Mayfair’s First Surgeon-Led XERF Laser Clinic

Experience the world’s first multifrequency RF treatment. XERF tightens your skin at every layer, with zero downtime.

Trusted by over 10,000 patients across London.

What is XERF?

XERF (eXtra Enhanced Radiofrequency) is an advanced, non-invasive skin tightening treatment born from Korean skincare innovation that uses dual-frequency RF energy to stimulate collagen and elastin production deep within the skin. XERF is the first device of its kind to simultaneously target multiple tissue depths in a single session.

By delivering energy at two distinct frequencies, XERF reaches the superficial dermis, mid-dermis, and deep SMAS fascia — the structural layer addressed in a surgical facelift — all without incisions, numbing cream, or recovery time. Integrated cryogen cooling protects the skin’s surface throughout, making the treatment comfortable from start to finish.

XERF is ideal for those who:

  • Notice early skin laxity or jawline softening and want a defined, natural-looking lift
  • Want to tighten and contour without surgery, needles, or downtime
  • Are looking for a treatment that works across all skin tones, year-round

Before & Afters

Subtle refinement achieved through precision, proportion, and restraint. At Dr Hass Clinic, no two results are ever the same.

6 reasons patients choose XERF Laser

No other non-invasive device does what XERF does. Here’s why our patients choose it.

  • Triple-depth treatment: The only RF device to reach all three skin layers (dermis, mid-dermis, and SMAS) in a single session.
  • Real structural lift: It heats the SMAS fascia — the same layer addressed in a surgical facelift.
  • No pain. No numbing: Built-in cryogen cooling keeps the surface comfortable while the RF works deep.
  • Zero downtime: Walk out and get on with your day.
  • Safe for all skin tones: RF energy responds to tissue, not pigment. No exceptions.
  • Adaptive delivery: The device reads your skin in real time and adjusts energy depth accordingly.

Your XERF Journey: Step by Step

What XERF Does and Doesn't Treat

XERF and fat reduction treatments are often mistaken for one another, yet they work on entirely different tissue with entirely different results. Understanding the distinction ensures your treatment plan matches your goal precisely.

  • XERF tightens skin. Radiofrequency energy remodels collagen within the dermis and SMAS fascia, firming and lifting tissue that has lost its structural support.
  • XERF does not reduce fat. It has no effect on the adipose layer beneath the skin, regardless of intensity or number of sessions.

The two concerns are frequently mistaken for each other because both are addressed with non-surgical, walk-in-walk-out treatments. But excess volume and loose, lax skin are different problems requiring different solutions:

  • Excess fat with good skin elasticity — treated with fat dissolving alone.
  • Loose or crepey skin with minimal excess fat — treated with XERF alone.
  • Both concerns present together — most effectively addressed with fat reduction first, followed by XERF to tighten the skin left behind.

Why Choose Dr Hass Clinic?

XERF delivers results proportional to the expertise of the practitioner.

  • All treatments are carried out by Dr Hasaneen Al Janabi, a GMC-registered doctor and Member of the Royal College of Surgeons, trusted by over 10,000 patients.
  • Dr Hasaneen is an award-winning aesthetic practitioner with advanced training in energy-based skin tightening devices.
  • Each XERF treatment plan is completely bespoke, tailored to your facial structure, skin type, and rejuvenation goals.
  • The clinic uses the authentic FDA-cleared XERF system — not a lower-grade alternative.
  • Our Mayfair clinic provides a discreet, luxury setting designed for comfort, privacy, and clinical precision.

FAQs

What makes XERF different from Thermage or Ultherapy?

Thermage uses a single frequency targeting mainly the deep dermis; Ultherapy uses ultrasound focused on the SMAS. XERF combines two RF frequencies simultaneously, reaching all tissue depths in one session. The result is more comprehensive remodelling than either device alone, without their associated discomfort or downtime.

Is XERF Laser painful?

Most patients describe it as a warm, comfortable sensation throughout. Built-in cryogen cooling continuously protects the skin’s surface, so no numbing cream or anaesthetic is needed.

How many sessions will I need?

Many patients achieve excellent results from a single session. Those with moderate laxity may benefit from two or three sessions, spaced four to six weeks apart. Dr Hasaneen will confirm the right plan at your consultation.

When will I see results, and how long do they last?

Some improvement is visible immediately. The most significant results develop over six to twelve weeks as new collagen matures, with further tightening continuing for up to six months. Results typically last 12 to 24 months.

Is XERF suitable for all skin tones?

Yes. RF energy responds to tissue properties, not skin pigment, making XERF safe and effective across all skin tones — year-round.

What is the downtime after XERF?

There is none. You may experience mild redness or warmth for a few hours, which resolves on its own. You can return to work, exercise, and social activities straight away.

Can XERF be combined with other treatments?

Yes. XERF pairs well with anti-wrinkle injections, dermal fillers, and medical-grade skincare. Where clinically appropriate, Dr Hasaneen will recommend a combination protocol for a cohesive, natural result.

What are the risks of XERF?

XERF has a strong safety profile. Temporary redness, mild swelling, or warmth are the most commonly reported effects, all of which resolve quickly. Serious adverse events are rare. Dr Hasaneen will discuss your individual risk profile in full at consultation.

I recently went to Dr. Hass at Dr. Hass Clinic for an Endolift treatment, and I honestly couldn't be happier with the results! I had quite a bit of sagging skin, especially around my neck and lower face. The moment the procedure was done, I could immediately feel the tightening effect. The results were amazing right away the sagging on my neck completely disappeared, and my facial contours were lifted instantly. Dr. Hass is wonderful, so kind, and extremely professional. He explained everything in detail and took his time to focus precisely on the sagging areas where I needed it the most. I am so satisfied with my experience, I will definitely come back in the future, and I highly recommend him to anyone struggling with similar issues. He is truly one of the best, and I am so glad I found him and chose him!

I had my nose filler done by Dr. Hass, and I couldn’t be happier with the results! His knowledge, expertise and attention to detail were evident straight after the treatment. He understood exactly what I wanted to achieve and delivered the results I was hoping for. He also took the time to guide me through the process and advise me on the best approach to suit my nose and desired outcome. I’m extremely happy and satisfied with my results and would highly recommend Dr. Hass to anyone considering aesthetic treatments.

A very good experience. Dr Hass was professional, thorough and took the time to assess my face properly. The face mapping was very detailed, everything was explained clearly, and the recommendations felt considered rather than rushed. I felt very comfortable throughout.

I am a lady in my early 50s I was very confused to choose a clinic that can remove my double chin which was really annoying me and making me lose my confidence. I finally found Dr. Hass clinic. I am a person who doesn’t like surgeries or injections.. I was very worried but Dr Hass was a very experienced professional doctor who made me feel comfortable and relaxed. I personally didn’t feel any pain and when I saw the result I was amazed with the beautiful change … No more double chin 🥹🥹 It’s very important for all women to invest in their health and beauty.. I strongly recommend Dr Hass clinic and I would love to make another visit for different treatments 😊 Dr Hass you really changed my life by increasing my self confidence thank you so so much for everything 🥹🙏🏼🌹

I’ve been coming to Dr Hass for a long time now and I honestly wouldn’t trust anyone else with my filler. He always makes me feel completely at ease and really takes the time to listen to what I want, while also giving genuinely helpful and honest advice. He’s brilliant at what he does, couldn’t recommend him enough!

I visited Dr Hass for dermal fillers and it was my best experience to date. Dr Hass took time during the consultation to really ask questions to understand my needs and make the best recommendations for me to achieve my desired results. He was honest and personable and even advised me against treatments I thought I needed due to seeing others have these procedures online. He really cared about my results and being satisfied over anything else. I was nervous but he put me at ease and the results are amazing. Cannot recommend the clinic enough and I will be back!

Endolift A huge thank you to Dr. Haas! I had a big issue with sagging skin, especially on my neck, so I decided to get an Endolift for my face with an extended neck treatment. I saw the results immediately after the procedure—my skin was tightened, my facial contours were much more defined, and everything looked so beautiful and natural. I am extremely satisfied, the clinic is clean and gorgeous, and everyone there is so kind. Dr. Haas is truly one of the best doctors, and I highly recommend him to everyone!

Lips I would thoroughly recommend Dr Hass and his clinic. He is incredibly thorough, professional and, most importantly, honest in his approach. Having visited a number of different clinics over the years, what really sets Dr Hass apart is his focus on achieving a softer, fresher and more natural look rather than making you look “done”. He has completely transformed years of previous lip filler for me, and my lips already look amazing — beautifully natural and so much better balanced. I’ve had so many people notice the difference and comment on how good they look. I couldn’t be happier with the results and wouldn’t hesitate to recommend him.

I spent years looking for an effective treatment for my jawline and came across Dr Hass's clinic on instagram. I am extremely happy with the results of endolift and a mini liposuction. The service was exceptional from beginning to the after care. Dr Hass always responds to queries and gives appropriate advice. I would highly recommend his services.

Would highly recommend the Dr Hass Clinic. From booking my initial consultation right through to aftercare, every interaction has been quick, easy and professional. After having Endolift on my face with exceptional results, I had no hesitation in booking an Endolift body treatment for my thighs. Due to the amount of loose skin, I had always assumed surgery was my only option. I didn’t want to trade sagging skin for scars, and I also didn’t have the budget or the time for surgery and a lengthy recovery. I was therefore over the moon when Dr Hass explained that I could achieve visible skin tightening results with Endolift. I’ve just had the treatment, so I’m now really excited to see the results develop! The level of care, expertise and attention throughout has been brilliant. I’m particularly self-conscious about my thighs, but Dr Hass made me feel completely at ease and comfortable throughout the consultation and treatment. The treatment itself was also practically pain-free. I genuinely wouldn’t hesitate to recommend Dr Hass and his clinic. He clearly knows his stuff, takes great care of his patients and, as an added bonus, is actually a really cool guy to spend a few hours, I’m now a country music fan too!
