ABSTRACT:
An improved ultrasonic wave cosmetic device which is able to protect skin against burns. The ultrasonic wave cosmetic device for treating skin includes a probe head having a skin contact metal surface for contacting the skin to transmit an ultrasonic wave thereto, an ultrasonic wave vibration element for vibrating at an ultrasonic wave frequency in response to an output signal from an ultrasonic wave oscillation circuit, and a temperature sensor mounted in a manner directly contacting a side surface of the ultrasonic wave vibration element and a surface opposite the skin contact metal surface for detecting the temperature of the probe head. The temperature sensor feeds back signals to the oscillation circuit which terminates the oscillation output signal when the probe head gets too hot.
