**4. The thermal evidence for soft tissue contraction using RFAL**

RFAL has been available internationally for 12 years and most recently, in 2016, has been approved for the intended use of soft tissue coagulation, by the FDA in the United States. There is a large body of literature that validates the use of internal thermal stimulation for soft tissue contraction, over and above what non-thermal techniques can deliver, as well as the increased efficiency and efficacy of using radiofrequency energy.
