How does Cavi Lipo work? Ultrasound Cavitation + RF is a FDA approved, non-invasive procedure designed to reduce localized fat by applying safe levels of ultrasound energy via a hand held probe to a targeted area of subcutaneous fat. With Ultrasound Cavitation treatment, tiny micro-bubbles are created in the fat cells, which weaken the fat to liquify, releasing their contents to be reused or eliminated by the body, which are subsequently disposed of through the lymphatic and liver, leaving the healthy cells intact. It is also effective in reducing cellulite, a condition which affects most women over 20, whether slim or overweight. When applied in conjunction with Radio Frequency (RF), and fascia vacuum therapy, the heating and cavitation effects can also promote collagen realignment and as a result will tighten the skin and reduce dimpling.
