What XERF is, and what it does, in 90 seconds
One treatment · No needles · No numbing · Back to work today
Firmer skin, a cleaner jawline and a tighter neck. The first change is visible the same day, then keeps building over the months that follow.
Before
After
Two of our patients on what XERF was actually like, and what changed afterwards.
Filmed at our London clinic. Individual results vary.
Two frequencies, three depths, and cooling built into the tip. This is what separates it from single-frequency radiofrequency.
Two minutes inside the skin: where each frequency lands, how the depths are chosen, and why it stays comfortable throughout.
At Dermamina, XERF is planned around your facial structure, skin firmness and treatment priorities. Your practitioner assesses where support is actually needed, then designs a focused plan rather than running the same programme across every face.
It suits patients who want firmer skin, a cleaner-looking jawline and natural collagen support without looking overdone.
Book nowIf you have already had skin tightening in London, this is the part worth reading. The technologies are not interchangeable and they do not behave the same way.

We assess your facial structure, skin firmness and lifting goals, then design a plan that specifies which areas are treated and at which depths. This is what makes dual-frequency worth having.
The handpiece is moved across the treatment areas, delivering controlled radiofrequency energy at the selected depths. Built-in cooling keeps the experience comfortable throughout. No numbing or needles are required.
There is no surgical downtime and you can return to normal activity immediately. Some tightening is visible early, with collagen-driven firming continuing to build over the following months.
XERF suits patients wanting firmer, tighter skin and a cleaner jawline without needles, injectables or surgery.
Every treatment is carried out in our Save Face accredited clinic on New Cavendish Street, five minutes from Oxford Street, by a medically qualified team.
An advanced non-invasive radiofrequency skin tightening treatment. It uses dual-frequency monopolar RF energy to warm selected tissue layers, stimulating collagen and producing a firmer, more lifted appearance.
Yes. It is a Korean device and the world-first dual-frequency monopolar RF system, combining 6.78 MHz and 2 MHz energy.
The forehead, cheeks, lower face, under-chin area and neck, as well as body areas. The device's shallow, middle and deep modes let the practitioner tailor depth by area.
Radiofrequency energy warms tissue in a controlled way at selected depths. This stimulates fibroblasts to produce new collagen, which firms and tightens the skin progressively.
No surgical downtime. Most patients return to normal activity immediately after treatment.
Barely. Most patients describe it as a warm hot-stone massage, around one to two out of ten. Cooling is built into the treatment tip and the energy is delivered in controlled pulses, so no numbing cream or injection is needed at any point.
Some tightening is visible early. The more significant firming builds over the following months as collagen production increases.
Typically six to eight months. Results are progressive rather than permanent, since skin continues to age, so most patients plan a maintenance treatment at that point. This is discussed at consultation.
Patients wanting firmer skin, a cleaner jawline and natural collagen support without needles or surgery. Suitability including implants and medical history is checked at consultation.
