The restraining portion 115 and the engaging portion 156 may be formed in various shapes. Since the second electrode body 154 is detachably coupled to the casing 110, various types of skin improvement modules such as a vibrating massage unit, a vibrating cleanser, and an ultrasonic generator can be used instead of the second electrode unit 153. It may be installed in a portion where the second electrode part 153 is installed.

The first electrode part 151 and the second electrode part 153 are formed by surface-treating a galvanic layer. The galvanic layer generates a change in current due to moisture or the like of the skin. Galvanic is a very weak current that repels the same poles and helps to penetrate skin improvement agents such as cosmetics into the skin. Therefore, it has the effect of improving the reddened skin caused by acne or blurring the melanin pigment such as melasma.

The skin measuring unit 150 further includes a vibration generating unit 159 installed on the second electrode unit 153 to vibrate the second electrode unit 153 . When the first electrode unit 151 and the second electrode unit 153 are energized by the skin and the body, the vibration generating unit 159 vibrates as current is supplied to the vibration generating unit 159 . Accordingly, the user can check whether the skin care apparatus 100 is continuously operated by the vibration generated by the vibration generating unit 159 by tactile sense. In addition, it is possible to stimulate the skin by the vibration of the vibration generating unit 159 to promote the absorption rate of moisture or oil.

The light irradiation unit 120 , the camera unit 140 , the communication unit 160 , the skin measurement unit 150 , etc. are electrically connected to the circuit board unit 170 .

A method of operating the skin care device according to an embodiment of the present invention configured as described above will be described.

The user presses the power button unit 112 and operates the mode conversion button unit 113 to select a camera shooting mode. When the camera shooting mode is selected, the circuit board unit 170 supplies power to the light irradiation unit 120 . At this time, the circuit board unit 170 controls the light to be irradiated from one LED 123 among the plurality of LEDs 123 . Next, it is controlled so that light is irradiated from the next LED 123 .

As the light irradiated from the LED 123 is scattered at various angles by the light scattering unit 133 of the light scattering unit 130 , a slightly dark lighting environment is created inside the light scattering unit 130 . At this time, when the barrel 130 approaches the skin, a dark part is formed in the pore or wrinkle of the skin, and a protruding or flat part becomes a bright part. Next, when the camera unit 140 captures the skin, the skin condition is clearly divided by the dark area and the light area, so that the skin condition can be clearly identified. Since the image captured by the camera unit 140 is transmitted to the electronic device by the communication unit 160 , the user can visually check the skin condition through the electronic device.

Next, the user applies a skin improving agent such as a moisture cream or oil cream to the skin. The user operates the mode conversion button unit 113 to select a moisture measurement mode or a moisture care mode. When the casing part 110 is held by hand, a finger or palm comes into contact with the first electrode part 151 located on both sides of the casing part 110 . Then, when the second electrode part 153 is brought into contact with the user's skin, the first electrode part 151 and the second electrode part 153 conduct electricity. At this time, as the skin improving agent is absorbed into the skin, a current change is generated in the skin, and the second electrode unit 153 transmits a signal related to the current change to the controller. The control unit transmits a signal related to skin change to the electronic device through the communication unit 160 , and the electronic device displays the amount of moisture, oil content, saturation amount, etc. of the skin according to the current change in a graph. Accordingly, the user can check the process of changes in the amount of moisture or oil in the skin in real time while viewing the graph.
