If you’re noticing sagging skin, loss of firmness, or the early signs of aging but aren’t ready for surgery, XERF introduces a more advanced approach to skin tightening in New York City. As the world’s first multi-frequency monopolar RF treatment, XERF uses dual frequencies to deliver energy with greater precision, helping tighten, smooth, and lift skin exactly where it needs it most. With customizable depth and intensity settings, real-time skin analysis, and integrated cooling technology for a more comfortable Never-Numb™ experience, XERF offers a personalized treatment designed around your skin, not a one-size-fits-all approach.
XERF is the first skin tightening treatment of its kind. It is a non-invasive treatment that uses advanced multi-frequency radiofrequency (RF) technology to stimulate collagen production and firm the skin from the inside out.
Unlike regular treatments that only target the skin’s surface, XERF is the first system to use multiple frequencies of monopolar RF technology, helping reshape the skin at deeper levels for better, more visible results.
XERF works by delivering dual-frequency RF energy (6.78 MHz and 2 MHz) into the skin at different depths, allowing providers to treat both superficial and deeper structural layers.
Here’s what makes it different:
Key benefits include the following:
Many patients notice an initial tightening effect, with continued improvement over time as collagen rebuilds.
XERF is highly versatile and can be used on both the face and body. Common treatment areas include:
It is especially effective in areas where skin laxity is mild to moderate.
*results may vary
Patients are raving about XERF because it delivers a level of skin tightening and lifting that many traditional non-surgical treatments simply cannot match, without the downtime or intensity of surgery. Its multi-frequency RF technology allows for more precise energy delivery at multiple skin depths, helping create firmer, smoother, more lifted-looking skin while still offering a comfortable, personalized treatment experience.
XERF doesn’t just treat the surface. It targets deeper layers where aging actually begins, leading to more meaningful, longer-lasting results.
By using two RF frequencies, XERF can customize depth and intensity for more precise and effective outcomes.
One of the most exciting aspects of XERF is that many patients notice an immediate tightening effect, known as “the first peak,” shortly after treatment. While some of this early improvement may soften over the following days, the most significant results typically develop around three months later as new collagen production increases. This second phase brings firmer, smoother, and more noticeable long-term skin tightening.
You can return to normal activities immediately after treatment, making it ideal for busy NYC lifestyles.
With integrated cooling and advanced pulse delivery, treatments are designed to be comfortable without the need for numbing.
Instead of drastic changes, XERF enhances your natural features by rebuilding collagen over time.
When it comes to advanced skin tightening like XERF, your results depend just as much on the provider as the technology itself. SKINNEY Medspa designs every detail of your experience around expertise, customization, and real, visible outcomes.
Your treatment is performed by a team of registered nurses and laser-certified licensed estheticians who specialize in advanced aesthetic procedures. This level of clinical training ensures your XERF treatment is both safe and results-driven.
SKINNEY Medspa is known for offering a full range of radiofrequency and collagen-stimulating treatments, including Sofwave, Thermage, and other tightening technologies. This means your provider understands exactly how to customize XERF for your skin, rather than using a one-size-fits-all approach.
With locations in two of the most competitive aesthetics markets, SKINNEY Medspa has built a reputation for delivering consistent, high-quality results. The practice is known for attracting discerning clients and maintaining high standards of care.
Every treatment is designed to enhance your natural features, not overcorrect them. The goal with XERF is firmer, smoother, healthier-looking skin that still looks like you, just refreshed and more youthful.
XERF is a powerful skin tightening treatment, but your results ultimately depend on the expertise behind it. At SKINNEY Medspa, you are not just getting advanced technology. You are trusting a skilled team that knows how to tailor each treatment for real, visible results.

“XERF uses two radiofrequency frequencies in one treatment, which lets us gently heat different layers of skin at the same time. It's designed for a wide range of skin tones, and the built-in cooling keeps you comfortable while your skin starts building new collagen.”
“XERF is what I reach for when a client is bothered by loose skin on the stomach, arms or jawline, especially after weight loss. Most people need just one session, and you can start to see things tighten up over the following months.”
“If you've been told certain lasers aren't right for your skin tone, this is a great conversation to have with me. It feels warm, not painful, and I love seeing a client's jawline look sharper and more defined a few months later.”
XERF is the world’s first multi-frequency monopolar radiofrequency treatment, and that distinction matters more than it might sound. Most RF skin tightening devices operate on a single frequency, which means they can only target one depth of tissue at a time. XERF uses two frequencies simultaneously, 6.78 MHz and 2 MHz, allowing it to treat both superficial and deeper structural layers of skin in a single session. That is what makes it structural skin tightening rather than surface-level tightening. The result is more comprehensive collagen stimulation, more precise energy delivery, and more meaningful improvement than single-frequency devices can achieve. If you have tried other skin tightening treatments in NYC and felt like the results were underwhelming, XERF is worth a serious look.
XERF delivers dual-frequency radiofrequency energy into the skin using 2 frequencies, 6.78 MHz and 2 MHz, that work together to target both superficial and deeper structural layers simultaneously. As the energy heats these layers, it does two things at once. It contracts existing collagen immediately, which creates an initial tightening effect you may notice right after your session, and it stimulates new collagen and elastin production in the deeper structural layers for longer-lasting lift and firmness over time. The result is both an immediate improvement and a progressive one that continues to build over the following weeks and months. Real-time skin analysis built into the device allows your provider to customize depth and intensity as they go, so the treatment is always calibrated to your skin.
XERF is highly versatile and can be used on both the face and body. On the face, common treatment areas include the jawline and jowls, cheeks and midface, under the chin, forehead, and neck. On the body, XERF can address skin laxity on the abdomen, arms, and thighs. It is especially effective in areas where skin laxity is mild to moderate, making it a strong option for patients who are starting to notice changes but are not ready for surgery. If you have a specific area in mind that is not on this list, bring it up at your consultation and we will tell you honestly whether XERF is the right tool for it.
These treatments are all non-surgical skin tightening technologies, but they work differently and produce different results. Sofwave uses ultrasound energy to stimulate collagen in the mid-dermis, making it a strong option for fine lines and mild laxity. Thermage uses radiofrequency energy to tighten and smooth skin by stimulating collagen deep in the dermis. Ultherapy goes even deeper, using focused ultrasound to target the same structural layer addressed in a surgical facelift. XERF is the only device that uses two RF frequencies simultaneously to address multiple tissue depths in a single pass, giving providers more flexibility and patients more comprehensive results. At SKINNEY we offer all of these technologies across our NYC locations, which means our experts can recommend the right one, or the right combination, based on your skin and goals rather than defaulting to whatever is most available.
Because it solves a problem that every previous RF device had. Until XERF, monopolar radiofrequency treatments could only operate at a single frequency, which meant they could only target one depth of tissue per pass. Getting comprehensive results required either multiple devices or multiple treatment types, each with their own sessions, costs, and recovery considerations. XERF changes that by delivering two frequencies simultaneously, reaching both superficial and deeper structural layers in a single session. That is not an incremental improvement. It is a fundamentally different approach to how RF energy is delivered. Add in real-time skin analysis, integrated cooling, and a treatment experience comfortable enough to skip the numbing cream entirely, and you have a device that represents a meaningful leap forward rather than just a new name on familiar technology. That is why it is generating the kind of attention it is among both providers and patients in NYC and beyond.
Your session begins with a quick skin assessment and cleansing of the treatment area. The XERF handpiece is then moved across the skin in a series of passes, delivering dual-frequency RF energy to the targeted layers. Real-time skin analysis guides the treatment throughout, allowing depth and intensity to be adjusted as needed based on your skin’s response. Most patients describe the sensation as a warm, building heat that is comfortable throughout. Sessions typically take around 45 minutes, and there is no recovery period required afterward, making XERF one of the easiest treatments to fit into a busy NYC schedule. Your provider will walk you through what to expect before your first pass so there are no surprises.
Most patients find XERF very comfortable. The treatment delivers a building warmth as the RF energy penetrates the skin, and the integrated cooling technology manages surface temperature throughout so it never gets to the point of being painful. Most people describe it as feeling like a hot stone massage or deep, focused heat. There is no need for numbing cream, which is part of what makes XERF stand out as a comfortable treatment that still delivers real results. Sensitivity varies from person to person and by treatment area, and your provider will adjust the settings throughout your session to keep you comfortable without compromising effectiveness.
The right number of sessions depends on your skin, your specific concerns, and the level of improvement you are looking for. Many patients see meaningful results after a single session, with results continuing to build over the weeks and months that follow as new collagen develops. Some patients choose additional sessions to build on their initial results or address larger treatment areas. Your provider will recommend a personalized plan during your consultation based on your skin and goals. Either way, the collagen-building process continues long after you leave the treatment room, which means your results keep improving even between sessions.
No. One of XERF’s most appealing qualities for busy NYC patients is that there is zero required downtime. You can return to your normal activities, apply makeup, and go about your day immediately after your session. Some patients notice mild redness or warmth in the treated area that typically resolves within a few hours. Because XERF does not damage the skin’s surface, there is no peeling, flaking, or prolonged sensitivity to manage afterward. It is the kind of treatment you can genuinely do on a lunch break and walk back into your afternoon looking the same, just with collagen-building already underway beneath the surface.
Every XERF treatment at SKINNEY is performed by a team of registered nurses and laser-certified specialists who specialize in advanced energy-based treatments. This is not a treatment we hand off to whoever is available. The skill of the provider matters significantly with XERF because real-time skin analysis requires someone who knows how to read the skin’s response and adjust depth and intensity throughout the session. At SKINNEY, that clinical expertise is built into every appointment. Before your first session you will meet with your provider, walk through your skin concerns and goals, and understand exactly what the treatment will involve and what to expect when you leave. You are in experienced hands from the moment you walk in.
XERF produces results in 2 phases. The first phase is an immediate tightening effect, often called the first peak, that many patients notice right after their session or within the first few days. This happens because RF energy contracts existing collagen on contact. Some of this initial improvement may soften slightly over the following days, which is completely normal and not a sign that the treatment did not work. The second and more significant phase typically develops around the 3 month mark as new collagen production increases, bringing firmer, smoother, and more noticeable long-term skin tightening. Results continue to improve as collagen rebuilds, which is why patients often find their skin looks better 3 months out than it did right after their session.
Results from XERF develop gradually and continue to improve as your body produces new collagen in the weeks and months following treatment. Because XERF works by stimulating your own collagen production rather than adding a foreign substance, the results integrate naturally into your skin and hold up over time. Results typically last up to a year or longer depending on your skin, your age, and how well you protect and maintain your skin after treatment. Sun protection is especially important, since UV exposure is one of the primary drivers of collagen breakdown. Many patients schedule periodic sessions to preserve and build on their results. Your provider will recommend a maintenance timeline based on how your skin responds.
This is one of the most important things to understand about XERF before your first session. The immediate tightening you may notice right after treatment comes from the contraction of existing collagen fibers in response to heat. It is real and it is visible, but it is not the full story. The more meaningful and lasting improvement comes from the new collagen your body produces in the weeks and months that follow, a process that continues for up to 3 to 6 months after treatment. Think of the immediate result as a preview and the long-term result as the main event. Patients who understand this timeline tend to be the most satisfied with their outcomes because they know what to expect and when.
Yes. By stimulating collagen and improving skin elasticity, XERF helps soften fine lines and wrinkles over time. It is particularly effective for lines associated with skin laxity and loss of structural support, such as those around the jawline, neck, and lower face. It is not a replacement for injectables when it comes to deep expression lines or significant volume loss, but it significantly improves overall skin quality and firmness in a way that makes the whole face look more refreshed. Many SKINNEY clients in NYC combine XERF with Botox or dermal fillers for a more comprehensive result that addresses both structure and surface.
They are different tools for solving different problems. A surgical facelift physically lifts and repositions tissue, removes excess skin, and produces dramatic, long-lasting results that no non-surgical treatment can fully replicate. XERF is not a facelift, and we will never position it as one. What XERF can do is produce meaningful, natural-looking improvement in skin firmness and laxity for patients who are not ready for surgery, want to maintain results between surgical procedures, or simply prefer a non-invasive approach. For patients with mild to moderate laxity, XERF can deliver results that are genuinely impressive. For patients with more significant sagging, it can be part of the plan but may not be sufficient on its own.
XERF is a strong fit for adults who are noticing early to moderate signs of skin laxity and want meaningful improvement without surgery, needles, or downtime. Good candidates include patients who are starting to see softening along the jawline, looseness in the neck, loss of definition in the cheeks, or crepey texture on the face or body. It works well for patients who want to be proactive about aging before changes become more advanced. XERF is also a great option for patients who have experienced skin laxity following significant weight loss, including those who have completed a GLP-1 program. Your provider will assess your skin at your consultation and give you an honest read on whether XERF is the right fit.
Not everyone is a candidate for XERF, and we would rather tell you that upfront than waste your time and money. RF energy is not safe for patients with certain metal implants or electronic devices like pacemakers near the treatment area, and XERF is not recommended during pregnancy. Patients with active skin infections or inflammatory skin conditions in the treatment area should wait until those resolve. And if your skin laxity is beyond what XERF can meaningfully address, we will say so and discuss what would actually serve you better. Your provider reviews your full health history at your consultation so there are no surprises and no wasted sessions.
Yes. One of XERF’s significant advantages over many laser-based skin tightening treatments is that it is safe for all skin tones, including darker complexions. Because radiofrequency energy targets tissue based on heat rather than pigment, there is no risk of post-inflammatory hyperpigmentation or other pigment-related side effects that can affect darker skin tones with certain laser treatments. This makes XERF one of the most inclusive skin tightening options available and a particularly strong choice for patients who have been told they are not ideal candidates for laser-based alternatives. At SKINNEY, we treat a diverse clientele in NYC, and XERF works beautifully across the full spectrum of skin tones.
Yes, and combining treatments is often how our clients get the most complete results. XERF pairs well with Botox and dermal fillers, since XERF addresses structural laxity while injectables address dynamic lines and volume loss. Together they cover more ground than either approach alone. XERF also combines well with Emsculpt NEO for body treatments, where XERF addresses skin quality and laxity while Emsculpt NEO builds the underlying muscle. For patients coming off a GLP-1 weight loss program, XERF is one of our top recommendations for addressing the skin laxity that sometimes follows significant weight loss. One of our experts can build a combination plan during your consultation based on your specific goals and timeline.
The gap between professional XERF treatments and at-home RF devices is significant. At-home devices are intentionally limited in the energy they deliver for safety reasons, which means they cannot reach the tissue depths required for meaningful structural tightening. XERF delivers medical-grade RF energy at clinical intensity levels, with real-time skin analysis and integrated cooling that allows for precise, powerful treatment that no consumer device can replicate. The dual-frequency technology that makes XERF unique does not exist in the at-home market. If you have been using an at-home device and wondering why the results feel modest, this is why. Professional treatment is a different category entirely.
SKINNEY was among the first practices in NYC to offer XERF, which means our providers have more hands-on experience with this technology than most. Results from XERF depend heavily on the skill of the provider operating the device, including how they read the skin in real time, how they adjust depth and intensity across different treatment zones, and how they sequence XERF within a broader treatment plan. At SKINNEY, every XERF treatment is performed by a team of registered nurses and laser-certified specialists who specialize in advanced energy-based treatments. You are not getting a first session from someone still learning the device. You are getting a team that has refined their technique across a high volume of treatments right here in NYC.
At SKINNEY, we offer a full range of skin tightening technologies including Sofwave, Thermage, Ultherapy, and Morpheus8 alongside XERF. That breadth of options is actually what makes us different. Because we are not limited to one device, our providers can recommend the treatment that genuinely fits your skin rather than defaulting to whatever is most available or most profitable. Your consultation includes a thorough skin assessment, a conversation about your goals and timeline, and an honest recommendation about which technology or combination of technologies will get you where you want to go. Sometimes that is XERF. Sometimes it is something else. We will always tell you which one we think is right.
XERF is available at SKINNEY Medspa across our NYC locations including our Flatiron Flagship at 125 Fifth Avenue, our 30 East 60th Street location, and our Saks Fifth Avenue location at 611 Fifth Avenue. All 3 locations are easily accessible from across Manhattan and the surrounding boroughs, making it simple to find a spot that works for your schedule. SKINNEY was among the first practices in New York City to offer XERF, which means our team has accumulated more hands-on experience with this technology than most providers in the area. Wherever you are coming from in the city, there is a SKINNEY location close to you.
Early access and high volume. SKINNEY was an early adopter of XERF in New York City, which means our providers have accumulated significant hands-on experience with the technology in a short time. That experience translates directly into better outcomes for patients. Beyond XERF specifically, SKINNEY’s broader expertise in energy-based skin tightening, body contouring, and injectables means your provider is not thinking about XERF in isolation. They are thinking about how it fits into your full aesthetic picture and how to combine it with other treatments to get you the most complete result. That integrated approach is what separates a great outcome from a good one.
Booking is straightforward. You can call us directly at (646) 212-0554, book online through our website, or stop into any of our NYC locations to schedule your consultation in person. We have multiple locations across Manhattan including our Flatiron Flagship at 125 Fifth Avenue, our 30 East 60th Street location, and our Saks Fifth Avenue location at 611 Fifth Avenue. New clients can take advantage of our new client offer when booking for the first time. Our team will confirm your appointment, answer any questions you have ahead of time, and make sure you know exactly what to expect before you come in.
