Abstract: Disclosed are a control method and device of a portable beautifying apparatus capable of being easily moved, beautifying the human face skin by galvanic ion current, far infrared ray, and vibration, and measuring the skin state. The control device includes: a microcomputer for controlling the whole operation of the beautifying apparatus; a key input part for inputting into the microcomputer an operation command selected by s user; a galvanic ion current output part for elevating a battery's power to a level and outputting galvanic ion current according to the control of the microcomputer; a galvanic ion current detecting part for determining whether or not the galvanic ion current output from the galvanic ion current output part flows onto the user's face skin; a vibration generating part for generating a vibration according to the control of the microcomputer; and a far-infrared ray generating part for generating a far-infrared ray according to the control of the microcomputer.
