Abstract: A device for working a conditioning substance on a surface comprises a body portion containing an activatable motor. A head attached to the body portion has an outer head and a rotatable inner head. A drive shaft extends between the motor and the head, and is driven by the motor. The drive shaft has a first drive take off for imparting rotation to the inner head about a first central axis of rotation passing through the inner head. The drive shaft also has a second drive take off for imparting rotation to at least one massaging element about a second axis of rotation passing through the massaging element by frictionally engaging the massaging element, each massaging element being located within the inner head and extending past an outer surface thereof. When the motor is activated, each massaging element is simultaneously rotated in two manners, firstly, about the first central axis of rotation and secondly about the second axis of rotation, to work the surface upon the device being then applied.
