PURPOSE: An ultrasonic skin massage apparatus is provided to generate ultrasonic waves of 3Mhz for face massage and 800Khz for body massage at the same time, to simplify the structure thereof, and to improve the convenience of use. CONSTITUTION: The ultrasonic skin massage apparatus having a DC power source(1), a main switch(10), a time controller(20), a switching transistor(Q1), and a duty controller(30) additionally comprises an ultrasonic oscillation part(40), and a current level setting part(50). The ultrasonic oscillation part is switched on by receiving a pulse from the duty controller to output low frequency ultrasonic waves(800Khz) or high frequency ultrasonic waves(3Mhz). The current level setting part sets the level of current to adjust the strength of the low frequency ultrasonic waves or the high frequency ultrasonic waves.
