Thanks for your question - many potential patients; and us doctors too, can get confused by all different devices out there and their claims. The following is my totally biased opinion, based on years of experience. First of all, there is no non-surgical fat reducing device on the market that comes close to liposuction with respect to permanently removing fat. That's a given. Looking at all the devices out there, you can lump them into different categories. All of them, except CoolSculpting, use an energy source to produce heat in the fatty tissue layer. Some use laser energy (like SculpSure), some use radio-frequency (RF) energy (Thermi, Exillis, BodyFX), some use ultrasound (Ultherapy), and some use a combination of energy sources (TruSculpt 3D). Some of these companies have conducted research to prove that they cause death of fat cells and some have not, but they all do produce lasting results. The problem with all of them, is that those results may be variable from one patient to the next and even from one body part to the next in the same patient! The other problem is that none of them are cheap. They are all less expensive than liposuction, by a little, but the results are not at all as dramatic. On the positive side, they are all non-surgical; therefore, the risks are substantially less and the recovery time is nearly non-existent. I cannot answer you specifically regarding BodyFX, because I do not have experience with that device. I do have experience with SculpSure, CoolSculpting, Thermi250, ThermiTight, Thermage, Venus Legacy, VelaShape, Viora Reaction, and Exillis. The market leader is probably CoolSculpting, but Sculpsure gets equivalent results with a lower complication rate and faster recovery time. I have evaluated TruSculpt 3D and I would expect that that device would also get very good results. I was not impressed with any of the earlier RF devices (Thermage, et al), as results were all over the map and the last thing I or any doctor wants is a line of folks at the front desk wanting refunds. The best advice I can give you is to go to a legitimate establishment with the proper medical oversight and ask the physician or NP to show you some before-and-after pictures of patients using that device. Also, be sure that the device in question actually states that it gets fat reduction. Some of these devices do not get the heat down deep enough and really only result in skin tightening. I recommend CoolSculpting, SculpSure, or TruSculpt 3D, but there are many others that may work as well.
