The device is very nice and useful for back pain and many other things, and it's simple to use. It's a new use, used a few times. Professional 5-in-1 Cavitation and Radiofrequency Ultrasound Device. A 5-in-1 multi-functional device that combines cavitation, ultrasound, and radiofrequency technologies, suitable for professional use. This device is ideal for beginners. Everything you need and much more, with the best return. The 5-in-1 Radiofrequency Ultrasound unit includes: * 1 x Body Multipolar Radiofrequency Head * 1 x 40KHz Head, 40KHz Cavitation Head * 1 x Suction Bipolar Radiofrequency Head * 1 x Facial and Eye Tripolar Radiofrequency Head (approx. 1) * 1 x Facial and Body Quadrupolar Head Specifications: Bipolar cavitation in ultrasonic and radiofrequency fat suction. 40000Hz (40KHz) for maximum speed vibration and the production of numerous vacuum air pockets inside and outside fat cells. It strongly affects fat cells to generate an internal explosion and break down triglycerides into glycerol and free fatty acids. 1MHz radiofrequency waves are used to drain integrated glycerol and free fatty acids through the enterohepatic circulation. Performance and Effectiveness Finally, the radiofrequency and suction energy pole is used to position and tighten fat. In physics, this is known as "cavitation." The internal explosion of micro-pores inside and outside cells can enhance molecular movement and increase energy levels. This will ultimately lead to the rupture of fat cells, thus achieving body-building and weight-loss effects. Applications and Benefits: 1. Dissolves fat, improves lymphatic fluid drainage, tightens skin, and improves its elasticity. Negative pressure radiofrequency fat suction head: By combining it with the latest radiofrequency technology, the device can directly reach deep fat deposits and enjoy the advantage of precise radiofrequency positioning. In a state of rapid activity, adipose tissue cells can generate frictional heat, increase local temperature, and eliminate excess fat and toxins from the body through the sweat glands, enterohepatic circulation, and lymph, ultimately achieving the effect of fat dissolution. Furthermore, thanks to the depth control technology, diamond particles of various sizes can contact the skin along its pattern, adjust the suction power through vacuum extraction, and rub with strong negative pressure to directly exploit thick fat. Therefore, the effects are very clear: improved circulation, accelerated fat breakdown, elimination of waste, enhanced cellulite removal effect, effective improvement of the nipple surrounding tissue condition, elimination of stubborn fat, and improved absorption of diet.
