In the process of using medical beauty equipment for facial skin tightening and wrinkle removal, each beauty instrument is also equipped with matching beauty tools that can be directly used on the human face.

[0003] The Chinese patent with application number CN201920349776.2 discloses a beauty radio frequency probe with negative pressure, including a head, a handle and a hollow connecting tube fixedly connected at the bottom. The upper surface of the head is connected to a radio frequency electrode, and two electrodes are fixedly arranged at the lower end, which are electrically connected to the upper end of the wire respectively, and the lower end of the wire is electrically connected to the radio frequency system; a circular groove is arranged in the center of the head, a negative pressure hole is opened at the bottom of the groove, a filter layer is arranged in the groove, a fixing plate is arranged at the upper end of the filter layer, and a negative pressure hole is also opened on the fixing plate, the lower end of the groove is sealed and connected to the upper end of the negative pressure tube, and the lower end of the negative pressure tube is connected to the negative pressure system; the inside of the handle is a cavity, and a circular opening is opened at the bottom. The wire and the negative pressure tube are located in the cavity and extend through the circular opening to the connecting tube. During operation, the suction force generated by the negative pressure will pull the skin upward, and the effect of lifting, firming, and reshaping the facial contour line can be achieved without the beautician cooperating with the lifting technique, and the effect is better than manual lifting.
