My practice has completed well over a thousand CoolSculpting sessions. I can a say that with very few exceptions, they all loose volume due to the treatment. The amount of fat reduced varies with patients, but I think of the volume reduction to be nearly the size of a stick of butter. So if you can imagine your unwanted fat as multiple butter sticks, you can get an idea of how many sessions you might require. CoolSculpting works best with fit patients who want to loose discrete areas of fat in localized areas. I don't recommend it for obese patients (they won't see it) or generalized fat deposits (where do you stop). Is liposuction more effective, yes! But liposuction has multiple hassles and requires some recovery, not to mention the risks. CoolSculpting has very few risks, and little discomfort. You can eat your lunch during the session, but it might be a little ironic to eat the fat back. We can do additional treatments of the same areas as soon as six weeks but the final result may take three months.
