What is the difference between XERF and Thermage FLX?

Both treatments use radiofrequency (RF) energy to help improve skin elasticity, but they differ in how they are applied and in their characteristics. Thermage FLX delivers RF energy deep into the skin layers, helping to improve overall facial elasticity, lift the face, and reduce fine lines. XERF lets the doctor adjust energy delivery precisely to your skin condition, helping to improve skin texture and elasticity. The right treatment for you depends on your skin thickness, degree of sagging, and goals, so we recommend a customized treatment plan after a consultation with our medical staff.

XERFTreatment overview

XERF is a non-invasive lifting treatment that uses dual monopolar radiofrequency (RF) technology. It delivers RF energy precisely to the dermis and the subcutaneous fat layer, where loss of skin elasticity begins, to stimulate collagen regeneration and tighten skin tissue.
XERF uses two RF frequencies, 6.78 MHz and 2.0 MHz, so energy delivery can be adjusted for each skin layer. Built-in cryogen cooling protects the skin surface during treatment.
Settings such as 3-level depth adjustment and 10-level intensity adjustment let an experienced practitioner treat precisely, so wide areas from the face to the neck and jawline can be lifted effectively.
XERF suits people who want natural, visible lifting without incisions. It also suits people who value a short treatment time and fast recovery.
