The better version of Thermismooth is the Thermitight procedure. Both Thermismooth and Thermitight both use radiofrequency energy to heat up the skin to cause skin tightening. The Thermitight procedure gives patients much better results due to more effective heating delivered from inside out. The areas are first numbed with numbing fluid. A gentle probe is inserted under the skin to heat up the skin for maximum contraction. The Thermitight procedure is painless after numbing.
