The present invention relates to a skin care treatment device, and more particularly, to a skin care treatment device capable of supplying high frequency energy to a wider area of the skin by using a three-phase radio frequency.

The skin has not only a physiological function of protecting the body but also a social function of expressing an individual's appearance, emotions, and the like, and in recent years, interest in skin beauty has been increasing.

Skin care mainly focuses on the prevention and treatment of so-called skin aging such as wrinkles, pigmentation, pigmentation, drying, and reduced elasticity, and can be divided into surgical and non-surgical methods.

Among them, the non-surgical method has the advantage of not adversely affecting daily life and having fewer side effects. A representative method is a method using a high frequency of RF (Radio Frequency) band. The application of high-frequency energy to the skin is known to enhance the elasticity of the dermal layer and increase collagen synthesis, thereby improving wrinkles.

The high frequency skin care device basically includes a high frequency generating circuit and electrodes in contact with the skin, and the types thereof vary depending on the number of electrodes and the type of the high frequency generating circuit.

However, even when the electrode pairs of E1-E2, E2-E3, and E3-E1 are sequentially operated, there is a limit to widening the treatment area because the RF energy supply area is limited during any one cycle.

Second, using the multiplexing switching unit SW as described above, the overall structure and operation method are complicated. That is, in order to satisfy various combinations between the RF generating units G1, G2 ... Gn and the electrodes E1, E2 ... Em, a multiplexer or a plurality of relays must be used, which causes the multiplexing switching unit SW The structure and driving method is too complicated, especially when using a relay, there is a problem that the product life is greatly shortened.
