What is XERF?

XERF is a recently introduced monopolar RF lifting device. By combining two radiofrequency frequencies in one treatment, it aims to warm tissue at more than one depth for tightening and contour improvement.

How it works

Using two frequencies lets the device heat the dermis and the tissue beneath it in the same session. The heat causes collagen to contract and renew, giving an immediate tightening feel and gradual firming over the following weeks. A broad tip covers large areas quickly, and cooling protects the surface throughout. It belongs to the same family as Thermage FLX and Oligio.
