Thermage has been around for much longer than Ulthera, but even with new advanced CPT technology, I have already found that the Ulthera, known to penetrate deeper than thermage, has provided patients, in general, greater satisfaction. This comes from the mouths of patients who have had both. On RealSelf.com patients have self-rated Ulthera with an 89% satsifaction rate vs. below 50% with Thermage.
I do know of many doctors who have virtually replaced their facial Thermage treatments with Ulthera. Of course, being newer, we are still learning as to how to best treat our patients with Ulthera. For the body, at this time, until other transducers are developed, I like the Theramage for the body better than ultherapy as the former is more effective with a larger surface area being treated.
