XERF™ Skin Tightening Treatment in London
Structural Skin Tightening Without Needles or Downtime
Harley Street Injectables is one of the early London clinics to introduce XERF™, an advanced multifrequency radiofrequency treatment designed to improve skin laxity, firmness and facial definition without needles or surgery.
Using both 6.78 MHz and 2 MHz monopolar radiofrequency, XERF delivers controlled energy at different tissue depths to stimulate collagen remodelling and support the skin’s underlying structure.
The result is a personalised, non-invasive approach to skin tightening, with no routine numbing and no planned downtime.
What Can XERF Improve?
XERF is designed to address visible signs of ageing associated with loss of skin firmness and structural support.
It may help to improve:
Loose or lax skin
Loss of facial firmness
A softening jawline
Lower-face laxity
Neck laxity
Fine lines and wrinkles
Overall skin smoothness and firmness
Early signs of facial ageing
Clinical research is also investigating XERF for facial ageing, eyebrow lifting and laxity affecting the lower face, submental area and neck.
Your practitioner will assess your skin during consultation and advise whether XERF is appropriate for the area you would like to treat.
How Does XERF Work?
XERF uses controlled monopolar radiofrequency energy to heat targeted tissue beneath the skin.
This controlled heating affects collagen-rich structures at different depths and encourages collagen contraction and longer-term remodelling, helping the skin gradually feel firmer and appear tighter.
What makes XERF different is its use of two radiofrequency frequencies:
6.78 MHz
Targets relatively more superficial and intermediate tissue levels.
2 MHz
Allows energy to reach deeper supporting tissue.
The system combines these frequencies to work across shallow, middle and deep treatment depths, rather than taking a one-depth-fits-all approach.
TREATMENT TIME
Varies depending on the area treated
PAIN LEVEL

Why is XERF Different?
Real-Time Skin Feedback
XERF uses Accurate Impedance Feedback to analyse how the skin is responding to energy during treatment, helping your practitioner tailor energy delivery in real time.
Designed for Comfort
Wave Fit™ pulse technology controls the way energy is delivered, while Integrated Cryogen Delivery (ICD) cools the surface of the skin with each pulse.
This allows XERF treatments to be performed without routine topical numbing.
No Needles
XERF delivers RF energy through the surface of the skin, with no injections or microneedles involved.
Suitable for Different Skin Types
According to Cynosure Lutronic, XERF can be used across all skin types, with treatment settings personalised to the individual patient.

XERF vs Other Skin-Tightening Treatments
XERF vs traditional monopolar RF
XERF combines two radiofrequency frequencies, 6.78 MHz and 2 MHz, allowing energy to be delivered across different treatment depths.
XERF vs RF microneedling
RF microneedling uses small needles to deliver radiofrequency energy into the skin. XERF is completely non-invasive and delivers RF energy through the skin surface without needles.
XERF vs HIFU
HIFU treatments use focused ultrasound energy to target tissue beneath the skin. XERF uses radiofrequency energy and offers adjustable depth and intensity settings.
What Happens During a XERF Treatment?
Your treatment begins with a consultation and assessment of your skin, facial structure and areas of concern.
Your practitioner will then select the appropriate XERF depth and energy settings for your treatment.
As the device delivers radiofrequency energy, you may feel periods of controlled warmth. XERF's integrated cooling system works alongside each pulse to help protect the skin surface and make treatment more comfortable.
Topical anaesthetic is not routinely required.
The exact treatment time will depend on the areas being treated and your personalised treatment plan.
PREPARATION AND AFTERCARE
XERF™ requires minimal preparation and has no planned downtime.
Before Treatment
Arrive with clean skin where possible.
Tell your practitioner about any recent treatments, medication changes or skin concerns.
No numbing cream is usually required.
After Treatment
Mild redness, warmth or swelling may occur temporarily.
Keep skincare gentle and wear SPF daily.
Avoid excessive heat for 24 hours.
Follow any personalised aftercare advice from your practitioner.
FAQs
-
Some patients may notice an initial feeling or appearance of increased firmness soon after treatment.
Further improvement can develop gradually as collagen remodelling takes place over the following weeks and months. Cynosure Lutronic reports both immediate and progressive tightening following treatment.
A recently published small retrospective study also found improvements in facial laxity and several measures of skin quality following a single XERF treatment, although the authors emphasised that the findings are preliminary and require confirmation in larger controlled studies.
Results vary between individuals and depend on factors including your age, skin condition, degree of laxity and treatment plan.
Your practitioner will advise whether a single treatment or a course of treatments is most suitable for you.
-
XERF is designed as a non-invasive treatment with no planned downtime, so most patients can return to their usual activities after treatment.
Temporary effects can occur following radiofrequency treatment. In a recent clinical study of XERF, reported effects included short-lived redness and mild swelling, resolving within one to two days in the affected patients.
Your practitioner will explain possible side effects and aftercare before your treatment.
-
No. Although XERF is sometimes described online as a skin-tightening “laser”, it actually uses radiofrequency energy.
XERF combines 6.78 MHz and 2 MHz monopolar RF energy to heat tissue at different depths and support collagen remodelling.
-
XERF is designed with patient comfort in mind. You can expect to feel warmth as radiofrequency energy is delivered.
Wave Fit™ technology controls the energy pulse while Integrated Cryogen Delivery cools the skin surface. Routine numbing cream is therefore generally not required.
Individual sensitivity varies, and your practitioner can adjust the treatment settings according to your response.
-
There is no fixed treatment plan suitable for everyone.
Some patients may be treated with a single session, while others may benefit from additional treatments depending on their age, skin laxity and desired outcome.
Your practitioner will recommend a personalised treatment plan following consultation.
-
XERF is a non-surgical skin-tightening treatment and cannot reproduce the degree of tissue repositioning achievable with surgery.
It is generally better suited to patients looking for a non-invasive improvement in skin firmness and laxity without surgical recovery.
Your practitioner can advise whether your expectations are realistic for a non-surgical treatment.
-
Cynosure Lutronic states that XERF is suitable for all skin types.
However, suitability still needs to be assessed individually. Your medical history, skin condition and previous treatments will be reviewed before treatment.
-
Potentially. XERF may form part of a wider treatment plan alongside other skin, injectable or energy-based treatments.
The order and timing of treatments matter, so your practitioner will advise how XERF can safely fit into your personalised treatment plan.
-
The longevity of results varies between individuals and depends on factors such as your age, skin condition, degree of laxity and natural ageing process.
XERF stimulates a collagen-remodelling response, so improvement develops gradually rather than stopping immediately after treatment.
Your practitioner can advise when maintenance treatment may be appropriate based on your individual response.
