Does thermage work on cellulite? I honestly have never heard of anyone being treated for cellulite with thermage.
Thermage is a procedure that's normally used for elasticity of the skin. A doctor will use radio waves and heat to damage the surface of the skin and therefore produce collagen in the skin. In theory it might work on cellulite. The problem is that thermage doesn't work on everybody. You won't be able to tell if it worked, or didn't work, until you have the procedure. For me the biggest barrier, besides the fact that it may not work on you, is also the fact that it's very expensive.
If you're going to do thermage, please know that it's not really meant for cellulite treatments. It may not work on you, even if you book the best doctor in the world. It is very costly.
Good luck and I hope that helps you decide if thermage works, or doesn't work, for cellulite.
