What is XERF?

Made in Korea. Goes deeper than Thermage® — without the pain.

XERF is made in Korea by Lutronic and is the world’s first multifrequency monopolar radiofrequency treatment. By combining two frequencies (6.78 MHz and 2 MHz), it delivers heat deeper than conventional RF — down to the SMAS, the foundational layer that lifts and supports the face — to tighten skin and rebuild collagen. Built-in cooling keeps the surface comfortable, so no numbing cream is needed.

  • Deeper reach Three depth settings target shallow, middle and deep layers, including the SMAS.
  • Comfortable Advanced cryogen cooling protects the skin’s surface. No numbing, no needles.
  • Personalized Real-time skin impedance feedback and ten intensity levels tailor every pass to you.
  • No downtime Return to your day right away. Firmness builds as new collagen forms.

Who is it for?

Ideal candidates and treatment areas

XERF is well-suited to a broad range of patients, particularly those experiencing mild to moderate skin laxity who wish to address visible signs of aging without surgery or prolonged recovery.

You may be a good candidate if you notice:

  • Softening of the jawline or early jowling
  • Loose or crepey skin along the neck
  • Loss of definition in the cheeks or midface
  • Fine lines and skin laxity around the eyes and brows
  • Skin laxity on the arms, abdomen, or thighs

Areas we treat

  • Jawline and jowls: lifting and defining the lower face
  • Neck: smoothing laxity for a more youthful profile
  • Cheeks and midface: restoring firmness and contour
  • Brows and periorbital area: softening laxity and fine lines around the eyes
  • Nasolabial folds and marionette lines: improving facial harmony
  • Arms: addressing crepey or loose skin along the posterior upper arms
  • Abdomen: tightening lax skin following weight changes or natural aging
  • Thighs: improving skin quality and firmness
