Which is better, Exilis Vs. Ultherapy?

Ultherapy can help lift facial sagging features without surgery by delivering focused ultrasound energy deeply and contract the supporting structures and induce collagen.  Exilis is not focused ultrasound energy that can liquify the fat cells to reduce bulk fat so the two devices are not to be compared.  Exilis may be compared with CoolSculpting, a device by Zeltiq that can recontour fat by killing the fat cells permanently and reducing the bulk of the fat bulge, while Exilis may liberate the fat from the fat cells and not provide long term reduction in fat cell numbers.

Thank you for this excellent question. Ulthera is a non-invasive focused ultrasound treatment that is designed to lift and tighten the tissue deep to the skin. Exilis is a radio-frequency device, designed to heat and tighten the skin. I think there is a lot of overlap with these devices and many patients can get good results with either one. Ultherapy typically cost more than Exilis because of the consumables used in the treatment.. There is no downtime with either Ulthera or Exilis, and the results should last about 12-18 months. I have had Ultherapy twice, and am happy with the results. The only down side with Exilis is that it requires a series of treatments. Good luck.

Thank you for this well thought through question.  I use both Ultherapy (which uses focussed ultrasound energy) and Exilis (which uses radiofrequency energy) in my clinic.  Exilis is a very good treatment and the best results are achieved over a course of treatments spaced at regular intervals. Ultherapy on the other hand only requires one treatment.  
In my personal experience Ultherapy will provide the patient with longer lasting results than Exilis but it also takes longer for the best results to be noticeable.  The results from an Exilis treatment can be noticed almost immediately.  Like many treatments, what is going to be the most preferred option for one patient may not suit somebody else.  
I would encourage you to have your treatment at a clinic that offers a range of treatment modalities so that you have the chance to find the treatment that is going to work best for you.   I would also encourage you to ensure that if you do decide to have treatment with Ultherapy, that the clinic is using the genuine Ultherapy system and not a generic 'focussed ultrasound treatment' that will not provide you with the same results.   I hope that this has been helpful and I wish you the best of luck with your results.  Dr Haus, London.
