Which is more effective for jowls, Thermigen Vs Ultherapy?

I have read the previous experts testimonies to the Ultherapy effect being better than the Thermigen RF treatments. If my colleagues took the time to fully understand these two therapies or treatments they would see these modalities are like comparing apples to oranges! One is "external", non invasive, applied to the skin surface while the other is minimal invasive. Yes with minimal invasion the skin is incised! These modalities address the skin/fat in such a different technologies. Than it is easy to see that in true expert hands the minimal invasive treatments of Thermigen RF can obtain excellent results in many body areas not just the face/neck as with the non invasive ultrasound, Ultherapy. If fact, Thermigen RF is being used to treat face, neck, under eyes, axillary fold, upper arms, breasts, abdomen, waist flanks, back, thighs, vaginal area offering impressive skin tightening and fat reduction of the sub dermal fat layer. In my hands I would offer the Thermigen to tighten the chin/jowls much over this external heating concept. But again that is my personal opinion. The test of time will be needed to demonstrate the ease of these therapies. Though I would recommend the prospective patient see doctor providers of both therapies.

Ultherapy is a deep focused ultrasound that does not require any use of needles. Thermigen is a radiofrequency energy that is delivered via a cannula through the skin after local anesthetic is injected into the area to be treated. Although there is no suction of fat, the technique of infiltration and then passing a cannula back and forth is similar to liposuction. Swelling and brusing might occur to a greater extent than Ultherapy, but I am not aware of any comparison studies between the two technologies.

Thermigen is relatively new and I have not been exposed directly to this device so I can not comment from personal experience. I am awaiting trusted colleagues of mine who may  have it to inform me of their results once enough months pass to see results and understand better the side effects.
