Most skin tightening treatments are based on bipolar radiofrequency energy that cannot penetrate the skin as deeply as TempSure Envi, which is a monopolar radiofrequency treatment the penetrates heat deep into the dermis. Older monopolar radiofrequency treatments are much more painful and expensive than TempSure Envi. TempSure Envi also allows your practitioner to monitor the skin temperature continuously and in real time, meaning that your skin will be heated to perfect temperature quickly and efficiently, with no lost treatment effect or complications due to too high or too low skin heating.
