How many HIFU treatments are necessary?

Ultherapy is the only FDA cleared HIFU (High Intensity Focused Ultrasound) device for noninvasive skin lifting. It usually requires one session then it is best to wait a few months before determining if more are needed. If it is not Ultherapy then it is probably not true HIFU but non-focused ultrasound or a much lower energy device.

Dear Sally:The issues you describe generally require a full-face treatment with Ultherapy.  While the number of lines recommended is good, I would generally deliver 800 to 1200 Lines with one treatment, offering a lower price to a younger person such as yourself who should need a lower number of lines. There have been no studies of fractional treatments such as what is being recommended, and I cannot imagine the advantage to you. Most patients would prefer to have the complete treatment up front, for earlier results and efficiencies in time and travel, and probably cost (I offer additional lines at cost), and if you are taking an oral medication to prevent discomfort, you will have more time for the effects to wear off if you have all lines with that first treatment.Ultherapy should absolutely be overseen by a physician. In my opinion, at least, it is not a procedure that should be offered in a spa setting.  You should determine whether they are offering HIFU with a device by Ulthera, or some other nonapproved device. I will be answering questions, offering free consults and a few lines of treatment for those who are interested in learning more and seeing what it feels like, on the 25th.All the best,  Dr. Clark

Hello Sally
Is the HIFU device FDA approved? does it have research that shows this unit  is a safe treatment? Does it have research to show it works? As your provider to provide proof. Do not confuse HIFU with MFUS (Ultherapy)
Know what you are buying? different units are not comparable, which is probably why you are reading variable advice on the internet.
