How does the 4D Cavitation work for fat reduction : 

The 4D Cavitation treatment head emits ultrasonic sound energy at 32-40kHz at two separate modulations, which penetrates the skin to a depth of approximately 8-9mm. This is just deep enough to reach the subcutaneous fat layer.
1. an innovative technology with 4 pieces of cavitation heads.
2. Each diameter is equal to 4.3 cm, covering a total surface of 58 sq.Cm.
3. 4th cavitation technology with integrative cavitation transducer.
4. Cavitation frequency Auto-Tracking technology.
