Noninvasive radiofrequency (RF) tissue heating is frequently used for skin tightening and facial wrinkle reduction as alternative to invasive surgical procedures. However, to ensure a safe and efficient therapy, the temperature of the skin and the subcutaneous tissue must be controlled in order to prevent tissue damage. We used numerical modeling to investigate the dynamics of the temperature increase in different tissue layers and found that targeted adipose tissue heating could be achieved for a wide frequency range of the applied RF signal. Using our model we can develop an optimal heating protocol to ensure safe and efficient RF therapy and to further improve RF devices.
