The science behind Cavi-lipo.. High frequency ultrasound wave stimulates and vibrates the fat cell at such a high rate it causes tiny air molecules to form that are negative in pressure. These tiny air “bubbles” force their way out of the cell and by doing so burst the fat cell. That same ultrasound wave passing through the surface skin stimulates and oxygenates the surface cells causing a firming and tightening of the skin. The Cavi-Lipo system reduces fat cells, improves cellulite, tightens skin and improves lymphatic drainage. The FDA has cleared Cavi-Lipo for use in the USA.
