Abstract
One form of the device is a standard handpiece having a series of interchangeable treatment heads. The handpiece can accept cooperating treatment heads for twist-locking therein or by other engagement arrangement. The treatment heads may or may not have an internal motor assembly within them to create vibratory motion in the assembled device. The groups of possible treatment heads include LED-light-emitting heads, microcurrent-emitting heads, a treatment head having an abrasive or pebbled surface, as well as a bristle brush head. In another version, the handpiece and treatment head are integrated and not exchangeable. In this second version, a combination LED-light-emitting outer ring surrounds a central dual-lobe massage surface. The dual-lobe massage surface may be made from an inert material such as silicone, or it may be metallic in order to provide emission of therapeutic microcurrents.
