RF energy delivered to exactly the right depth — firming, lifting, and redefining your skin's structure from within.
6.78 & 2 MHz
What Is XERF?
XERF is the world's first multifrequency monopolar radiofrequency system — a new class of skin tightening that delivers thermal energy to precisely controlled depths within the skin.
Where traditional RF treatments apply energy at a single frequency, XERF combines 6.78 MHz and 2 MHz simultaneously — targeting superficial and deep structural layers in one session. An onboard Accurate Impedance Feedback (AIF) system reads your skin in real time, adapting energy delivery pulse by pulse.
