  • Patent number: 5782857
    Abstract: A wrinkle removing device comprises, inside a holding body and a sole under the body, a heating resistor for heating the sole, thermostat for temperature controlling the sole in a predetermined control cycle, a motor for producing vibrations and an electrical circuit. The electrical circuit includes the heating resistor, the thermostat and the motor, and is supplied with alternating current to power the heating resistor and the motor, in each case during at least one half-wave of the alternating current throughout the control cycle. With this device, an action of gentle massage of the face is combined with an action of sliding of the heated sole over the face, without producing disagreable variations in the speed of the vibration motor.
