Laser Lipo Cavitation

What is focused ultrasound?
The wave of ultrasound concentrates into one point in subcutanerous fat layer tissue. Only the target tissue is acted while the surrounding structures remain intact. The metabolized contents(triglyceride, fatty acid) of cell will excrete outside body automatically through blood circulation and lymphatic drainage.

What is cavitation? 
It is a physical phenomenon associated with three aspects: formation, crowth, collapse of bubbles within the liquid of body due to the variations of local static pressure. 

What is the difference between ultrasound and focused ultrasound? 
Focus ultrasound is a highly precise medical procedure using high-intensity focused ultrasound to heat and destroy tissue more rapidly.
