XERF

XERF is an advanced, non-invasive radiofrequency skin tightening treatment designed to improve skin firmness, facial definition and overall skin quality. Using dual-frequency radiofrequency technology, XERF delivers controlled energy at different depths within the skin to stimulate collagen production and support gradual skin tightening.

The treatment can be used to address early to moderate skin laxity, softening around the jawline, reduced firmness and changes in skin texture. With no needles or surgery required, XERF provides a non-surgical option for patients looking to improve the appearance of loose or ageing skin with minimal interruption to their normal routine.

About

XERF

XERF is an advanced skin tightening treatment suitable for patients who are beginning to notice reduced firmness, early jowling, a softer jawline or loose and crepey skin around the face and neck. The treatment uses monopolar radiofrequency energy to heat targeted tissue beneath the surface of the skin, encouraging existing collagen fibres to contract while supporting the production of new collagen over time.

Unlike conventional radiofrequency systems that may work predominantly at one depth, XERF uses two frequencies, 6.78 MHz and 2 MHz, which allow energy to be delivered at different levels within the tissue. This enables the practitioner to tailor treatment according to the area being treated, the depth of the tissue and the degree of skin laxity.

During treatment, the XERF handpiece is passed across the skin while controlled radiofrequency energy is delivered beneath the surface. Different settings can be used to target shallower, middle and deeper tissue levels, allowing areas such as the forehead, cheeks, jawline and neck to be treated according to their individual structure and needs.

XERF also incorporates a cooling system designed to help protect the surface of the skin and improve patient comfort while thermal energy is delivered below. Most patients describe the treatment as a warming sensation, and anaesthetic or numbing cream is not normally required.

The treatment can be used on the face, jawline, under the chin, neck and décolletage, as well as selected areas of the body where skin laxity is a concern. It may be particularly suitable for patients looking to improve early jowls, a loss of jawline definition, loose neck skin or a general reduction in skin firmness.

Results develop gradually as the skin responds to the treatment and produces new collagen. Some patients may notice an initial improvement in firmness, with further changes becoming visible over the following weeks and months as collagen remodelling continues. The number of treatments required will depend on the degree of laxity, the area being treated and the individual patient’s goals.

Patients considering XERF at Ambra Clinic in Finchley will receive a consultation and skin assessment before treatment. This allows the practitioner to identify the areas contributing to loss of definition or firmness and select appropriate treatment settings rather than applying the same protocol across the whole face. XERF can also form part of a wider personalised treatment plan where skin quality, volume changes or other signs of ageing need to be addressed separately.

FAQ

Am I suitable for the XERF Facial Treatment?

XERF Facial may be suitable for adults experiencing early to moderate skin laxity, loss of facial definition or reduced firmness who would prefer a non-surgical treatment.

It can be particularly useful for concerns around the lower face, jawline, neck and under the chin. Your practitioner will assess your skin quality, medical history and treatment goals during consultation to determine whether XERF is appropriate for you.

Is the XERF Facial safe?

Yes. XERF Facial is a non-invasive radiofrequency treatment designed to deliver controlled energy into targeted tissue while cooling helps protect the surface of the skin.

Treatment should always be carried out by an appropriately trained practitioner. Your medical history and suitability will be assessed beforehand, and the settings can be adapted according to your skin and the area being treated.

Is treatment painful?

XERF is generally well tolerated. Most patients describe feeling warmth as the radiofrequency energy is delivered into the skin.

The system incorporates cooling to help maintain comfort at the skin surface, and numbing cream or anaesthetic is not normally required. Sensation can vary depending on the area being treated and the energy settings used.

Are there any side effects or risks?

Temporary redness, warmth, mild swelling or sensitivity can occur after treatment. These effects are generally short-lived and should gradually settle.

As with any energy-based treatment, there are potential risks, which your practitioner will discuss during your consultation. Following the recommended aftercare can help support the skin as it settles following treatment.

How much downtime should I expect?

There is generally little to no downtime following XERF treatment. Most patients can return to work and their usual daily activities shortly after their appointment.

The skin may appear slightly red or feel warm for a short period, but this usually settles without requiring a prolonged recovery period.

How many XERF treatments will I need?

The number of XERF treatments recommended will depend on your skin condition, the areas being treated and the level of improvement you would like to achieve. Some patients may benefit from a single treatment, while others may be advised to have a short course.

When will I see results from XERF?

Some patients may notice an early improvement in firmness following treatment, but results usually develop gradually as collagen production and remodelling continue. Further improvements may become visible over the following weeks and months.

How long do XERF results last?

Results will vary between patients and will be influenced by factors such as age, skin condition and lifestyle. As the natural ageing process continues, maintenance treatments may be recommended to help preserve improvements in firmness and definition.

What areas can be treated with XERF?

XERF can be used on areas of the face and body where skin laxity or reduced firmness is a concern. Common treatment areas include the cheeks, jawline, under the chin, neck and décolletage. Your practitioner can advise which areas are suitable during consultation.

How is XERF different from other radiofrequency treatments?

XERF uses two radiofrequency frequencies to deliver energy at different depths within the tissue. This allows treatment to be adapted according to the area being treated and the degree of skin laxity, while integrated cooling helps maintain comfort at the skin surface.
