Description

Beauty equipment system through ultrasonic phase control {SKIN CARE EQUIPMENT SYSTEM USING ULTRASONIC PHASE CONTROL}

An embodiment of the present invention relates to a beauty device system through ultrasonic phase control.

Wrinkle refers to a phenomenon of skin aging caused by degeneration and atrophy of elastic fibers, bonded fibers and muscle fibers in the dermis, or due to changes in elasticity due to aging of the skin caused by a decrease in moisture or subcutaneous fat. .

Wrinkles belong to physiological phenomena according to age, but the degree of wrinkles may vary from person to person depending on internal conditions or external factors of the human body. In general, it is known that the elasticity and elasticity of the skin is due to the network shape of collagen fibers and elastic fibers, and when the elastic fibers weaken or the production of collagen decreases, the elasticity is weakened, resulting in wrinkles.

The traditional method used to remove wrinkles on the skin is to apply cosmetics to the skin, but the effect is insufficient.

Therefore, in recent years, an ultrasonic treatment device has been proposed that has the effect of applying ultrasonic waves to the skin to stimulate the skin to remove wrinkles, remove waste products, and make the skin elastic.

Wrinkle removal using ultrasound may be performed using a probe that generates high intensity focused ultrasound (HIFU).

In general, a human body consists of a skin layer, a dermal layer, a fat layer, a muscle layer (Superficial Muscular Aponeurotic System), and a muscle, and focused ultrasound can generate thermal coagulation at a predetermined point in the muscle layer.

Specifically, in the process of generating thermal coagulation of a certain size in the muscle layer in a dispersed form and then regenerating the thermally coagulated portion by the peripheral portion of the thermal coagulation, skin wrinkles may be removed.

Wrinkle removal apparatus using such an ultrasonic wave does not leave a trace on the outside and has the advantage of being able to return to daily life immediately after the procedure.

However, the existing skin beauty devices using ultrasound had a problem that the technical completion was very lacking in terms of determining quantitative mechanical performance index based on clinical mechanism and efficacy analysis, determining adequacy, and analyzing effectiveness based on preclinical and clinical protocols.

For example, conventional skin care devices are limited in uniform output using a voltage control method, so that the ionization effect is insufficient, expensive, and user convenience is insufficient.

In addition, conventional skin beauty devices using ultrasound have commercialized equipment capable of performing Sonophoresis (20Khz~40Khz) in various frequency ranges, but there are technical limitations such as high-speed ultrasound output control, and accordingly, the performance output is weak and the effect is insufficient. There was a problem of causing pain and discomfort in the subject to be treated due to the occurrence of the image.
