XERF is an advanced radiofrequency (RF) skin tightening treatment designed to lift, firm and refine the skin from within. Using dual-frequency monopolar RF, it delivers controlled heat across multiple depths of the skin to support collagen remodelling and improve firmness over time.
XERF was developed by Cynosure Lutronic and is often described as a Korean skin tightening treatment. The system combines two radiofrequency frequencies, 6.78 MHz and 2 MHz, to deliver controlled heating at different depths in a single pass.
At Omniya Clinic in Knightsbridge, XERF is tailored to your skin, anatomy and goals. Treatment aims to improve firmness around the face, jawline and neck without surgery. Little to no downtime is usually expected, although temporary redness, swelling or tenderness can occur.

Firmness is one of the first things to change. The jawline softens, the area under the chin loses definition, the neck begins to crepe, and the lower face can start to look a little heavier than it used to.
None of it happens overnight, which is exactly why it can be hard to treat. You may not want surgery, and you may not want to look different. You want to look like yourself, only more supported.
XERF is designed for this kind of gradual change. It uses dual-frequency monopolar radiofrequency, combining 6.78 MHz and 2 MHz energy, to deliver controlled heat beneath the skin surface. This energy can be directed across different depths, so each area can be treated according to its structure and level of laxity.
Shallow settings can be used for more delicate areas, middle depths for the mid-face and neck, and deeper settings for looser tissue around the lower face, jowls and under the chin. As the skin’s support layers are warmed in a controlled way, XERF helps stimulate the collagen response that supports firmer, tighter and smoother-looking skin over time.
Integrated cooling and controlled pulse delivery help protect the surface of the skin and keep treatment comfortable. The result is gradual, natural-looking firming: skin that feels more supported, with improved definition, while still moving and expressing naturally.
XERF is a non-invasive radiofrequency skin tightening treatment for the face and neck. It uses controlled heating beneath the skin’s surface to support collagen remodelling, without needles or incisions.
Although it is sometimes referred to as a “XERF laser”, XERF is not a laser. It does not use light energy or resurface the skin. Instead, it uses controlled radiofrequency heating beneath the skin surface to stimulate collagen contraction and longer-term collagen remodelling.
XERF is non-ablative, meaning it does not intentionally remove the skin’s surface. Integrated cooling helps protect the surface and manage comfort during treatment. Numbing cream is not usually required.
XERF is suited to early-to-moderate skin laxity and declining skin quality on the face, neck and selected body areas.
It is commonly used for:
If your concern is significant loose skin or advanced sagging, XERF may still form part of a wider plan, but we will tell you honestly if another treatment or surgery would serve you better.

XERF offers three treatment depths, allowing your practitioner to adapt treatment to different areas of the face and neck. Shallow and middle modes use 6.78 MHz radiofrequency; deep mode combines 6.78 MHz and 2 MHz to deliver heating into deeper tissue.
Preclinical studies in animal tissue have shown changes in collagen at several depths, including deeper supporting layers. These findings help explain how the technology works, but do not establish the degree of improvement an individual patient will experience.
XERF is not a substitute for surgery and does not produce surgical facelift results. For suitable patients, the aim is to use controlled radiofrequency heating to support collagen contraction and gradual remodelling over time.
Results vary from patient to patient, which is why treatment starts with a consultation. One of our skin specialists will assess your skin, explain what XERF can realistically achieve for you, and build a treatment plan around your anatomy, skin quality and goals.
Shallow energy can be used for more delicate areas, middle depths for the mid-face and neck, and deeper settings for looser tissue around the lower face, jowls and under the chin.
XERF uses integrated cooling and controlled pulse delivery to help protect the skin surface while the radiofrequency energy works beneath it. Most patients describe the sensation as deep warmth rather than pain.
XERF uses real-time skin feedback and adjustable settings, so your treatment can be adapted to your anatomy, skin quality and level of laxity.

varies per patient
XERF treatment cost depends on the area treated, your degree of laxity and whether your practitioner recommends a single session or a course.
At Omniya, pricing is confirmed after consultation because XERF is tailored to each patient. Treating the lower face and jawline may require a different plan from treating the full face and neck.
Your consultation includes:
Image shows before and 1 month after 1 treatment.
XERF is not designed to change your face overnight. The aim is subtle, natural-looking improvement that develops as your skin rebuilds its own collagen.
Skin may feel tighter, smoother and more supported
Firmness may begin to improve as collagen remodelling becomes more active
More visible improvement in jawline definition, lower-face firmness and neck texture
Continued improvement in elasticity, firmness and overall skin quality
Results vary depending on age, skin condition, lifestyle, degree of laxity and collagen response. Many patients choose maintenance treatments to preserve their results over time.

XERF is based on monopolar radiofrequency, a technology used in aesthetic medicine to create controlled heating within the skin and support collagen remodelling.
A 2024 preclinical study published in the Journal of Cosmetic Dermatology evaluated non-invasive monopolar radiofrequency using the XERF system in a porcine model. The study recorded controlled dermal heating at 50°C, 60°C and 70°C, while skin surface temperatures remained within measured safety limits under the study conditions. Histological analysis showed increased collagen density 30 days after treatment.
This supports the biological rationale for controlled radiofrequency heating and collagen remodelling. Individual results vary, and suitability should always be assessed in consultation.

XERF may not be suitable if you have significant skin laxity that would be better treated surgically, active infection or inflammation in the treatment area, certain implanted medical devices, or if you are pregnant or breastfeeding.
It may also be less appropriate if your main concern is acne scarring, enlarged pores, deeper texture change or lost volume. Treatments such as Morpheus8, laser resurfacing, injectables or a combined plan may serve you better in those cases.
Your consultation is designed to confirm whether XERF is likely to achieve the improvement you want. If another treatment or a surgical opinion would suit you better, our team will advise you.
Your XERF consultation at Omniya in Knightsbridge includes an assessment of your skin laxity, treatment areas and goals. We explain the improvement treatment may achieve, whether further sessions could be appropriate, and the recommended cost before you proceed.
Treatment prices include post-treatment reviews, typically at three and six months, to assess your response and discuss any next steps.

XERF is designed to improve skin firmness and support by using controlled radiofrequency heating to stimulate collagen remodelling. Suitable patients may notice firmer, smoother and tighter-looking skin over the weeks following treatment.
XERF treatment cost depends on the areas treated and the plan recommended. At Omniya, pricing starts from £2,000 and is confirmed after consultation.
How long results last varies with your skin condition, treatment plan and individual response. Improvement after one session does not necessarily have the same duration as improvement after a course.
Cynosure Lutronic’s typically recommends two treatments approximately six weeks apart, with results typically lasting around six months. Your practitioner will discuss realistic expectations and any maintenance treatment appropriate for you.
XERF and Ultherapy use different technologies. Ultherapy uses focused ultrasound, while XERF uses radiofrequency across multiple depths. The right choice depends on your skin, laxity and goals.
XERF is needle-free and non-ablative, while Morpheus8 uses RF microneedling. XERF may be better for comfortable, low-downtime tightening, while Morpheus8 may be preferred for texture, pores, scarring or more intensive remodelling.
Most patients describe XERF as warm and manageable rather than painful. No numbing cream is usually required.
Downtime is minimal. You may notice mild redness, warmth or tightness after treatment, but most patients return to normal activities straight away.
XERF is not a fat-reduction treatment. It uses controlled radiofrequency heating to target water-rich dermal and connective tissue rather than to destroy fat cells, and is designed to keep tissue heating within a therapeutic range for tightening and collagen remodelling, below the sustained temperatures associated with fat-cell destruction. The aim is to firm and support the skin while preserving your natural facial volume.
Because radiofrequency does not target pigment in the same way as some lasers, XERF may be suitable for a wide range of skin tones. Your practitioner will assess your skin before treatment and adjust settings accordingly.
You may see improvement after a single XERF treatment. Whether further treatment is appropriate depends on your skin laxity, goals and response.
Cynosure Lutronic recommends two treatments, usually 4–6 weeks apart, for optimal results. Your practitioner will explain whether that approach is appropriate for you and confirm the recommended plan and cost at consultation.
No. XERF is often searched for as a “XERF laser”, but it is not a laser. It uses radiofrequency energy rather than light energy to create controlled heating beneath the skin surface and support collagen remodelling.
XERF is best suited to patients noticing early jowls, reduced jawline definition, mild neck laxity, loose skin under the chin or a general loss of firmness, who want a non-surgical treatment with minimal downtime.
XERF may be worth considering if you want subtle, natural-looking tightening without needles, numbing or surgery. It is less suitable if you want a dramatic lift, or have more advanced laxity that would be better assessed surgically.
XERF was developed by Cynosure Lutronic and is widely associated with Korean skin tightening technology. It uses dual-frequency monopolar radiofrequency energy to treat multiple tissue depths.
Temporary redness, warmth, tenderness or swelling can occur after XERF. Possible complications include burns, blistering, changes in pigmentation or sensation, surface irregularities and scarring. Your practitioner will discuss the risks relevant to you, assess your suitability and explain what to do if you have concerns after treatment.
XERF is a non-invasive radiofrequency treatment with integrated cooling and controlled energy delivery. Suitability is assessed at consultation, particularly if you have implanted medical devices, active skin conditions or a complex medical history.
Before XERF, avoid strong exfoliating acids, retinoids and other active skincare on the treatment area unless your practitioner advises otherwise. Please also let us know if your skin is irritated, sunburnt or inflamed on the day, as treatment may need to be postponed.
Most patients return to normal activities the same day. Avoid excessive heat, saunas, steam rooms, intense exercise and strong active skincare for the period your practitioner advises, and use a daily SPF to protect your results.
If a second treatment is recommended as part of your initial plan, sessions are usually spaced 4–6 weeks apart. Maintenance treatments are considered separately, according to your results, skin condition and goals. Your practitioner will advise on suitable timing.
The Full Face & Neck treatment includes 900 shots.
The treatment covers the face and neck, including the crow’s feet area. Please note that (at the time of writing) the dedicated XERF eye tip has not yet been launched in the UK, so specific eye treatment is unavailable.
Yes, the initial consultation is included in this price. If booked separately prior to your procedure, it requires a £50 deposit, which is fully redeemable against your treatment.
Yes, your treatment price includes complimentary post-treatment reviews, which typically take place at 3 months and 6 months follow-up points to monitor your results.
