I was told it was supposed to be uncomfortable but not painful. I had to pause several times and it was worse than getting tattooed even though Thermage only took 30 minutes. Felt like someone taking a match to the inside of my flesh. I would not get this done again even if I had seen some results. As it was, though, three months later and I see NO improvement. I have attached before/after photos. I did notice a little divet of missing fat from above my belly button after treatment. Minor but was really disappointed that the treatment did nothing.
