The present invention relates to a self-operational beauty device using an augmented reality image, and more particularly, when using a high-intensity focused ultrasound (HIFU)-based beauty device, an ultrasound irradiation point in the skin that is not visible to the naked eye is augmented reality (Augmented reality) Reality: It is to provide a self-operational beauty device using an augmented reality image that can visually check the procedure and the amount of ultrasound irradiation by matching with AR) images. The present invention is a power supply unit for supplying operating power to each component； An input unit for setting an operating environment of the device and switching whether or not the ultrasonic irradiation is operated； Beauty device control unit for controlling the overall operation of the device； A pulse generator for generating a pulse signal for ultrasonic oscillation and transmitting it to the HIFU oscillator； HIFU oscillator that is formed of a ceramic material, generates ultrasonic waves according to vibration, generates focused ultrasonic waves according to a pulse signal, and irradiates the skin； A skin beauty device comprising a first transmitting and receiving unit for wirelessly transmitting the pulse signal generated by the pulse generating unit to a display device； And a camera that captures a user's face to obtain an image. An image extracting unit for extracting a user's face shape from the image acquired from the camera； A second transmitting and receiving unit for receiving a motion pulse signal transmitted from the first transmitting and receiving unit of the skin care device； An image generator for generating a virtual spot image in response to the motion pulse signal received from the second transmitter and receiver； A coordinate generator for recognizing the location of the skin care device based on the shape of the user's face extracted from the image extracting unit and generating the coordinates； An AR image generator for e
