Abstract
A skin massage device for both massaging skin and applying a cosmetic product through retractable protuberances on the massaging surface. A first plurality of the protuberances are retractable into the massing surface, and include a piston with an outlet opening in its exterior side. A rod affixed to a housing in the massaging surface is engaged by the piston and this seals the opening. Upon massaging pressure applied to an annular bead on the piston, the piston is retracted into the massaging surface, opening the piston opening and permitting exit of cosmetic product. The piston extends into a housing supported at the massaging surface and the housing communicates into the reservoir for being filled. The piston includes a side wall which blocks communication between the housing and the reservoir when the piston is retracted, whereby cosmetic product in the housing is forced out the opening in the retracted position of the piston.
