulating sleeve to protect the user's hand from the heat generated from the device, as well as to provide an improved gripping surface for the handpiece and to decrease the level of noise production from the handpiece.
