PURPOSE: A high frequency generating device for skin care is provided to effectively generate high frequency through a digital control mode. CONSTITUTION: A high frequency generating device for skin care comprises a main controller(310), a drive voltage supplier(320), a high frequency generation controller(330), and a high frequency generation unit(340). The main controller provides a control pulse to the drive voltage supplier. The drive voltage supplier generates DC drive voltage and provides the voltage to the high frequency generation unit. The high frequency generation controller outputs a high frequency control signal, converts the DC drive voltage, and outputs high frequency signal of a fixed frequency. The high frequency generation unit generates a high frequency signal based on the DC drive voltage and high frequency control signal.
