Price and sessions
How much does Exilis cost?
We set out the price of Exilis in writing at a free consultation, and we price match any comparable written quote. Consultations and follow-up reviews are free whatever you decide. The price depends on the areas and the number of sessions.
How many sessions, and how often?
Usually four weekly sessions of about 30 minutes per area, as the published series ran them; the face study used three. The plan is set at the free consultation, and the studies read the result one to three months after the last session.
How long until I see results?
The skin firms and the measurement falls gradually over the course, and the studies read the result one to three months after the last session.
Results
Is Exilis effective for the face?
Exilis is used to tighten loose skin on the face, and the small studies found a visible, modest improvement that builds over a course. In a 30-person Exilis study every item improved after three weekly sessions, significantly only where the starting grade was the worst, for fat loss, hollows and puffiness. In a 34-person study of a combined radiofrequency and ultrasound device, blinded assessors picked out the after photograph in over 90% of cases. There is no sham-controlled face trial, and we say so.
Is Exilis good for skin tightening?
BTL markets it for skin tightening on the face and the body. Heat makes existing collagen contract and prompts new collagen over the following weeks. The Exilis clearances in the US are worded for wrinkles, and the tightening is measured in the studies rather than named on the label.
How long do results last?
The studies read their results one to three months after the last session, and nothing published measures beyond that. In our experience the firming holds as long as your weight and your skin's ageing allow, and a maintenance session is a choice some people make at the review rather than a schedule.
Does Exilis work, and is it worth it?
The published series, with a combined radiofrequency and ultrasound device, found a measurable fall in circumference on the abdomen, thighs and arms, and on the face a modest firming. In our experience it is worth it for someone who wants a gradual change with no downtime; for a large bulge or heavy loose skin the doctor will say if something else is the better route.
Does Exilis remove belly fat?
It reduces the measurement rather than removing fat: in a 64-person series with a combined radiofrequency and ultrasound device, abdominal circumference was significantly lower a month after the fourth session. Exilis is not a weight-loss treatment.
Consultations and follow-ups are free
Comfort and safety
Is Exilis painful?
Most patients find it comfortable. You feel warmth that builds, and we adjust the level with you; in a published study of a combined radiofrequency and ultrasound device, comfort was rated 4.1 out of 5. Tell the doctor straight away if an area feels too hot.
What are the side effects, and is Exilis safe?
Redness and warmth for hours and tenderness for up to a day. No adverse events were recorded in the published series that report it. The seven reports naming Exilis to the US regulator between 2011 and 2021 include a nodule, infections at the navel and stomach pain, with no burn. A US consent form lists blistering and, rarely, scarring, which is why the skin temperature is watched throughout.
Can Exilis cause fat loss in the face?
No study has measured it, and the doctor goes through it with you at the consultation. In our practice the face sessions are planned for the skin and adjusted to your face.
Who should not have Exilis?
Anyone with a pacemaker, an internal defibrillator or another internal electronic device, metal implants in or near the area, pregnancy or breastfeeding, or an active skin infection or inflammation. We also screen for the conditions on a US consent form at the consultation.
Areas and comparisons
Which areas can be treated?
Every area the device is used on. The abdomen, the thighs, the upper arms and the face have studies. The intimate area has one small series of 17 women, on the labia. The neck, the décolletage, the flanks, the buttocks, the knees and the hands have none, so the doctor advises at the consultation what to expect for those.
Is Exilis better than HIFU?
Different. HIFU delivers focused ultrasound to set depths in lines, in our experience usually one session that feels sharper; Exilis heats the whole area in passes over a course of gentler sessions. No trial compares them. In our practice Exilis suits the body and someone who wants comfortable sessions; Ultherapy, which we provide, suits lift at the brow and neck.
Before and after
What should I avoid before a session?
In our practice, sunburn and fake tan on the area, and a heavy meal just before. Tell the doctor about any metal in the area, any implant and any medicine you take.
What should I do after a session?
In our practice: go back to your day. Drink water, keep the skin clean, avoid very hot baths and hard exercise on the day if the area feels warm, and use sunscreen on a treated face. Call us about any blister or a patch that stays tender.
