By controlling it, it becomes possible to perform an effective ultrasonic skin care treatment tailored to the user's skin type.

Hereinafter, each step of the method of controlling the ultrasonic skin care apparatus 100 according to the present embodiment will be described with reference to FIGS. 1 to 4 .

Details of the components having the same name as the components included in the ultrasonic skin care apparatus 100 as an embodiment of the present invention described above may follow the above.

In step 110, the first electrode 181 may deliver a microcurrent to the user's skin.

In step 120 , the second electrode 182 may receive a microcurrent that has passed through the skin.

In operation 130 , the calculator may calculate the impedance value of the skin based on the magnitude of the microcurrent.

The process of calculating the skin impedance value according to the above steps uses a Bioelectrical Impedance Analysis (BIA), which is a method of measuring the composition of the body by flowing a minute current through the body. , the economy is high.

Since the body contains water and fat, and fat contains almost no water with high conductivity, it has a large impedance value. By receiving the current from the second electrode 182 again, the calculator may calculate the impedance value of the skin based on the current.

In this case, the microcurrent may be an alternating current (AC).

In operation 140 , the determiner compares the impedance value with a reference value to determine a skin type including dry, neutral, and oily skin.

That is, the skin type may be divided into dry, neutral, and oily skin types according to the fat content of the skin, and thus the determiner may determine the skin type through the impedance value of the skin calculated by the calculator.

Here, the skin type may be further classified into very dry, dry, dry, neutral, medium, oily, or malignant.

In step 150, the controller may control the ultrasound treatment mode according to the skin type.

Accordingly, it is possible to further improve the skin beauty effect by irradiating the LED light to the skin in addition to the ultrasound transmission to the skin. More specific details related to the LED unit 170 and the LED light will be described later.

After the step of controlling the ultrasound treatment mode (S150), the step of transmitting the microcurrent (S110), the step of receiving the microcurrent (S120), and the step of calculating the impedance value (S130) are performed again, so that the calculator performs the impedance value again. The step of calculating the change value of (S170), and the step of providing the skin improvement index to the user according to the change value by the index providing unit (S190) may be further included.

That is, the process of firstly controlling the ultrasound treatment mode and secondarily flowing a current to the skin in a state in which the ultrasound skin cosmetic treatment is completed may be repeatedly performed.

Accordingly, by calculating the change value of the impedance value before and after the primary ultrasound treatment mode control and providing the skin improvement index according to the value to the user, the user can determine the result of the treatment and whether to perform the additional treatment.

Prior to the step (S190) of providing the skin improvement index, the step (S180) of the input unit receiving the satisfaction index for the ultrasound treatment mode from the user is further included, and the step of providing the skin improvement index (S190) includes the change value and A skin improvement index may be calculated by analyzing the satisfaction index.

In other words, as described above, by adding and analyzing the satisfaction index for the ultrasound treatment mode input from the user together with the change value of the impedance value, and calculating the skin improvement index through this analysis, the reliability or accuracy of the skin improvement index can be increased as described later. can

In this case, the input unit may be provided in the handpiece 110 , and more specifically, the above-described input unit may include a display 113 and a manipulation unit 114 .

In addition, the input unit may be a user terminal such as a smart phone interworking with the device.

More specifically, the step of providing the skin improvement index (S190), when the change value exceeds the reference value, by the index providing unit calculating the skin improvement index by adding an added index according to the change value to the satisfaction index (S191), and When the change value of the index providing unit is less than or equal to the reference value, the step of calculating the satisfaction index as a skin improvement index (S192) may be included.

In other words, since the satisfaction index input from the user is somewhat subjective, if the change value exceeds the standard value, the added index given according to the size of the change value is added to the satisfaction index, and in the opposite case, no additional index is added. Accordingly, the objectivity of the skin improvement index can be further improved.

After the step of providing the skin improvement index (S190), when the skin improvement index is less than the reference index, the adjusting unit may further include the step (S200) of adjusting the ultrasound treatment mode.

When the skin improvement index does not meet the reference index, it can be seen that the result of the pre-controlled ultrasound treatment mode is not satisfactory. You can set the ultrasound treatment mode.

After adjusting the ultrasound treatment mode (S200), when the skin improvement index is greater than or equal to the reference index, the adjustment unit maintains the ultrasound treatment mode (S210), and the input unit performs additional ultrasound treatment according to the ultrasound treatment mode to the user A step (S220) of receiving an input whether or not to do so may be further included.

That is, when the skin improvement index is equal to or greater than the reference index, it means that the result of the pre-controlled ultrasound treatment mode is satisfactory.

That is, the process of calculating the impedance value by secondly flowing a current to the skin through the measurement unit 180 in a state in which the skin cosmetic treatment using ultrasound and LED light is firstly completed may be repeatedly performed.

Accordingly, by calculating the change value of the impedance value before and after the procedure and providing the skin improvement index according to the value to the user, the user can determine the result of the procedure and whether to perform the additional treatment.

An input unit for receiving an input of a satisfaction index for a procedure from a user is further included, and the index providing unit may calculate a skin improvement index by analyzing the change value and the satisfaction index.

In other words, as described above, the reliability or accuracy of the skin improvement index can be increased by adding the satisfaction index for the procedure input from the user together with the change value of the impedance value as described above and calculating the skin improvement index through the analysis. .

When the skin improvement index is less than the reference index, an adjustment unit for adjusting the frequency of ultrasound and the wavelength of LED light may be further included.

If the skin improvement index does not meet the reference index, it can be seen that the provided results for the frequency of the ultrasound and the wavelength of the LED light are not satisfactory. It can give a great satisfaction to the operation.
