A Handheld Motorized Facial Brush Having Specialized Torque Transfer Clip. The heads interface with a conventional handpiece so that the facial brush or other facial treatment head can be removed and replaced with a head chosen from a group of treatment heads. The handpiece has a sealed, washable head portion that can be activated to rotate. Each treatment head or treatment assembly includes a torque transfer clip that provides biasing force between the handpiece and the head, but at the same time results in additional vibration being transferred from the vibration generator in the handpiece to the treatment head. The torque transfer clip also allows for some flex between the treatment head and the handpiece.
