What to Expect from the New No-Downtime Skin Tightening Treatment in London

London’s aesthetics scene rarely sits still for long, but even by the capital’s standards, the arrival of XERF has generated an unusual amount of quiet anticipation among skincare insiders.

Next week, Dr Hass Clinic in Mayfair becomes one of the first clinics in the capital to offer XERF Laser in Central London, giving Londoners early access to a device that’s been generating buzz across the aesthetics industry for its ability to do something few non-surgical tools have managed before: genuinely lift and remodel skin at a structural level, without a single incision.

At a glance:

• What it is: a dual-frequency radiofrequency treatment reaching the dermis, mid-dermis and SMAS fascia in one session
• Downtime: effectively none
• Sessions: 45 minutes to 90 minutes, often just once
• Results: build over 3 to 6 months, lasting 12 to 24 months
• Where: Dr Hass Clinic, Mayfair, one of the first UK clinics to offer it

So what actually is XERF?

The name stands for eXtra Enhanced Radiofrequency, and it traces back to Korean skincare research, a part of the world that has a habit of arriving at advanced, tech-heavy treatments a good few years before everyone else catches up.

What sets it apart from the radiofrequency devices most of us have already heard of is that it fires two separate frequencies into the skin at the same time. Instead of picking one depth and staying there, it works through the superficial dermis, down into the mid-dermis, and then reaches the SMAS fascia, the very layer a surgeon would be pulling and stitching in an actual facelift.

That’s the part that makes practitioners sit up. Getting to that layer without cutting anything is a serious claim, and it explains why there’s genuine curiosity around this device rather than the usual shrug that greets most new lasers. Cryogen cooling runs throughout the treatment, so the surface of the skin stays comfortable while the energy does its work underneath. Most people describe it as warm rather than painful, a world away from the older generation of RF or ultrasound machines some of us have grimaced through in the past.

What actually happens during a session

A session typically runs somewhere between 45 minutes and an hour and a half, depending on how much of the face or body is being treated. There’s no injecting, no cutting, no numbing cream. The handpiece simply moves across the skin, and the device adjusts how deep it’s sending energy as it reads the tissue in real time, a small detail that separates it from older, one-setting-fits-all machines.

Downtime, in the traditional sense, barely exists. You might look slightly flushed for an hour or two afterwards, but that’s about it. Most people head straight back to work, the gym, or dinner. For anyone juggling a packed London schedule, that alone is arguably the biggest selling point, before you even factor in the results.

Those results ask for a little patience. Nothing dramatic happens overnight. Skin needs time to respond and start producing new collagen, so the real improvement tends to build gradually over three to six months. Once it settles in, it’s said to last somewhere between twelve and twenty-four months before a top-up session becomes worth considering.

What it won’t do, and why that matters

One thing that gets muddled a lot with treatments like this: XERF tightens skin, it does not touch fat. If there’s a stubborn pocket of fat sitting under otherwise firm skin, this isn’t the tool for that job, and no amount of radiofrequency energy is going to shift it. The confusion tends to happen because both problems are treated with the same kind of walk-in, walk-out, no-surgery appointment, so people lump them together even though they’re solving completely different things.

As a rough guide:

• Good skin elasticity with excess fat usually points towards fat-dissolving treatments
• Loose or crepey skin with relatively little fat underneath is where XERF earns its keep
• Both issues present at once typically means treating the fat first and tightening afterwards

It’s a conversation worth having directly at a consultation rather than assuming the answer either way.

Why Mayfair, and why now

Bringing a treatment like this to London before most other clinics have got their hands on it fits a pattern that’s familiar around Mayfair and Harley Street, where being first with credible new technology functions almost as its own kind of currency. The clinic is led by Dr Hasaneen Al Janabi, who is GMC-registered and a Member of the Royal College of Surgeons. Anyone considering treatment with any practitioner, not just here, can check that kind of registration for themselves on the GMC’s online register, a habit worth getting into regardless of which clinic you end up choosing.

Dr Hass Clinic says it has treated more than 10,000 patients across its facial and body treatments to date, and has picked up a fair amount of press coverage along the way in outlets including Vogue and GQ, mostly around broader skincare and aesthetics topics rather than XERF specifically.

Location does matter here, though not for the reasons a search engine cares about. The clinic sits just off Hill Street, a short stroll from both Bond Street and Green Park, tucked among the townhouses and boutiques that make this pocket of the capital feel distinct from the rest of London’s aesthetics scene. It’s the kind of setting patients notice the moment they walk in: discreet, unhurried, more drawing room than clinical waiting area, which suits a treatment built around subtlety rather than dramatic before-and-afters.

Who’s it really for

Going by how the treatment is being described, it seems aimed at people who notice their jawline softening or their skin generally losing its firmness, rather than dealing with significant excess volume. It also suits anyone wanting a visible, natural-looking lift without going anywhere near surgery, needles or downtime, or who has already tried the skincare-and-serums route without getting the structural change they were hoping for. Because radiofrequency responds to tissue rather than pigment, it’s also being positioned as suitable across a full range of skin tones, something not every energy-based device can claim.

None of that replaces an actual consultation, though. A decent practitioner will tell you honestly if you’re not a good fit for a particular treatment, and that conversation is worth having before booking anything.

Where this fits into the bigger trend

Skin tightening has quietly become one of the busiest corners of aesthetic medicine over the last few years, largely because people have moved away from wanting surgery and towards wanting real, visible change without the recovery time that comes with it. XERF landing in London, and landing in Mayfair first, says something about where that appetite is heading: not just surface-level tweaks, but treatments trying to address the actual structural changes that come with getting older.

Whether it lives up to its “facelift without the surgery” reputation will become clearer over the coming months, once more clinics have it in and more before-and-afters start doing the rounds. For now, it’s arriving with more genuine interest behind it than most new devices manage, and Mayfair will be among the first places in the country to find out whether that interest is deserved.
