Loose skin along the jawline, cheeks, and neck is often one of the first changes that prompts people to look for a way to firm up without surgery. Radiofrequency has long been the go-to answer, and for years, Thermage was the name everyone knew. Now something more advanced has arrived: XERF, the world’s first multi-frequency monopolar RF device.
As one of the first practices in New York to introduce XERF alongside established options like Thermage, SKINNEY Medspa gets asked the same question almost daily: XERF vs Thermage, which is better? Both tighten skin with radiofrequency energy, and neither requires surgery, but they get there differently. Which skin tightening treatment works best? Here is a clear look at how XERF compares to Thermage, so you can understand the real difference between XERF and Thermage and decide which one fits your skin.
Key Takeaways:
- XERF and Thermage are both forms of radiofrequency skin tightening that stimulate collagen to firm and lift skin without surgery.
- XERF is the newer technology, using two RF frequencies to target the shallow, middle, and deep layers, while Thermage uses a single frequency with a long, proven track record.
- XERF treatments tend to be more customizable and more comfortable, thanks to adjustable depth and intensity settings plus integrated cooling.
- Thermage is typically a single session with touch-ups every 1 to 2 years, while XERF is usually performed as a short series with ongoing maintenance.
- The best RF treatment for skin tightening depends on your skin, your goals, and an in-person assessment with a qualified provider.
What Is RF Skin Tightening?
Radiofrequency skin tightening uses controlled heat to warm the deeper layers of skin, where collagen and elastin are found. When those fibers reach a certain temperature, the skin contracts slightly right away, and over the following weeks, the body produces fresh collagen for firmer, smoother skin with no incisions and little to no downtime.
Because it works beneath the surface rather than removing skin, RF skin tightening is a popular non-surgical option for anyone who wants to soften early sagging without committing to a facelift. As a collagen-stimulation treatment, it gradually and naturally improves laxity and works best on the lower face, jawline, neck, brows, and eyes, where laxity first appears. Both XERF and Thermage fall into this category of skin-tightening treatments, and what separates them is how deeply each can work and how comfortable the experience is.
XERF Treatment: The New Standard in Structural Skin Tightening
XERF is a non-invasive radiofrequency device that represents a real leap forward in RF technology. It is FDA-cleared and the world’s first multifrequency monopolar RF treatment, which is at the heart of what makes the XERF treatment different from everything before it.
How XERF Works
Rather than relying on a single frequency, XERF combines 6.78 MHz and 2 MHz. The higher frequency treats the more superficial layers, while the lower frequency reaches much deeper, down to the SMAS, the same structural layer surgeons address during certain facelifts.
By working across the shallow, middle, and deep layers, XERF delivers what its makers call structural skin tightening, which can mean more meaningful lift than surface-level RF on its own.
The system also reads your skin as it works, using real-time impedance feedback to fine-tune energy delivery to your tissue from moment to moment. Paired with its pulse technology, that feedback helps keep heat where it belongs and the surface protected throughout the session.
Why XERF Stands Out
A few features set XERF apart as a facial skin tightening option:
- Customization: 3 depth settings and 10 intensity levels, plus real-time skin analysis, so the treatment adapts to your skin rather than the other way around.
- Comfort: integrated cooling and a Never-Numb design mean no numbing cream and no needles, with most clients feeling only gentle warmth.
- Efficiency: sessions often run around 45 minutes with no downtime, with only a possible mild pinkness that usually fades within hours.
Because it works across multiple depths, XERF can treat both the face and body, from the jawline, cheeks, and neck to the abdomen, arms, and thighs. Many people notice subtle tightening soon after a session, with continued firming as collagen rebuilds over the following months. That makes it a strong choice for anyone exploring skin tightening without surgery. Among collagen stimulation treatments for aging skin, XERF stands out for the kind of gradual, natural-looking improvement SKINNEY clients tend to want.
Thermage Treatment: The Established RF Option
Thermage is the treatment that made radiofrequency skin tightening mainstream. It is an FDA-cleared monopolar RF device with a long clinical history and millions of treatments performed worldwide, so it is well understood and widely trusted.
The Thermage treatment uses a single 6.78 MHz frequency, paired with a comfort pulse and surface cooling. It heats the deep dermis evenly, which is part of why its results tend to be consistent and predictable across the treated area. The heat works in two stages: it immediately contracts existing collagen for a subtle initial tightening, then prompts the body to build fresh collagen over the months that follow.
It is also best known as a one-and-done option. Most people have a single session; results develop over 3 to 6 months as collagen remodels, and the improvement often lasts 1 to 2 years. For someone who wants a proven, established Thermage treatment for loose skin and prefers a single visit with only occasional touch-ups, it remains a solid choice.
XERF vs Thermage for Skin Tightening
Both treatments tighten skin with radiofrequency, and neither requires surgery, but the differences matter when you are choosing. Here is the difference between XERF and Thermage at a glance.
Depth and Energy
This is the biggest distinction. Thermage delivers one frequency, while XERF delivers two and reaches deeper structural layers, including the SMAS. For deeper laxity, the dual-frequency design is why many providers view XERF as the more advanced skin laxity treatment.
Comfort and Customization
Older RF treatments could feel hot. XERF’s integrated cooling and adjustable settings make sessions both more comfortable and more tailored, while Thermage relies on its comfort-pulse system. When it comes to customization, XERF’s depth and intensity options simply give the provider more control.
Sessions
Thermage is usually a single session, with touch-ups every 1 to 2 years. XERF is typically a short series of treatments, followed by periodic maintenance to maintain results. Your provider maps out the right number of XERF sessions at your consultation, based on your skin and goals.
Results
With XERF, many people notice an immediate tightening effect right after a session, with the most significant results developing around 3 months later as new collagen builds. Both deliver gradual, natural-looking results and can show meaningful change in RF skin tightening in before-and-after photos when performed by an experienced provider.
Which Treatment Is Right for You?
Choosing the best treatment for face and neck skin tightening comes down to your skin, your goals, and how your provider reads your laxity in person.
XERF may be the better fit if you:
- Want the newest technology and deeper, structural tightening
- Are addressing early or mild to moderate laxity along the jawline, cheeks, and neck
- Prefer a customizable, comfortable, needle-free session
That makes it a particularly appealing XERF treatment for skin laxity in those early-to-moderate stages, when staying ahead of sagging matters most.
Thermage may suit you if you:
- Prefer a single, established annual treatment with a long track record
- Want even, predictable tightening across larger areas
- Are focused on softening deeper lines as much as lifting
For many people looking for a non-surgical treatment for sagging skin, XERF’s structural approach and comfort make it the most exciting place to start, which is why SKINNEY highlights it for clients weighing their options. The only way to know for sure is through a professional assessment, since the right wrinkle-reduction treatment and tightening plan is always personalized to you.
It is also worth knowing that RF is not your only path. SKINNEY offers a full range of tightening technologies, including ultrasound-based Sofwave, and the right plan sometimes pairs treatments to address both laxity and texture. During your consultation, your provider can map out whether XERF alone, Thermage, or a combination makes the most sense for your skin and goals.
