Doctor-led StimSure EMS muscle sculpting in Marylebone, London. Build, tone and define muscle without surgery or downtime. From £100 per session.
You train, you watch what you eat, and the definition still is not showing the way you want it to. StimSure at Dr Joney De Souza Clinic in Marylebone is built for exactly that gap. It suits anyone who wants stronger tone, a firmer core or more shape through the abdomen, buttocks, arms or thighs, without surgery and without downtime. It works well if you already exercise and want an extra edge, and equally well if you are looking to kick-start muscle definition from a lower base.
StimSure works the muscle itself rather than the fat around it, so it sits naturally alongside fat-reduction treatments for a fuller body-contouring plan. If you have soft, undefined upper arms and want them tighter, this is one of the treatments to ask about at consultation. StimSure is at its very best building and defining the muscle you already have, so results show beautifully when your general health and activity support them. If fat reduction is also a priority, we can pair it with a fat-reduction treatment for a fuller body-contouring plan.

StimSure delivers targeted electromagnetic energy that triggers strong, involuntary muscle contractions in the area being treated. These contractions go far beyond anything you could produce voluntarily in the gym, which is what prompts the muscle to strengthen, build and tone across a course of sessions. Each treatment works the muscle deeply while you lie back and relax, and there is no recovery time afterwards.
The change is gradual and looks natural, building over your course and the weeks that follow rather than appearing overnight. It targets muscle and not fat, so StimSure pairs well with fat-reduction treatments when your goal is both a leaner and a more defined shape.
Your StimSure journey begins with a consultation at our Marylebone clinic, where your practitioner assesses your goals and starting point and confirms the treatment is right for you. Your consultation is with Dr Joney De Souza or Dr Mattia Parducci, who explains what to expect and plans the course you are likely to need. In most cases you need no special preparation. You leave with a clear, personalised plan.
On the day, your practitioner positions the StimSure applicator over the muscle group you are targeting, such as the abdomen, buttocks, arms or thighs. The setup is quick and comfortable, and you stay fully clothed or lightly covered as appropriate. You simply relax while everything is prepared.
Your practitioner then runs the session, which takes around thirty minutes. StimSure delivers targeted electromagnetic energy that triggers strong, involuntary muscle contractions far beyond what you could achieve voluntarily. You feel intense but tolerable contractions, a little like an intensive workout, while the device does the work.
These powerful contractions prompt the muscle to strengthen, build and tone over your course of sessions, improving definition and core strength in the treated area. The change is gradual, so it looks natural, and each session builds on the last.
StimSure needs no recovery time, so you can return to your day straight away. Some patients feel mild muscle fatigue afterwards, much as they would after exercise. Your practitioner gives you simple aftercare guidance before you leave, and you can work, train and socialise as usual.
Many patients feel a difference in muscle tone within a few sessions, with visible definition building over the full course and the weeks afterwards. Your practitioner recommends a course of around six sessions, with maintenance to sustain the result, and sets realistic expectations for your area and goals. Combining StimSure with a healthy lifestyle keeps your result looking its best.

There is little to no downtime, and any mild muscle fatigue settles quickly, much as it would after a hard workout.

You receive honest guidance on realistic results rather than a fixed package, which is what sets the clinic apart.
That measured approach runs through everything the clinic does. As Dr De Souza puts it:

StimSure is priced per session, with a course of six recommended for visible toning, and every plan includes a consultation. Pricing varies slightly by area, with larger areas such as the abdomen and full thighs priced accordingly. Your practitioner confirms your plan and cost before treatment begins.
| Treatment | Single (£) | Course of 6 (£) |
|---|---|---|
StimSure (most areas) | 100 | 550 |
Abdomen & lower back / full thighs | 170 | 980 |
StimSure builds and defines muscle, so it works beautifully alongside a treatment that targets stubborn fat. Pairing the two gives a more sculpted, defined result than either delivers alone. FlexSure fat reduction is one option your practitioner may suggest, and a combined fat-and-muscle plan is agreed at consultation. If fat reduction is also on your list, it is well worth exploring.
StimSure raises common questions around which areas it treats, how many sessions you need and how it feels. The answers below cover what patients most often ask before booking.
StimSure is an advanced electromagnetic muscle stimulation (EMS) treatment from Cynosure that strengthens, tones and sculpts muscle. At Dr Joney De Souza Clinic in Marylebone, it triggers strong, involuntary muscle contractions far beyond what you could achieve voluntarily, which builds and defines muscle in targeted areas. It is non-invasive and needs no downtime.
StimSure commonly treats the abdomen, buttocks, arms and thighs to improve tone, definition and core strength. It is a popular choice for soft, undefined upper arms, sometimes called bingo wings, where you want a firmer, tighter look. Your practitioner confirms the most suitable areas for your goals at consultation, and many patients combine areas across a course.
Most patients have a course of around six sessions for visible toning, scheduled a few days apart. The exact plan depends on your goals and starting point, which your practitioner confirms after assessing you. Results build across the course as the muscle responds, and maintenance sessions help sustain the definition.

Had my second session of PRP with micro needling today and I am so far very happy with my results. Dr De Souza is just the kindest man who really has the best intentions for you.
I highly recommend Dr. Joney and his clinic. I have been his patient for many years and he is definitely one of the best. His work is natural and subtle, he always puts the patient’s interest first and will never try to upsell unnecessary treatments.
Dr Joney is the most wonderful Dr, kind and caring and highly experienced. I feel safe in his care and trust his opinion 100%.
