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.

From start to finish I felt really well looked after. The clinic is clean and has a calm, soothing atmosphere, and Dr Hass took the time to answer every question I had, so I felt completely at ease all the way to the end. The XERF treatment itself was surprisingly relaxing, with no pain at all!! I’m already starting to look and feel refreshed, and I know the full results build up over time, so I’m excited to see the final effect. I’d recommend this clinic to anyone for its professionalism and genuine attention to patient care!!!

I went to Dr Hass over a week ago for cheek and chin filler and I love the results! Dr Hass took the time to listen to my concerns during the consultation and ensured the results were natural, as I wanted them. I was a bit nervous going into it but he was very professional, personable and kind and made me feel comfortable during the appointment- would highly recommend!

I had my Endolift treatment with Dr Hass and couldn’t be happier with my experience. From the initial consultation through to the treatment itself, I felt reassured and well looked after. Dr Hass was professional, knowledgeable and took the time to explain everything clearly, which made me feel at ease throughout. I wanted a subtle, natural-looking result rather than anything drastic, and I felt confident that Dr Hass understood exactly what I was hoping to achieve. The whole experience was positive, and I’m really pleased with the care and attention I received. I would highly recommend Dr Hass to anyone considering Endolift and looking for a professional, reassuring experience.

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.
