What Is XERF? XERF vs. RF Microneedling | Plano, TX
Dr. Sophia Rahman of Plano, TX, explains what XERF is, how needle-free XERF differs from RF microneedling, and what the FDA cleared it for.
Patients have started asking me about XERF by name, or by the name Cynosure gives it, structural skin tightening. That usually means they’ve seen it online before they’ve had a chance to ask a physician about it. I’m adding XERF to my practice in Plano, TX, and before anyone books, I want to explain plainly what it is, what it is actually cleared to do, and how we’ll decide together whether it makes sense for your skin.
What Is XERF?
XERF is a monopolar radiofrequency (RF) device from Cynosure Lutronic, the same company behind the LaseMD Ultra laser I already use. Its FDA clearance is held by Lutronic Corporation.
In its FDA filing, XERF is described as an electrosurgical unit that uses high-frequency electrical current. The energy is delivered non-invasively, through the tip of a handpiece placed on the skin. The treated tissue is heated, and that heating results in coagulation. A return pad placed on your back disperses the energy and completes the circuit.
What the FDA clearance actually says
I think you deserve to see the cleared wording itself rather than a marketing summary. XERF was cleared through the FDA’s 510(k) process in August 2025, and its indication reads:
“XERF is indicated for use in dermatologic and general surgical procedures for electrocoagulation and hemostasis.”
Cynosure’s name for the treatment is “Structural Skin Tightening,” and the company states that it uses the term “skin tightening” to describe tightening effects that occur via soft tissue coagulation. That is the sense in which I use the phrase too, and it’s why I stay close to that language here.
XERF vs. RF Microneedling
This is the question I expect most, because many patients have heard of RF microneedling. The difference is in how the energy reaches your skin.
- RF microneedling uses fine needles to carry radiofrequency energy into the skin.
- XERF is needle-free. The energy is delivered through a handpiece tip resting on the skin’s surface, and nothing goes into the skin.
Cynosure describes a few features that shape how XERF delivers that energy:
- Two radiofrequency frequencies used together, which the company calls multifrequency monopolar RF
- Integrated cooling that cools the skin with each pulse
- Impedance feedback that reads the skin in real time so the treatment can be adjusted to each patient
Because the two approaches work so differently, I don’t think of XERF as a replacement for microneedling, or of either one as simply a better version of the other. They are different tools. Which one fits you, if either, depends on what we’re trying to address.
Who Might Be a Good Candidate
I’m not going to hand you a checklist here, and that’s deliberate. Whether XERF is right for you is something we decide together at a consultation, after I’ve:
- Looked at your skin in person and heard what’s actually bothering you
- Reviewed your health history and the medications you take
- Talked through what XERF is cleared for, and what a realistic expectation looks like for you specifically
Sometimes the answer will be XERF. Sometimes it will be a different treatment, or nothing at all. A device being new and popular is not, on its own, a reason to use it on your face.
What “K-Luxe” Means
You may also come across the name K-Luxe. K-Luxe is not a separate device, and it has no FDA clearance of its own. It’s Cynosure’s name for pairing a XERF treatment with the LaseMD Ultra laser, which I already offer here. Each device keeps its own cleared indication.
If pairing the two makes sense for your skin, we’ll discuss it at your consultation. You can read more about LaseMD Ultra at my practice.

Why a Physician-Led Practice
Energy-based devices are only as good as the judgment behind them. Cynosure’s own materials say that qualified healthcare professionals are responsible for diagnosis and treatment protocols, and that’s a responsibility I take seriously. Here is how I’m approaching XERF at my practice:
- Training first — I’m completing Cynosure’s certification training before I treat a single patient
- A real assessment — your skin, your health history, and your goals, reviewed by a board-certified Internal Medicine physician
- I perform every XERF treatment myself — the same physician who assessed you is the one treating you
- Careful patient selection — I’ll recommend XERF only when I think it genuinely fits, and I’ll tell you honestly when it doesn’t
- Clear education — what the device is cleared for, what we’re aiming for, and no promises I can’t stand behind
I’d rather you leave a consultation well informed and unconvinced than treated and disappointed.
Common questions
Is XERF a skin tightening treatment?
Cynosure calls XERF “Structural Skin Tightening.” The company states that it uses the term “skin tightening” to describe tightening effects that occur via soft tissue coagulation, and that is the sense in which I use it. Whether it fits your skin is something we decide together at a consultation.
Is XERF the same as microneedling?
No. RF microneedling uses fine needles to carry radiofrequency energy into the skin. XERF is needle-free: the energy is delivered through a handpiece tip resting on the skin’s surface.
What is XERF FDA-cleared for?
XERF was cleared through the FDA’s 510(k) process in August 2025. Its indication reads: “XERF is indicated for use in dermatologic and general surgical procedures for electrocoagulation and hemostasis.”
Is K-Luxe a separate device?
No. K-Luxe is Cynosure’s name for pairing a XERF treatment with the LaseMD Ultra laser. It has no FDA clearance of its own, and each device keeps its own cleared indication.
When can I book, and how?

Who decides if it’s right for me?
We decide together at a consultation, after I’ve looked at your skin in person and reviewed your health history and medications. Sometimes the answer will be XERF, sometimes a different treatment, or nothing at all.
If you’ve been curious about XERF, the best next step is a conversation, not a guess from an ad. See how XERF works at my practice and my other aesthetic treatments in the meantime, and when you’re ready: Call (972) 782-2811 to reserve — appointments begin the week of 16 November.
