My personal experience with 6 sessions of ultrasonic fat cavitation, called "the non invasive liposuction".
It didn't do anything for me, personally. I had the sessions and exercised afterwards, drank lots of water and didn't overeat or eat junk. I'd say it has potential for noticeable results if you have a SMALL amount of fat in the area, but not a large amount like I have on my abdomen. Also I wonder about the safety of a prolonged ultrasound in that area (over the ovaries as well). They say the frequency only targets fat cells but I never fully trust these things. I might try it again in the future when I only have a smaller amount of fat left that exercise won't target.
