What Is Exilis Body Treatment?
Exilis is a brand name for a radio frequency device, produced by BTL Aesthetics, that is used in aesthetic clinics for non-surgical body contouring and skin tightening. Some versions of the device combine radio frequency with focused ultrasound energy. Practitioners use it to address areas where skin appears loose or where localised pockets of fat are visible, such as the abdomen, thighs, arms, and flanks.
As part of the broader world of non-surgical body sculpting, Exilis sits alongside several other energy-based technologies. Understanding how it works helps you make an informed comparison when exploring your options.
Wumi Body & Face Studio does not offer Exilis. This article is educational. If you are interested in non-surgical treatments that use radio frequency and ultrasound technology, Wumi offers ultrasound cavitation and RF body sculpting as an alternative approach — see the section below for more detail.
How Radio Frequency and Ultrasound Work Together
Radio frequency (RF) works by passing electrical energy through tissue, which generates heat. When applied carefully to the skin and underlying fat layer, this heat can stimulate collagen fibres to remodel, which gradually improves skin firmness. The warmth also creates a localised environment that may help the body process the appearance of fat deposits over time.
Ultrasound, when used alongside RF, adds a mechanical disruption to the fatty tissue. The sound waves create microscopic vibrations that target the fat cell membrane. This is the same principle used in ultrasound cavitation, a technique that is widely available from trained therapists across the UK.
Exilis combines both energies in a single handpiece, which is one reason it became popular in clinical settings. The device also monitors tissue temperature to help the practitioner maintain energy within a therapeutic range.
What Areas Can Be Treated?
RF and ultrasound technologies are typically used on:
- Abdomen and waist — one of the most commonly requested areas for non-surgical body contouring
- Thighs and hips — where the appearance of cellulite and loose skin is a frequent concern
- Upper arms — for improving skin tone where the skin appears crepey or loose
- Back and flanks — to address stubborn areas that are resistant to changes in diet and exercise
- Jawline and neck — some devices, including Exilis Elite, have a facial handpiece for skin tightening
These are the same areas addressed by non-surgical options such as vacuum therapy, wood therapy, and RF body treatments available through mobile and studio-based therapists across the UK.
Who Might Consider Exilis?
Exilis and similar RF devices tend to appeal to people who:
- Want a non-surgical approach with no recovery time
- Are looking to improve the appearance of skin laxity rather than achieve dramatic fat reduction
- Have already made lifestyle changes and want to complement those with a contouring treatment
- Prefer a clinic-based technology with a medical-grade device
It is important to understand that Exilis is not a weight-loss treatment. Like all non-surgical body sculpting approaches, it is designed to improve appearance and skin tone, not to substitute for a healthy lifestyle. Results vary between individuals and build gradually over a course of sessions.
How Does It Compare to Ultrasound Cavitation and RF?
The table below shows how Exilis compares in principle to the techniques Wumi Body & Face Studio uses:
| Feature | Exilis | Ultrasound Cavitation + RF |
|---|---|---|
| Technology | RF + ultrasound combined | Ultrasound cavitation + RF (separate or combined) |
| Setting | Medical aesthetic clinic | Beauty studio or mobile therapist |
| Downtime | None | None |
| Session length | Typically 30–60 minutes | Typically 45–75 minutes |
| Course needed | Yes | Yes |
| Results | Gradual, vary individually | Gradual, vary individually |
Both approaches use heat and sound energy to improve the appearance of targeted areas. The key difference lies in the clinical setting, the specific device, and the practitioner’s training. Neither guarantees the same outcome for every person.
Non-Surgical Alternatives Available at Wumi Body & Face Studio
Because Wumi does not offer Exilis, clients who are researching RF and ultrasound body treatments may find the following services relevant:
Non-surgical fat reduction at Wumi’s Dartford studio or via her mobile service uses ultrasound cavitation and radio frequency — technologies that target the same tissue as Exilis using similar principles. These are combined with other techniques such as lipo laser and vacuum therapy to create a tailored treatment plan.
Non-surgical body sculpting sessions address the appearance of localised fat and skin texture across the abdomen, thighs, buttocks, arms, and back. Treatments are available at the studio in Dartford, DA1, or via Wumi’s mobile service covering Kent, all 33 London boroughs, and Essex.
Non-surgical body contouring focuses on shaping and defining the body’s silhouette without surgery, combining RF with manual and mechanical techniques.
If you are unsure which approach suits your goals, a consultation at Wumi Body & Face Studio is a practical first step. Toyin (Wumi) has ten years of experience and holds CPD-accredited certification through Curvology Academy, so you can expect an honest, informed conversation about what non-surgical treatments can and cannot do for you.
What to Ask Before Any RF Treatment
Whether you are considering Exilis or any other RF-based treatment, these are sensible questions to put to the practitioner:
- What device do you use, and what training have you completed on it?
- How many sessions are included, and what is the recommended interval between them?
- What results should I realistically expect for my body type and starting point?
- Are there any contraindications I should know about (for example, certain metal implants or medical conditions)?
- Is the treatment suitable alongside any medications I take?
A practitioner who answers these questions clearly and without overpromising is a good sign. Be cautious of guarantees or dramatic before-and-after claims — reputable UK practitioners follow ASA and CAP guidelines, which prohibit misleading results claims.
Finding RF Body Treatments in the UK
If Exilis specifically is what you are researching, look for clinics that clearly state their practitioners are trained on the device and hold appropriate insurance. In the UK, aesthetic treatments using medical-grade devices are increasingly subject to scrutiny, and the government has been moving towards tighter regulation of the sector.
For non-surgical body sculpting that uses comparable RF and ultrasound technology — without the clinical setting or price point of a medical device clinic — explore therapist-led options like those offered at Wumi Body & Face Studio.

Non-surgical treatments have no downtime, but results build gradually and vary between individuals. Not a weight-loss or medical service. A consultation and suitability check are required; you must be 18 or over.
