We Tried XERF — And Here's What We Think

I didn't come into this skeptical. But I didn't come in a believer either.

I'm the kind of person who reads the clinical data before the Instagram caption. So when XERF started flooding my feed — celebrities glowing, dermatologists explaining frequencies, before-and-afters that looked genuinely real — I did what any curious aesthetics-adjacent person does: I booked an appointment. At Total Body Aesthetic in Westchester, Los Angeles.

What followed was one of the most interesting 90 minutes I've spent in a treatment chair. And now I'm going to tell you everything — the device, the science, what it felt like, what I noticed afterward, and whether the hype matches the results.

What Exactly Is XERF?

XERF — short for eXperience Exponential RF — is a monopolar radio-frequency device manufactured by Cynosure Lutronic, the same company behind the Genesis and PicoSure Pro brightening lasers. It debuted in South Korea in 2024 and received FDA clearance for use in the United States in August 2025. In the months since, it has moved fast — from dermatology offices in New York to medical spas in Los Angeles, with a social media presence that's hard to miss.

What sets XERF apart from the crowded field of RF devices is its use of dual frequencies delivered simultaneously. Most tightening devices operate on a single frequency, which means they can only target one layer of the skin at a time. XERF uses two: 6.78 MHz, which works superficially to firm the skin's surface and smooth fine lines, and 2 MHz, which penetrates deeper into the subcutaneous layer to stimulate collagen remodeling and trigger a lifting effect. One treatment, two mechanisms, multiple depths.

The "monopolar" part of the equation refers to how the energy travels through the body. A flat treatment tip applies RF energy to the face, and that energy exits through a grounding pad — essentially a large adhesive bandage — placed on the lower back. It sounds like something out of a science fiction film. In practice, you don't feel the energy traveling at all. But knowing you're essentially plugged in while a handpiece glides across your cheekbones? That's a sensation that takes a moment to get used to.

A cooling system in the tip keeps the surface of the skin comfortable while the deeper energy does its work, which is a key reason why XERF does not require numbing cream — a significant quality-of-life advantage over some competing devices.

Who Is XERF For?

One of XERF's most impressive characteristics is its inclusivity. Because the device tip stays cool and the energy is controlled precisely, it is considered safe for all skin types and tones — including patients with melasma, who are often excluded from heat-based treatments due to the risk of hyperpigmentation. Clinical studies by Cynosure Lutronic confirmed efficacy across a wide range of complexions.

At TBA, our providers have found XERF particularly well-suited for patients who:

• Are in their mid-30s to late 50s and noticing early-to-moderate skin laxity
• Want visible lifting and tightening without surgery, needles, or significant downtime
• Have a softer, more rounded jawline or early jowling they'd like to address
• Are dealing with fine lines around the mouth, nasolabial folds, or under-eye crepiness
• Are on GLP-1 medications and want to address skin laxity that can accompany weight loss
• Want a comfortable treatment experience — the warm-massage sensation is manageable for almost everyone

Who Is XERF Not For?

As with any energy-based treatment, there are people who won't get the most from XERF — or for whom the treatment may not be appropriate at all.

• Significant skin laxity: If skin is visibly draping or deeply folded, XERF alone is unlikely to produce meaningful structural change. These patients may benefit more from surgical consultation or a combination of treatments.
• Very little facial tissue: Patients with a bonier, more angular facial structure may be at higher risk of overheating during treatment, as there is less soft tissue to absorb and distribute the energy. Your provider will assess this during your consultation.
• Implanted electronic devices: Anyone with a pacemaker, cochlear implant, or other implanted electronic medical device should avoid all energy-emitting treatments, including XERF.
• Unrealistic expectations: XERF is not a facelift. It will not deliver surgical results. What it will do — when properly performed on the right candidate — is meaningfully tighten, lift, and refine.

What Does the Treatment Actually Feel Like?

I arrived at TBA without numbing cream — because XERF doesn't require it. That fact alone set a different tone for the appointment. No 45-minute wait with a face full of lidocaine. I was brought into the treatment room, a grounding pad was placed on my lower back (the "plugged in" moment), and my provider applied a generous layer of conductor gel — essentially ultrasound jelly — across my face and neck.

Then the handpiece went to work.

The best description I can offer: a warm stone massage, with occasional pulses of heat that build and then fade. My provider started on the lowest intensity setting and moved in deliberate sweeping passes across the lower face, cheeks, and forehead. Every time the intensity was increased — which happened several times — I was asked first. On the moments it felt warmest, I'd rank the sensation at about a three or four out of ten. It passed quickly.

A full facial treatment consists of approximately 600 pulses — typically 250 to 275 on each side of the face, and around 100 for the forehead. If the neck is included, the session runs to roughly 900 pulses. From start to finish, expect between 45 minutes and an hour for the face alone. My session ran closer to 90 minutes because we worked the neck as well.

When it was over, my skin had the warm, slightly flushed look of someone who'd just come in from a brisk walk — pink, not red. The immediate tightness was noticeable and, honestly, exciting. A sheet mask was applied to calm the skin, and I was out the door within 20 minutes of the treatment ending.

What Is Aftercare Like?

XERF's aftercare is mercifully simple. For the first 24 to 48 hours:

• Avoid excessive heat sources — hot showers, saunas, steam rooms
• Skip active ingredients like retinoids, AHAs, and BHAs for 2 to 3 days
• Apply a gentle moisturizer and a barrier balm to keep the skin calm
• Wear sunscreen — more diligently than usual

By the time I reached my car in the parking lot at 8610 S Sepulveda, the warmth in my skin had already largely subsided. The next morning, my skin looked like my skin — just a more rested, slightly tighter version of it. No peeling. No raw patches. No canceling plans.

How Often Should You Get XERF?

The standard protocol recommended by Cynosure is two sessions, at least one month apart. However, at TBA, our providers typically prefer to space sessions further — three to six months apart — to allow collagen to fully rebuild before the next round of stimulation. Over-treating doesn't accelerate results; it just shortens the window of collagen production between sessions.

What the timeline looks like in practice:

• Immediately after treatment: Immediate tightening effect (temporary, due to collagen fiber contraction from heat)
• Weeks 2–8: Gradual firming as new collagen is produced
• After first treatment: Results typically last 3 to 4 months
• After second treatment: Results extend to 8 to 10 months

Younger patients tend to see longer-lasting results, as their baseline collagen production is higher. For best long-term outcomes, XERF is ideally viewed as part of an ongoing skin maintenance plan, not a single-event fix.

How Does XERF Compare to Other RF Treatments?

The landscape of non-surgical skin tightening is genuinely crowded. Here's how XERF stacks up against the devices patients ask us about most often:

Device	Technology	Numbing	Downtime	Depths Targeted
XERF	Monopolar RF, dual frequency	Not required	Minimal (hours)	Superficial + deep
Thermage	Monopolar RF, single frequency	Not required	Minimal	Single depth
Morpheus8	RF + microneedling	Required	3–5 days	Adjustable, needled
Sylfirm X	RF + microneedling (pulsed/continuous)	Required	2–4 days	Adjustable, needled
Ultherapy	Focused ultrasound (HIFU)	Recommended	Minimal–moderate	SMAS + skin layers

XERF's closest competitor is Thermage — both are monopolar RF, both require no numbing, and both have minimal downtime. The key difference is XERF's dual-frequency delivery, which allows it to address surface tightening and deep collagen remodeling at the same time. Thermage uses a single frequency and works at one depth per pass.

Ultherapy reaches deeper — down to the SMAS layer — and can be highly effective for significant lifting, but the discomfort level is considerably higher for many patients. At TBA, we sometimes pair XERF and Ultherapy for patients with greater laxity who want a comprehensive approach: Ultherapy targeting the jawline and outer face, XERF addressing the under-eye area and lines around the mouth that are harder to treat with Ultherapy's larger tip.

Morpheus8 and Sylfirm X combine RF energy with microneedling, delivering more aggressive remodeling at customizable depths. They require numbing and a few days of downtime, but they can address skin texture, pores, and scarring in ways that surface-only RF cannot. Many of our patients use Morpheus8 or Sylfirm X for their remodeling sessions and XERF for lower-downtime maintenance in between.

Can You Combine XERF With Other Treatments?

Absolutely — and this is where the real power of XERF shows up in a comprehensive treatment plan. At TBA, we frequently pair XERF with:

• Neurotoxins (Botox, Dysport): XERF tightens the skin's structure; neurotoxins address the dynamic wrinkles driven by muscle movement. Together, they cover different aging mechanisms for a more complete result.
• Sculptra or Radiesse: Biostimulatory fillers restore lost volume and collagen production deep in the tissue. XERF then works the skin's surface and mid-layer. The combination is particularly powerful for patients who've lost facial fullness.
• Emface: Emface lifts by stimulating the facial muscles; XERF tightens the overlying skin. When used together, they address both the muscular and dermal components of facial aging — a genuinely comprehensive approach.
• Lumenis IPL / ResurfX laser: Laser treatments improve skin tone, texture, and pigmentation. XERF improves firmness and lift. Combining the two addresses aging from multiple angles.

How Much Does XERF Cost?

A full two-session XERF series typically runs between $1,800 and $2,500 depending on the provider, location, and the scope of treatment (face only vs. face and neck). Single sessions can range from $900 to $1,400. Like most non-surgical skin tightening treatments, XERF is an investment — but for patients who want meaningful results without the cost, risk, and recovery of surgery, it often represents significant value.

At Total Body Aesthetic in Westchester, we offer complimentary consultations so you can understand exactly what you're getting, what to expect, and how XERF fits into your broader skin health goals before you commit to anything.

My Honest Take After One Treatment

I'll tell you what I noticed: within a day of my session, my face looked more defined. The jawline I'd been watching soften over the past two years looked sharper. The slightly heavy quality I'd noticed in my mid-face — that subtle downward drift that no amount of good skincare can fully address — felt subtly corrected.

The immediate tightening is real and it's exciting. But the more interesting thing is what happens in the weeks that follow, as the collagen stimulus gradually converts to actual structural change. That's where XERF earns its reputation — not in the dramatic before-and-after of the day of, but in the slow, accumulating firmness that builds over the next two months.

Was I converted? Yes — with a clear-eyed understanding of what it is and what it isn't. XERF is not a face lift. It is not going to reverse decades of aging in one session. But for patients in the right window — those noticing early-to-moderate laxity who want a comfortable, zero-downtime way to bank collagen and visibly lift the skin — it delivers in a way that's hard to dismiss.

I'm already scheduled for my second session.
