Lipo Cavitation is a non-invasive procedure using ultrasound to break down fat from the body. This procedure is a good alternative if you seek fat reduction in areas associated with liposuction but are wary about going under knife. Unlike the surgical procedure of liposuction, lipo cavitation is an outpatient treatment with no anesthesia. It is typically painless (post-treatment side effects include mild bruising and temporary skin sensitivity).
