WonderTouch vs. XERF: What’s the Difference?
WonderTouch and XERF are two of the newest names in non-surgical skin tightening, and both use monopolar radiofrequency. They are not the same treatment, though. They use different frequencies, feel very different on the skin, and follow different treatment plans. Here is how they compare.
The Short Answer
XERF is a high-energy, single-session style treatment. It pairs two radio frequencies with built-in cooling to heat deep layers of skin in short, intense pulses. WonderTouch is a gentler, massage-based treatment. It uses a lower frequency, delivered through electrodes and the provider’s hands, as a comfortable series with no downtime.
Quick guide: Consider XERF if you want one intensive session and don’t mind stronger heat. Consider WonderTouch if you want a relaxing, needle-free treatment you can repeat, combine with other services, and use on both face and body.
First, What Is Monopolar RF?
Radiofrequency (RF) treatments warm the deeper layers of your skin. That controlled heat tells your body to remodel and build new collagen, which is what makes skin look firmer and lifted over time.
“Monopolar” describes how the energy travels. A treatment electrode on the skin sends the current through the tissue to a return pad elsewhere on the body. Because the energy has to travel through the body to reach that pad, monopolar RF can reach deeper than the bipolar and multipolar devices common in spas. Thermage, the original monopolar RF brand, has used this approach for more than two decades. XERF and WonderTouch are newer takes on the same idea.
How XERF Works
XERF is made by Cynosure Lutronic. Its signature feature is dual frequency: it combines 6.78 MHz energy, the same frequency Thermage uses, with a second, lower 2 MHz frequency that is designed to travel deeper.
- Three depth settings let the provider focus on shallow, middle or deep layers.
- Built-in cooling protects the surface of the skin while the heat goes deeper.
- A disposable treatment tip is used for each session. That cost is part of why XERF is usually priced as a premium, one-time treatment.
- One session is the norm, with tightening developing gradually over the following months.
You will feel quick pulses of strong heat, softened by the cooling. Downtime is usually minimal.
How WonderTouch Works
WonderTouch, from XOD, uses 448 kHz monopolar radiofrequency, a much lower frequency that was first developed in Europe for therapeutic treatments. Instead of short, intense pulses, the provider delivers the energy continuously through electrodes and guided massage techniques. It has three modes:
- Capacitive targets water-rich surface layers for tightening, texture and circulation.
- Resistive targets denser, deeper tissue for contour and the look of cellulite.
- Systemic is a hands-free, full-body mode that supports circulation and lymphatic flow.
Clients describe it as a warm, relaxing massage. There are no needles, no consumable tips and no downtime, and many people leave with a visible glow. It is done as a series, and because it is so gentle, it pairs easily with facials, peels, injectables and weight loss programs. See our WonderTouch treatment page ›

Why We Love WonderTouch
Both treatments use monopolar radiofrequency to warm the deeper layers of skin and support new collagen. What makes WonderTouch stand out is what it’s like to actually get it — and what it costs.
It’s genuinely relaxing. WonderTouch is done by hand. Your provider glides warm electrodes over your face and neck with slow massage movements, so it feels like a warm facial massage. Many clients say they nearly fall asleep. XERF, by comparison, delivers quick, strong bursts of heat that the cooling tip has to soften.
There’s no pain. No needles, no numbing cream and no recovery. You walk out with a glow and go straight back to your day — makeup can go right back on.
It’s more affordable. XERF uses a single-use treatment tip each time and is sold as a premium one-time treatment, so the upfront cost is high. WonderTouch has no disposable tips, so each session costs less. At Valley Aesthetic a session is $500, and your first Face + Neck visit is just $149, with a skin analysis included.
Most people do about 6 sessions, twice a week, and see firmer, smoother-looking skin build over 4 to 12 weeks.

Monopolar RF is needle-free and focuses on tightening. RF microneedling, like the Secret™ RF treatment we offer, is different: fine needles deliver the energy directly into the skin. That makes microneedling the better choice for acne scars, enlarged pores and rough texture, with a few days of redness afterward. Many clients combine the two, using microneedling for texture and WonderTouch for ongoing firmness. Learn about Secret RF microneedling ›
Which Should You Choose?
XERF may suit you if: you prefer a single, more intensive treatment, and are comfortable with stronger heat.
WonderTouch may suit you if: you want a comfortable, needle-free treatment with no downtime, want to treat your body as well as your face, are pairing tightening with weight loss or other services, or simply enjoy a treatment that feels like self-care.
The best way to decide is a consultation. Your skin, your goals and your schedule all matter.
WonderTouch & XERF FAQs
What is the difference between WonderTouch and XERF?
Both are needle-free monopolar radiofrequency skin tightening treatments. XERF, made by Cynosure Lutronic, uses higher-frequency energy (6.78 MHz plus 2 MHz) with built-in cooling and a disposable treatment tip, and is usually done as one intensive session. WonderTouch, from XOD, uses a lower 448 kHz frequency delivered through electrodes and massage, with no consumable tip and no downtime, and is done as a series.
Which one hurts less?
WonderTouch is generally the more comfortable experience. Most people describe it as a warm massage. XERF delivers more intense heat in short pulses, and uses cooling to protect the skin surface, so you will feel stronger bursts of heat.
Is there downtime with either treatment?
Neither treatment usually requires downtime. Some people have temporary redness after either one.
How many sessions do I need?
XERF is typically performed as a single session, with results developing over the following months. WonderTouch is usually done as a series, and many clients notice a lifted, glowing look after the first visit.
Does Valley Aesthetic offer WonderTouch?
Yes. Valley Aesthetic in North Bergen, NJ offers WonderTouch monopolar RF, along with Secret RF microneedling for texture and acne scars. New clients can try a first WonderTouch Face + Neck session for $149, skin analysis included.
