XERF is a non-invasive radiofrequency (RF) skin-tightening treatment designed to heat deeper layers of tissue and stimulate collagen remodeling.
How it works
RF energy penetrates below the skin — XERF uses 6.78 MHz and 2 MHz RF frequencies to deliver energy at different tissue depths.
Tissue heats up — controlled heating causes existing collagen fibers to contract and triggers a wound-healing/remodeling response.
Collagen remodeling begins — over the following weeks and months, fibroblasts produce and reorganize collagen and other extracellular-matrix components.
Skin gradually becomes firmer — this can translate into improved laxity, smoother texture, and more defined facial contours.

What’s the difference between XERF and Thermage FLX ?
Both XERF and Thermage FLX are non-invasive monopolar radiofrequency (RF) treatments used primarily for skin tightening and collagen remodeling. The biggest difference is how the RF energy is delivered and controlled.
The important technical difference
Thermage:
6.78 MHz RF → volumetric heating → collagen contraction/remodeling
XERF:
6.78 MHz + 2 MHz RF → ability to change how energy is distributed through tissue → broader/deeper heating strategies
The lower 2 MHz frequency isn't simply “twice as deep.” Actual heating depth depends on tissue impedance, electrode geometry, power, pulse duration, contact, and treatment technique. That's important when explaining XERF scientifically.
For patients, I would simplify it to:
Thermage = 经典单极射频紧肤
以紧致、胶原重塑为主，技术成熟，但治疗时部分客人会觉得热感比较明显。
XERF = 新一代双频单极射频
通过 6.78MHz + 2MHz 双频射频，可以更灵活地进行不同层次的组织加热，在紧致、轮廓塑形和胶原刺激的同时，更强调治疗舒适度。
For your med-spa menu, I wouldn't market XERF as simply “a cheaper Thermage.” They overlap heavily, so positioning them around different patient needs is more useful: Thermage = established premium RF tightening; XERF = dual-frequency RF with customizable energy delivery and comfort emphasis.
