Abstract: A facial mask for use in effecting toning of a wearer's facial muscles includes two spaced layers of flexible sheet material secured together along their outer margins, and a quantity of freely movable particles of a filling material in the space between the two layers. When the mask is to be worn, suction is applied to the space between the two layers in order to effectively rigidify the mask according to the configuration of the wearer's face. The mask is pressed against the wearer's facial muscles by pressurizing an expansible chamber engageable with the back of the wearer's head, and/or by pressurizing a chamber formed by the flexible sheet layer wall and a front rigid wall.

Abstract: A facial mask for use in effecting isometric toning of facial muscles comprises a plurality of shaped pressure applicators located to overlie the termination points of selected facial muscles, and an expansible chamber located such that when the chamber is expanded, it causes the pressure applicators to apply pressure to the termination points of the selected facial muscles. The facial mask may further include a mouthpiece to be received in the user's mouth and to be bitingly engaged by the user's teeth for anchoring the user's mastication muscles and for tensioning the user's facial muscles around the lips during use of the device. The pressure applicators may also include surface electrodes for sensing EMG (electromyogram) signals produced by the muscles to provide an indication of whether the proper muscles are being exercised.
