How Exilis Works
Exilis delivers radiofrequency energy that warms the deeper dermis to a therapeutic temperature of around 40 to 42 degrees. Two things happen at once. First, the existing collagen fibres contract in the heat, giving an immediate tightening. Second, the controlled warmth stimulates your fibroblasts to build new collagen and elastin over the following weeks, for firmer, smoother, more toned skin.
The handpiece keeps the surface of the skin comfortable while delivering the energy where it is needed, so the skin is tightened from within with no break to the surface and no downtime.
Exilis firms and tightens the skin. It is the tightening partner to the volume and contouring work in your plan, which is why it pairs so well with treatments that reduce fat or lift the deeper structure.
Where It Works
Common Treatment Areas
Exilis suits areas of the body where the skin needs firming, often where volume has reduced or skin has softened with time.
Firming and tightening loose or softened skin across the tummy, often alongside contouring work.
Smoothing and tightening around the waistline as the area reduces and reshapes.
Tightening the softer skin on the back of the upper arm for a firmer, smoother line.
Firming crepey skin on the inner thigh and above the knee, areas that respond well to warmth.
During Treatment
What to Expect
Most people describe Exilis as a hot stone massage. The handpiece glides over the area delivering steady, comfortable warmth. Your practitioner monitors the temperature throughout to keep it both comfortable and effective.
The area may feel warm and look slightly pink for a short while. There is no downtime and you can return to your day immediately, with nothing to plan around.
After Treatment
Your Results Timeline
Mild warmth or pinkness that settles quickly. Some people notice a subtle, immediate firmness from the initial collagen contraction.
Tightening builds session on session as collagen responds. Exilis is designed as a course rather than a one off for exactly this reason.
New collagen keeps maturing for weeks to months after your final session, so results continue to develop after the course ends.
Results are long lasting, though natural ageing continues. Occasional top up sessions help keep skin firm over time.
Results
What Results to Expect
Exilis gives a gradual, natural improvement in firmness and skin tone. Some firmness shows early from collagen contraction, with the fuller result building over the weeks and months as new collagen matures.
It is a skin tightening treatment, so it is at its best as part of a plan, helping the skin retract neatly as an area is contoured rather than working in isolation.
Exilis and HIFU work at different depths, which is why they pair so well. Exilis warms and tightens through the dermis, while HIFU reaches the deeper structural layer beneath. Together they firm the area more completely than either could alone.
Maximising Your Outcome
What Affects Your Results
Radiofrequency works through water, and collagen is built from it. Staying well hydrated genuinely improves how well you respond.
Collagen is built from amino acids. Steady protein and a nourishing diet give your body the raw materials to rebuild.
The tightening builds session on session. Attending your full course as planned gives the best, most even result.
Smoking impairs collagen production and skin repair, and noticeably reduces results.
Non Invasive vs Surgical
How It Compares to Surgery
No anaesthesia, no incisions, no scarring and no downtime. Comfortable, warm sessions with gradual, natural firming. Best for mild to moderate skin laxity.
Anaesthesia, incisions, scarring and weeks of recovery, with the ability to remove excess skin. Immediate, dramatic results. Best for significant loose skin.
Exilis is ideal if you want firmer skin with no downtime and a result that builds gently over a course. It is not a substitute for surgery where there is significant excess skin, but for firming and toning mild to moderate laxity it is a genuine, lower commitment alternative.
Safety
Who Is Suitable
Exilis suits people who want firmer, tighter skin with no downtime, particularly as part of a body contouring plan where the skin needs to retract as volume reduces. Your practitioner confirmed your suitability at consultation.
Exilis is not suitable, or needs extra care, if you are pregnant or breastfeeding, have a pacemaker, defibrillator or other electrical implant, have metal implants in the treatment area, have an active cancer, or have an active infection or broken skin in the area. Always share your full health history so we can keep your treatment safe.
Common Questions
Frequently Asked Questions
No. Most people find it relaxing, similar to a warm massage. Tell your practitioner at any point if the warmth feels too strong and they will adjust it.
Radiofrequency works through the water in your skin. Well hydrated skin heats evenly and responds better, which is why your prep guide puts hydration first.
Exilis is delivered as a course rather than a one off, since collagen builds gradually. Your personalised plan sets out exactly how many sessions are included for you.
Some firmness is visible early from collagen contraction, with the fuller result developing over the weeks and months as new collagen matures.
