XERF London: Skin Tightening at Harley Street

XERF is a needle-free skin tightening treatment for loose skin on the face, jawline and neck – no injections, no surgery and no planned downtime.

It is now available at Dr Elif Clinic, 54 Harley Street. Every treatment starts with a doctor-led assessment of your skin and facial structure, so the plan is built around your face rather than a one-size-fits-all setting.

What is XERF?

XERF uses radiofrequency energy to gently warm the deeper layers of the skin. That warmth makes existing collagen tighten and encourages your skin to build new collagen over the following weeks – so the skin gradually becomes firmer and better defined.

The energy passes through the surface of the skin, so there are no needles, no cuts and no marks afterwards. XERF is not a laser and it is not microneedling. Results look natural: you, a little firmer and more refreshed, rather than a different face.

Treatment areas

The jawline and neck are the most popular areas: XERF helps sharpen the jaw contour, tighten the skin under the chin and smooth the neck – the changes people notice most in photos and in profile.

What to expect at your appointment

1. Consultation. We look at your skin, facial structure, medical history and what you would like to change – and confirm XERF is the right choice.
2. Your plan. Treatment areas, depth and energy levels are chosen for your face. No numbing cream is usually needed.
3. The treatment. The handpiece glides over each area for around 45–60 minutes. You will feel waves of deep warmth; built-in cooling keeps the surface comfortable.
4. Afterwards. You can go straight back to work or your day. Mild redness or warmth may last a few hours; tenderness or slight swelling is possible but temporary.

When will I see results?

Some people notice a little tightening straight away, but the real change is gradual. Most patients see results from 4–6 weeks, with the full effect building over 3–6 months as new collagen forms. Depending on your skin and goals, we usually recommend 1–3 sessions.

How does XERF work?

XERF combines two radiofrequency frequencies (6.78 MHz and 2 MHz) with three depth settings, so energy can be directed to the right layer for each area – from the dermis down to the SMAS layer, the same supporting structure addressed in a surgical facelift. Real-time feedback and built-in cooling keep the heating controlled and comfortable.

The controlled warmth does two things: it makes existing collagen fibres contract, and it switches on the skin’s repair cells to produce new collagen and elastin. That is why results keep improving for months after the session.

XERF vs HIFU, Endolift and Morpheus8: which skin tightening is right for you?

Patients often ask us whether they should have XERF, HIFU, Endolift or Morpheus8. All four tighten skin by heating the deeper layers so that collagen contracts and new collagen is produced – the difference is how the energy gets there, how invasive that is, and which concern each one is best at. We offer all of them at 54 Harley Street, so our recommendation is based on your skin, not on a single device. XERF stands out as the only one of the four that treats the whole face, the eye area and the neck in a single non-invasive session – no needles, no anaesthetic, no downtime – reaching as deep as the SMAS layer while you simply lie back.

XERF vs HIFU

These are the two non-invasive options: neither uses needles and both are done through the surface of the skin. HIFU (Ultraformer MPT) uses focused ultrasound to create tiny points of heat at set depths, which trigger the skin’s repair response. XERF uses two radiofrequency frequencies with three depth settings, so the energy can be directed anywhere from the dermis down to the SMAS layer, with real-time feedback and built-in cooling keeping the heating controlled and comfortable. In practice we tend to suggest HIFU for very mild laxity or maintenance, and XERF when you want a more noticeable firming of the whole face – cheeks, eye area, jawline, under-chin area and neck – in one session, without needles or downtime. Both can be repeated, and both are agreed at consultation.

XERF vs Endolift

This is the most common question we hear, and the two treatments do different jobs. Endolift is a targeted, minimally invasive laser treatment: a fibre thinner than a hair is placed under the skin, under local anaesthetic, and it is used mainly on the lower face – the jawline, under the chin and the neck – where it also reduces small pockets of fat. That makes it the right choice when a soft jawline or double-chin area is caused by fat as much as by loose skin. XERF is the whole-face treatment: in one 45–60 minute session it firms the cheeks, the mid-face, the area around the eyes, the jawline and the neck together, entirely from the surface, with no needles, no anaesthetic and no planned downtime. It does not remove fat – it tightens and lifts skin – so if your concern is that your face and neck are starting to lose firmness overall, XERF gives you the more complete result and lets you walk straight back into your day. If the main issue is fat under the chin, Endolift (or Endoskin®, performed by Dr Hasan Benar) is the better tool, and for some patients we combine the two: Endolift for the fat under the chin, XERF for the whole face and neck.

XERF vs Morpheus8

Both use radiofrequency, but they deliver it very differently. Morpheus8 is fractional RF microneedling: fine needles carry the energy into the skin at adjustable depths, which is why it excels at skin texture – acne scarring, enlarged pores, fine lines and sun damage – with some tightening as a bonus, and at our clinic it is combined with exosomes to support healing. XERF delivers RF through the intact surface with no needles, so it is the choice when your main concern is firmness rather than texture, and when you want no downtime at all. A simple way to think about it: if you would describe your concern as “my skin looks tired, scarred or uneven”, start with Morpheus8; if it is “my jawline and neck feel looser than they used to”, start with XERF. Some patients benefit from both, at different times.

None of these is “best” for everyone – we recommend the one that fits your skin and goals, not the newest device. If you are unsure, that is exactly what the consultation is for.
