Abstract: The present invention relates to a portable HIFU skin care device. The portable HIFU skin care device (1) of the present invention is divided into three portions. Firstly, a main body (100) has a rechargeable battery embedded therein, a power button and a step button installed therein for adjusting the intensity of an ultrasonic wave, and a display for displaying the operation states of the device, including the number of shots. In addition, a cartridge (200) is used by being mounted on a head part of the main body (100) and has a HIFU transducer embedded therein. A cradle (300) has a charging part which is installed therein, is capable of charging by being connected with the cartridge (200) and an adaptor, accommodates the main body (100) through a placement groove while the cartridge (200) is mounted to the main body (100), includes a UV lamp for disinfecting the head part of the cartridge (200) when accommodating the main body (100), and charges an internal battery of the main body (100).

Abstract: A method of controlling an operation of a portable skin treatment device, the method including: if a control button of the treatment device is pressed, heating a heater to prepare heating of a tip of the treatment device in a predetermined temperature range; and if heating of the tip is completed, turning on a light source disposed inside a housing of the treatment device and performing light irradiation treatment of irradiating light onto the skin through the tip together with heat. By using the method of controlling the operation of the portable skin treatment device by applying heat to the skin area of a disease of sebaceous glands such as acne etc. or itch and by irradiating light onto the skin area, treatment effects can be improved, and the fact that a user is getting treatment can be more realistically recognized.
