Frequency 35---47 KHZ. This system, incorporating all the latest technologies in only one system, that includes cavitation fat-breaking technology, high intensity focused ultrasound, low frequency ultrasoinic slim, respresenting the top level in the Beauty field. Working Principle HIFU High Intensity Focused Ultrasound(3MHz). It relies on the basic concept of ultrasound. By focusing, high intensitied and continuous wave ultrasound will be generated;the temperature arising from this will selectively make the fat tissue liquefied without influecing the surrounding tissue and blood vessels. Outer package: Good Honeycomb carton inner package: PE Foam.
