As non-surgical aesthetic treatments continue to develop, many people are exploring ways to improve skin firmness without undergoing surgery. One treatment gaining attention is XERF, a non-invasive skin-tightening treatment that uses dual-frequency monopolar radiofrequency (RF) technology.
But what exactly is XERF, how does it work, and what should you know before considering it? Understanding the technology, its potential benefits and its limitations can help you decide whether it is worth discussing with an aesthetic doctor.
What Is XERF Treatment?
XERF is a non-invasive skin-tightening treatment that uses monopolar radiofrequency energy. It is designed to deliver controlled energy into different tissue depths to support skin tightening and improve the appearance of skin laxity.
Unlike treatments that use needles to deliver energy into the skin, XERF delivers radiofrequency energy externally through a treatment handpiece. It does not require the skin to be punctured as part of the energy-delivery process.
XERF is intended for people who want to explore non-surgical options for concerns such as reduced skin firmness and mild facial laxity. However, suitability depends on the person’s skin condition, facial structure and desired outcome.

How Does XERF Work?
XERF uses two monopolar radiofrequency frequencies: 6.78 MHz and 2 MHz. The system delivers these frequencies in sequence as part of its approach to heating different tissue depths.
Radiofrequency energy generates controlled heat within the targeted tissue. This heating can cause changes in existing collagen and initiate a tissue-remodelling response. Collagen is an important structural protein that helps support the skin’s firmness and elasticity.
As the skin responds to treatment, gradual changes in firmness may develop. The extent of any visible improvement varies between individuals and cannot be guaranteed.
What Makes XERF Different From Conventional Radiofrequency Treatments?
XERF combines two frequencies in one treatment pulse. The system also incorporates cooling technology and adjustable treatment settings that allow the practitioner to tailor energy delivery to the treatment area and the individual’s needs.
These technical features are designed to help control how energy is delivered. However, having different frequencies or adjustable settings does not automatically mean that one treatment will produce better results for every patient. Treatment outcomes depend on several factors, including the individual’s skin condition, the treatment protocol and the practitioner’s assessment.
What Skin Concerns May XERF Help Address?
XERF is designed for non-surgical skin tightening. Depending on the individual’s concerns and suitability, a practitioner may consider it when the main goal is to improve the appearance of skin firmness.
1. Mild Skin Laxity
Skin can gradually lose some of its firmness as the body ages. Changes in collagen, skin structure and underlying facial support may contribute to a less-firm appearance.
Radiofrequency-based treatments are designed to heat targeted tissue and support remodelling. XERF may be considered for selected patients with mild skin laxity, although the degree of improvement varies and deeper structural changes may require a different approach.
2. Less-Defined Facial Contours
Some people notice that the cheeks, lower face or jawline appear less defined over time. Skin laxity may contribute to this change, although fat distribution, facial structure and volume changes can also play a role.
Where reduced skin firmness is a contributing factor, a skin-tightening treatment may be considered as part of an individualised treatment plan. XERF should not, however, be presented as a guaranteed way to create a sharper jawline or remove fat beneath the chin.
3. Visible Signs of Facial Ageing
Changes in skin firmness and the appearance of fine lines can occur as facial skin ages. XERF has been studied for facial laxity and lower-face lifting, but the available clinical evidence is still developing.
It is important to distinguish between a treatment’s intended purpose and the results that have been firmly established through research. An assessment can help determine whether XERF is appropriate for the particular concern or whether another option should be considered.
What Are the Potential Benefits of XERF Treatment?
XERF has several features that may make it worth discussing with a qualified aesthetic practitioner if you are exploring non-surgical skin tightening.
- Non-invasive treatment: Radiofrequency energy is delivered through an external treatment handpiece rather than through needles.
- Dual-frequency technology: The system combines 6.78 MHz and 2 MHz radiofrequency energy as part of its approach to treating different tissue depths.
- Adjustable treatment settings: Energy delivery can be tailored by the practitioner according to the treatment area and individual assessment.
- Potential improvement in skin firmness: Radiofrequency treatments are intended to support tissue heating and remodelling, although the degree of visible improvement varies.
- No surgical incisions: XERF does not involve the incisions required for a surgical facelift.
These features describe how the treatment is designed to work. They should not be interpreted as a guarantee of a particular result, comfort level or recovery experience.
What Does the Clinical Evidence Say About XERF?
Clinical research specific to XERF is emerging, so it is important to interpret reported results carefully.
A prospective multicentre study published in 2026 followed 39 participants who received two sessions of dual-frequency non-invasive monopolar radiofrequency treatment. The researchers reported improvements in clinician-rated assessments at follow-up visits, including at 90 days.
However, the study was relatively small and did not include a control group. The authors’ findings support further investigation, but they do not establish exactly how much improvement every patient can expect, how long results will last, or whether XERF is superior to other skin-tightening treatments.

For patients, the practical takeaway is to approach XERF with realistic expectations. A treatment assessment should consider the available evidence alongside the individual’s skin condition, treatment goals and alternatives.
What Should You Expect During a XERF Session?
The process may vary according to the clinic’s protocol and the treatment area. In general, a non-invasive radiofrequency session involves an assessment, preparation of the treatment area and delivery of energy using the treatment handpiece.
Before Treatment
The practitioner should discuss your concerns, medical history, previous aesthetic procedures and treatment expectations. This is also an opportunity to discuss possible side effects, contraindications and whether a different treatment may be more appropriate.
During Treatment
The practitioner applies the treatment handpiece to the planned areas and adjusts the settings according to the treatment protocol. Sensations can vary between individuals and treatment areas. Ask the practitioner what to expect and let them know if you experience significant discomfort.
After Treatment
Recovery varies. Some people may experience temporary redness, tenderness or other local reactions after radiofrequency treatment. Your practitioner should explain the expected recovery period, provide appropriate aftercare instructions and advise you when to seek medical review.
Do not assume that every patient will have no downtime or that side effects are impossible simply because the treatment is non-invasive.
Are There Any Risks or Limitations?
Non-invasive treatments can still have side effects and may not be suitable for everyone. The possible risks depend on the device, treatment settings, treatment area and the person receiving the treatment.
Potential issues to discuss with your practitioner include temporary redness or tenderness, discomfort during treatment, burns and changes in skin pigmentation. The practitioner should explain which reactions are expected and which symptoms require prompt review.
XERF also has important treatment limitations:
- Results vary and cannot be guaranteed.
- It is not a substitute for a surgical facelift when substantial lifting is required.
- Skin tightening does not necessarily address concerns mainly caused by excess fat, significant volume loss or underlying facial structure.
- The published XERF-specific clinical evidence remains limited, and further research is needed to clarify long-term outcomes.
Before proceeding, disclose your relevant medical history and any previous procedures. Follow the practitioner’s advice about suitability, precautions and aftercare.
Who May Be Suitable for XERF?
XERF may be worth discussing with an aesthetic doctor if you are looking for a non-surgical approach to improving skin firmness and understand that the outcome may be modest.
However, the most appropriate treatment depends on what is causing the concern. A person whose main concern is mild skin laxity may need a different plan from someone with significant excess skin, substantial volume loss or fat beneath the chin.
A qualified practitioner can assess your skin, explain the realistic treatment goals and help you compare suitable options. The consultation should include both the potential benefits and the limitations of XERF.
