Oh my goodness, go read some of the reviews here from people who had Thermage done: http://www.realself.com/skin_care/skin_treatment/thermage.html#reviews

I feel so bad for the ones who said they look WORSE and now their skin and underlying structure is completely damaged, sagging, etc.

I am sure there are some who had great results, but many seem to have no results (maybe they are the lucky ones) and bad results. I definitely wouldn't risk my face for it.
