An electrical beauty appliance is provided to control the emission of ions, supersonic waves, and low-frequency waves through a micro-controller without overlapping individual operation signals. An electrical beauty appliance comprises: a power supply; an input unit; a micro-controller; a generation unit; and an output unit. The input unit includes a supersonic wave operation key, a low-frequency operation key, and an ion operation key such that a user selectively presses a desired operation key to generate an input key that is transferred to the micro-controller. The generation unit includes an ion generator, a low-frequency wave generator, and a supersonic wave generator. The output unit includes a display and a signal sound generator. The micro-controller includes a controller and a signal generator.
