As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
When the existing multi-electrode RF equipment is overlapped, electric fields formed by different electrode pairs attract each other, so that the radio frequency depth is insufficient, and the cosmetic effect is poor.
In order to solve the problems, an RF beauty instrument and an electrode current control method thereof are provided.

Blood, lymph and other tissue fluids in human tissues contain a large amount of water, and thus are good electrical conductors. In addition, the tissue fluid of human body contains a large amount of ions, such as Na + 、K + 、CL - Etc., and thus capable of conducting current, and ions move in the direction of the electric field lines under the RF high frequency current. During the positive half cycle of the RF high-frequency current, positive ions are pushed to the negative electrode, and negative ions are opposite; during the negative half cycle, positive ions are attracted to the positive pole, and negative ions are opposite.
Since the RF high frequency current has a very high frequency, the polarity is changed very quickly, and the ions move or vibrate back and forth sharply along the direction of the power line; the various ions, which differ in size, mass, charge and rate of movement, rub against each other and against the surrounding medium during vibration, generating heat.

By providing the positive and negative electrode pairs, the phase difference of the RF high-frequency current applied to the positive and negative electrode pairs is controlled so that the RF high-frequency current is the same in the direction of each positive and negative electrode pair. The RF current is formed by the movement of charged particles in the skin of a human body, according to the principle that like charges repel each other, the RF current in the upper layer pushes the RF current in the lower layer to the deeper part of the skin of the human body, so that the radio frequency treatment depth is greatly increased.
