Doctor-led FlexSure RF body sculpting in Marylebone, London. Non-invasive radiofrequency that reduces fat and tightens skin in 15 minutes. From £350.
Stubborn fat that survives every diet and every gym session tends to sit in the same few places, and that is exactly what FlexSure targets. This treatment suits patients who want to reduce those pockets and firm up mild skin laxity on the body, with no surgery and no time off. It works well on areas that have plateaued despite your best efforts.
The wrappable applicator moulds to any contour, there is no BMI restriction, and it is safe for all skin types, so it fits a wide range of body shapes. It is a strong choice if you want to refine your outline rather than lose overall weight.
FlexSure is a non-invasive radiofrequency body-sculpting treatment. A flexible applicator wraps around the area and warms the deeper tissue to reduce fat and tighten skin at the same time. Each session takes around 15 minutes and needs no recovery.
FlexSure is at its best contouring and firming stubborn pockets that have plateaued despite healthy eating and exercise, rather than as a weight-loss method.

FlexSure delivers controlled radiofrequency energy that gently warms the deeper layers of tissue. That heat prompts the body to break down stubborn fat cells and, at the same time, stimulates collagen so the overlying skin firms. The flexible applicator wraps right around the area, so the warmth reaches evenly in about 15 minutes. One comfortable session addresses both fat and skin laxity together, which is what sets a wrap-around radiofrequency device apart from spot-treatment tools.
Your FlexSure journey starts with a consultation at Dr Joney De Souza Clinic in Marylebone. Your practitioner assesses the areas that concern you, talks through your goals and confirms the treatment is right for you. Carried out by Dr Joney De Souza or a member of our clinical team. Your consultation is with Dr Joney De Souza or Dr Mattia Parducci.
You leave with a clear, personalised plan and a realistic idea of the course you are likely to need. In most cases no special preparation is required.
On the day, your practitioner cleanses the area and positions the flexible FlexSure applicator so it wraps around the contour being treated. The applicator conforms to the body, so it reaches areas that rigid devices tend to miss.
Preparation takes only a few minutes. You simply relax while everything is set up.
Your practitioner then runs the treatment, which takes around fifteen minutes per area. The wrappable applicator delivers controlled radiofrequency energy that gently warms the deeper layers of tissue.
Most patients describe the feeling as a warm, relaxing heat. You can unwind throughout the session.
The warmth encourages the body to break down stubborn fat cells and stimulates collagen, which firms the skin. Across your course this refines the contour and improves skin quality in the treated area.
The change is gradual, so it reads as natural rather than sudden. Each session builds on the one before.
FlexSure needs no recovery time, so you return to your normal day straight after the session. Any mild warmth or redness in the area settles quickly.
Your practitioner gives you simple aftercare guidance before you leave. You can exercise, work and socialise as usual.
Results develop progressively over the weeks of your course as the body processes the treated fat and collagen rebuilds. A course of around four sessions is recommended for the best result, with maintenance to sustain it.
Your practitioner sets realistic expectations for your area and goals. Pairing FlexSure with a healthy lifestyle helps keep the result looking its best.
From your first consultation through to your results, here is what to expect at our Marylebone clinic.

On the day, your practitioner prepares the area and carries out your FlexSure treatment, which typically takes around 15 minutes per area. Most patients find it comfortable and straightforward.
Your practitioner works methodically across the area for an even, natural result. You can return to your day straight afterwards.
Afterwards, any mild redness or tenderness settles quickly, with little to no downtime. Results build gradually over the weeks as your skin responds, looking natural rather than sudden.
Your practitioner gives you full aftercare guidance before you leave and advises on maintenance to sustain your result.
Body-contouring devices are widely available, but the outcome depends far more on the assessment behind the treatment than the machine itself. At Dr Joney De Souza Clinic every FlexSure session sits within a doctor-led setting with proper assessment and aftercare. Your practitioner confirms whether the treatment suits your goals and, where it helps, combines it with other body treatments for a better overall result.
You get honest guidance on what to expect rather than a one-size-fits-all package. That medical oversight is what makes the difference. Carried out by Dr Joney De Souza or a member of our clinical team. Your consultation is with Dr Joney De Souza or Dr Mattia Parducci.

FlexSure reduces fat and tightens skin, but it is often at its best as part of a wider plan. Many patients pair it with StimSure to build and define the underlying muscle, or with TempSure Firm for further skin tightening. Your practitioner can map out a combined body-contouring approach tailored to your goals, so each treatment does the job it is best suited to.

FlexSure raises common questions around which areas it treats, how many sessions you need and how it compares to other body treatments. The answers below cover what patients most often ask.
FlexSure is a non-invasive radiofrequency treatment that reduces stubborn fat and tightens skin on the body. At Dr Joney De Souza Clinic in Marylebone, its flexible, wrappable applicator conforms to your body to reach areas that rigid devices struggle with.
Each session takes around 15 minutes and needs no downtime. It suits any skin type, with no BMI restriction.
FlexSure works well on the abdomen, flanks, back, thighs, arms and other areas where stubborn fat and mild skin laxity sit together. The applicator curves to the body, so it treats hard-to-reach contours comfortably.
Your practitioner confirms the most suitable areas at your consultation. Many patients treat more than one area over a course.
Most patients have a course of around four sessions for the best result, spaced a couple of weeks apart. The exact number depends on the area and your goals, which your practitioner confirms after assessing you.
Results build gradually as the treated fat reduces and the skin tightens. A maintenance session can help sustain the outcome.
Most patients find FlexSure comfortable, describing it as a warm, relaxing sensation as the radiofrequency heats the deeper tissue. There is no downtime, so you can return to normal activities straight away.
Mild redness or warmth in the area settles quickly. It is a genuinely lunchtime-friendly treatment.
Results develop gradually over the weeks following your course as the body processes the treated fat and collagen rebuilds, so the change looks natural rather than sudden. Your practitioner sets realistic expectations based on your area and goals.
FlexSure refines your contour, but it is not a weight-loss treatment and will not fix significant skin sagging that needs a different approach. Pairing it with a healthy lifestyle helps maintain the result.
FlexSure works on fat and skin laxity together, while StimSure targets muscle tone and TempSure Firm focuses on skin tightening, so they are often planned together. Your practitioner will advise which combination fits your goals.
