XERF is a monopolar RF medical device that combines 6.78MHz and 2MHz
frequencies to selectively deliver thermal energy from superficial to deep skin layers,
inducing lifting and tightening effects.
With 3 depth levels and 10 energy levels,
customized treatment is possible based on individual skin type and treatment area.
XERF can treat the face, jawline, and neck in one session, with efficient energy delivery
selectively transferring heat from superficial to deep skin layers.
