I went in for a general consultation about my facial shape, and they recommended Thermage, so I had it done. I went because it was supposedly famous by word of mouth, but the clinic was in a blue-lit, disorganized state, so I was a bit surprised at first. Also, the doctor was not particularly friendly and, for some reason, seemed rather proud... They said Thermage would reduce swelling and refine the face shape, but honestly, even right after it I still could not really tell. I paid out of frustration and left.
At the time I did not know, but the procedure itself is expensive and absolutely not something in the 200,000-won range. Anyway, I do not think I will ever go back.
