Do fat freezing and cavitation machines work?

Do the fat freezing and cavitation machines get cold enough to actually work? Will the ones in salons work or does it have to be in a doctor's office. The salon ones I've seen cost around $900 which is cheaper than the doctor's office ones.

Generally these noninvasive modalities are effective for only mild lipodystrophy and in patients with good skin quality.  It will almost always require several treatment sessions to reach a satisfactory endpoint.

In general, any of the fat cryo (freezing) treatments will give you a 10-20% improvement at best. They do not improve skin quality. They can be helpful in the right case, but in my experience are often used in the wrong clinical situation, resulting in disappointment.
