Skin sags from deep down. XERF treats it there. The latest in radiofrequency lifting and tightening, straight from Korea to London.
XERF in London – Launching soon in the UK with DrMedispa. Pre-register now to be among the first to book.
Skin loosens as it ages. The jawline softens, jowls form, and the face can start to look more square than it once did. A surgical face-lift isn’t something most people want, so the question we hear most often is whether there’s a way to tighten and lift the skin without the pain, needles or recovery time.
XERF – already a hit in Korea – is made for exactly that. It’s a multi-level radiofrequency device that delivers energy into the superficial, middle and deep layers of the skin to stimulate collagen, with no numbing cream and no time off afterwards. It’s been a hit with celebrities worldwide, including Kim Kardashian, and patients have been travelling to Seoul to try it for themselves. Now, you won’t have to book that flight!
We’re bringing XERF to London at DrMedispa, and you can register now to be among the first to book for this summer.

Korean beauty is trending for the right reasons: patients want collagen stimulation and natural, subtle refinements, which XERF delivers
Energy is delivered across three skin depths, so tightening and lifting are treated at the level each area needs – including the SMAS if needed
Over 30 precise settings allow our practitioners to tailor XERF to your anatomy and treatment goals


XERF uses monopolar radiofrequency at two frequencies, 6.78 MHz and 2 MHz, to direct heat to the right depth in your skin. That heat targets water in the tissue, which encourages the skin to produce new collagen over the following weeks.
Comfort is part of the design. A cooling system (Advanced Integrated Cryogen Delivery) and Wave Fit pulses regulate the surface temperature while the energy works beneath the surface, so the treatment feels warm rather than uncomfortable. Because there’s no numbing step, sessions are also shorter than many comparable treatments.
The depth is matched to the area:
Most radiofrequency devices send energy to a single depth. XERF works at two frequencies, 6.78 MHz and 2 MHz, across three depths, so the forehead, the mid-face and the deeper tissue under the jaw can each be treated at the level that suits them in one session.
The other difference is comfort. Older RF treatments often need numbing cream first. XERF pairs its cooling system with Wave Fit pulses to manage the surface temperature as it works, so there’s no numbing step and sessions run shorter as a result.


We use XERF for lifting, tightening and collagen remodelling.
The most common treatments are:
Usually 45 to 60 minutes, depending on the areas treated. How many sessions you need depends on your skin and your goals, which we’ll talk through at your consultation.
The face, neck, jawline and décolletage, as well as areas on the body. We’ll confirm what’s suitable for you at your consultation.
No. There’s no numbing cream and no needles, so you can head straight back to your day afterwards.
It shouldn’t. Discomfort is minimal: the cooling system and Wave Fit pulses keep the surface comfortable while the energy works underneath, and most people describe the feeling as warm.
Typically 12 to 18 months. Most people keep their results topped up with a session roughly every six months, so twice a year.
Maintenance is usually two sessions a year, around six months apart. Your practitioner will set a schedule that suits your skin.
XERF adjusts to your skin in real time, so it works across a range of skin types and tones. Your consultation is where we check it’s right for you.
There’s no special preparation and nothing to recover from. We’ll give you any aftercare advice at your appointment.
Your skin can feel tighter soon after a session, and firmness tends to improve over the following weeks as collagen rebuilds. Results vary from person to person.
