XERF Structural Skin Tightening
Tighten, Lift, and Firm Without Needles
Sagging skin, a softening jawline, and fine lines don’t always call for surgery or injectables. XERF brings a clinically studied, non-invasive alternative to CLEO Clinic, using the world’s first dual-frequency monopolar RF technology to reach the shallow, middle, and deep layers of the skin in one session — with zero downtime.
What Is XERF?
XERF is a non-surgical skin-tightening device that uses dual-frequency monopolar radiofrequency (RF) energy — combining 6.78 MHz and 2 MHz in a single treatment — to heat multiple tissue depths at once and stimulate collagen remodelling, without needles, numbing, or downtime.
Developed by Cynosure Lutronic, XERF is marketed as “Structural Skin Tightening” because, unlike conventional single-frequency RF devices that treat one depth at a time, it’s engineered to reach the dermis, superficial tissue, and deeper structural layers linked to sagging — all in one pass, without switching handpieces.
Unlike treatments that rely on a fixed energy setting, XERF uses Accurate Impedance Feedback to read each patient’s skin in real time and adapt its energy delivery accordingly — meaning the treatment adjusts to your unique skin profile rather than applying a one-size-fits-all approach.
How Does XERF Work?
XERF’s dual-frequency energy penetrates to a targeted depth beneath the skin, generating controlled heat that thickens and strengthens collagen and elastin fibres, while a built-in cooling system protects the skin’s surface throughout — which is part of why numbing cream typically isn’t required.
This is what makes XERF a genuine multi-depth treatment:
- Surface Firming (6.78 MHz) — Higher-frequency energy concentrates in the more superficial dermal layers, improving skin firmness, texture, and fine lines.
- Mid-Face Tightening (2 MHz) — Lower-frequency energy reaches deeper into superficial tissue, tightening looser skin across the cheeks and mid-face.
- Structural Lifting (Deep Setting) — The deepest setting targets the structural layer associated with jawline definition, jowls, and under-chin laxity.
Dual-Frequency Radiofrequency (RF) Technology
XERF is the world’s first multifrequency monopolar RF treatment, combining a higher frequency (6.78 MHz) that concentrates energy in more superficial layers with a lower frequency (2 MHz) that reaches deeper tissue. Used together or individually, this lets your doctor address surface-level fine lines and deeper jawline or neck laxity in the same session, without switching devices.
Accurate Impedance Feedback
Rather than applying a fixed setting to everyone, XERF reads the skin’s electrical impedance in real time during treatment. This lets the device adapt energy delivery to each patient’s unique skin profile — thicker, thinner, more or less hydrated tissue all conduct energy differently, and this feedback loop is part of what keeps the treatment personalised throughout a session.
Treatment Depth Settings
XERF offers three depth settings and ten intensity levels:
- Shallow (dermis): targets fine lines, skin texture, and surface firmness
- Middle (superficial tissue): addresses looser mid-face and cheek skin
- Deep (structural layer): reaches the tissue associated with jawline definition and under-chin laxity
Built-in cooling technology is applied alongside energy delivery to protect the skin’s surface throughout — part of why XERF typically doesn’t require numbing cream.
Three adjustable depth settings and ten intensity levels let your doctor tailor a single session to address several concerns — from surface texture to deeper sagging — without needing separate devices or additional visits.
Areas XERF Can Treat
XERF's applicator is designed for precise use across the face and neck, making it a versatile option for a range of concerns:
- Jawline and jowl definition
- Double chin and under-chin laxity
- Cheeks and mid-face firmness
- Neck laxity and crepey skin
- Fine lines and early collagen loss
- Brow area support

XERF pricing isn’t a flat rate — it depends on a few factors your doctor will confirm at consultation:
- Area treated — face, face and neck, or targeted zones like the jawline or under-chin are priced differently
- Depth and intensity settings used — a session addressing all three depth levels typically takes longer than a single-depth treatment
- Number of sessions recommended — most patients see the best results from a short course rather than a single visit
- Doctor and clinic experience — pricing reflects the practitioner’s training and the clinic’s equipment standards

What to Expect: Your XERF Treatment Journey
Session duration: A typical session takes well under an hour, depending on the areas treated and depth settings used.
Recommended course: Most patients see the best results from a short course of sessions rather than a single visit, similar to other RF-based tightening treatments — your doctor will confirm the right number for your skin during consultation.
Downtime: None — you can return to normal activities, makeup, and skincare immediately after treatment.
Results timeline: Some tightening may be noticeable early on, but XERF works primarily by stimulating your body’s own collagen remodelling, so firmness and lift continue to develop gradually over the following weeks to months.
XERF Procedure
Before the Treatment
No numbing cream or special preparation is typically required. During your consultation, your doctor will assess your skin laxity, facial structure, and concerns to decide whether XERF alone or a combination approach — for example, alongside a collagen biostimulator — better suits your goals.
During the Treatment
The handpiece is passed across the treatment area while dual-frequency energy is delivered along with continuous surface cooling. Most patients describe the sensation as warmth rather than pain, and a session across the face and neck typically takes well under an hour depending on the areas treated.
Zero Downtime and Recovery
There’s no recovery period — you can return to normal activities, makeup, and skincare immediately. Mild, temporary redness or warmth in the treated area is common and usually settles within a few hours. Results build gradually as new collagen forms, becoming more visible over the following weeks to months.
Is XERF Right for You?
XERF is best suited for those who:
- Have mild-to-moderate skin laxity across the face, jawline, or neck
- Want to improve skin firmness and texture without surgery or fillers
- Are looking for a needle-free, numbing-free treatment
- Want zero downtime and the ability to return to normal activities immediately
- Are exploring preventive, maintenance-level skin tightening before laxity becomes more pronounced
XERF isn’t designed to replace surgery for significant sagging or to restore lost facial volume — a consultation with our doctors at CLEO Clinic will confirm whether XERF alone is the right fit, or whether combining it with another one of our signature treatments would give you the best results.

5 Key Benefits of
XERF Structural Skin Tightening
5 Problems XERF Solves
Softening Jawline & Jowls
Reaches the structural layer linked to jawline definition and jowl sagging.
Mild Double Chin & Under-Chin Laxity
Firms loose submental tissue without needles or surgery.
Loss of Mid-Face Firmness
Tightens looser cheek and mid-face skin at a superficial-tissue depth.
Neck Laxity & Crepey Skin
Supports firmer, smoother-looking neck skin over a course of sessions.
Fine Lines & Early Collagen Loss
Higher-frequency energy improves surface texture and fine lines at the dermal level.
Clinical Evidence and Results
XERF is built on decades of research into monopolar radiofrequency for skin tightening, rather than being an entirely new mechanism. In-vivo histological studies on the XERF system have shown collagen bundle thickening at multiple tissue depths following treatment, alongside internal tissue temperatures adequate to trigger collagen remodelling, according to data published by the manufacturer, Cynosure Lutronic.
Independent reviews of monopolar radiofrequency more broadly support a real, if gradual, improvement in mild-to-moderate skin laxity — consistent with a 2011 review in the Journal of the American Academy of Dermatology and a 2024 systematic review in the journal Cosmetics, both of which found the technology to be a reasonable option for this category of concern. As with any energy-based device, individual results vary, and outcomes should be judged against realistic expectations rather than marketing claims of an instant or surgery-level lift.
Side Effects and Risks
XERF is generally considered low-risk. The most common effects are temporary warmth, mild redness, or slight swelling in the treated area, which typically resolve within a few hours to a day. Because XERF doesn’t target melanin, the risk of pigment-related side effects — a concern with some laser treatments on Asian skin — is comparatively low.
As with any energy-based device, incorrect settings or inexperienced handling can increase the risk of complications, which is why treatment at CLEO Clinic is always performed or supervised by an LCP-certified doctor.

Frequently Asked Questions
XERF Structural Skin Tightening
XERF stands for eXperience Exponential RF, a dual-frequency monopolar radiofrequency device developed by Cynosure Lutronic.
XERF is generally described as a comfortable treatment. Its built-in cooling system keeps the skin's surface comfortable throughout the session, while dual-frequency RF energy works beneath the surface — most patients describe the sensation as warmth rather than pain.
Most patients see the best results from a short course of sessions rather than a single visit, though your doctor will tailor the exact number to your skin laxity and goals during consultation.
Because collagen remodelling is a gradual biological process, firmness and tightening typically develop progressively over the weeks following each session, with continued improvement as you complete your treatment course.
No. XERF uses dual-frequency radiofrequency energy to heat multiple tissue depths at once, while HIFU uses focused ultrasound to create concentrated thermal points at specific depths. Both aim to stimulate collagen for tightening, but through different energy types — see our HIFU facelift page for more detail.
XERF uses monopolar radiofrequency technology built on decades of clinical research into RF skin tightening, and doesn't target melanin — keeping pigment-related risk comparatively low. As with any aesthetic treatment, suitability should be confirmed with a qualified doctor during consultation.
XERF is completely non-invasive — no incisions, no anesthesia, and no downtime — making it suitable for those who want firmer, tighter-looking skin without surgery. A surgical facelift remains the more direct option for significant sagging or excess skin, but requires a recovery period that XERF doesn't.
