The U.S. Food and Drug Administration (FDA) has cleared Cynosure Lutronic’s XERF system, a radiofrequency (RF) technology for skin tightening. This device combines 6.78 MHz and 2 MHz frequencies, enabling providers to precisely deliver energy at multiple tissue depths, effectively heating the fibrous septa to generate both immediate and lasting skin-tightening results. The device also features Wave Fit Pulse and Advanced Integrated Cryogen Delivery (ICD) Cooling Technology to regulate energy delivery and maintain optimal surface temperature for a comfortable treatment without the need for numbing. The device has a Spider pattern tip to reduce skin-edge effects.
