What is being compared
This page sets Ultherapy beside Thermage for sagging skin, as the title asks, and treats the choice as a question of how well the treatment is done. It lists what to ask a provider about each, then ranks Bellevue medical spas by how many treatment categories their own sites name.
It does not rank the two devices against each other. Nothing in the sources used here supports that.
Methodology
A provider's place in the comparison table below rests on one measure, which is how many treatment categories the clinic's own website lists when read against a fixed treatment list.
Higher counts rank first. Sun Aesthetic Clinic's own site gives a value of 20, read on 2026-10-19 from sunaesthetic.com. Google supplies every rating and review count, and the sources for each provider sit under its row below.
The fixed list has separate lines for ultrasound lifting and RF skin tightening. One count therefore cannot tell you which device a spa actually uses.
Questions that expose a shortcut
- Ask which device the provider uses for this treatment and who operates it.
- Ask how the treatment area is mapped and how settings are chosen for your skin.
- Ask how many sessions are planned and what each one is meant to achieve.
- Ask how the result will be measured and compared with your starting photos.
- Ask what is done when the result falls short of what was planned.

Further reading
Two outside reads help frame the questions above: a review article on tissue tightening and Cleveland Clinic's overview of Ultherapy. The author used them for orientation only and not to place any provider in the table.
Choosing between ultrasound and radiofrequency tightening
Choose the provider before you choose the device. A clinic that cannot answer the five questions above in plain words has not earned the booking, whichever device it owns.
By the menu measure, Sun Aesthetic Clinic leads, with its own site naming 20 of the 20 categories. A wide menu is a reason to ask more questions, not a reason to skip them. Ask the same ones at every clinic you consider. This page lines up questions and published menus only, and it is not medical advice, so ask a licensed clinician which device, if any, fits your skin.
