Stimsure is a state-of-the-art, non-invasive muscle building and toning technology from Cynosure.
StimSure is an advanced electromagnetic muscle stimulation (EMS) treatment designed to strengthen, tone and visibly sculpt the body. Using targeted EMS technology, StimSure contracts the muscles far more intensely than is possible through voluntary exercise. Each session lasts around 20–30 minutes and can treat multiple areas such as the abdomen, glutes, thighs and arms in a single appointment. Clinical studies show significant improvements in muscle density, definition and strength after a short course of treatments.


StimSure is ideal for anyone wanting to enhance muscle tone, improve core strength or achieve a more defined physique without surgery or downtime. The treatment delivers a series of controlled electromagnetic pulses that cause deep, sustained muscle contractions, helping build and firm the muscles over time. These contractions activate both fast-twitch and slow-twitch fibres, making StimSure a powerful complement to regular exercise or an effective solution for those struggling to target specific areas through workouts alone. With each session, the muscles become stronger, more sculpted and noticeably more defined, creating a natural, athletic look.


Dr Joney De Souza Skin and Laser Clinic is one of the few clinics in London offering StimSure, a next-generation EMS treatment designed to strengthen, tone and sculpt the muscles without surgery or downtime. StimSure uses powerful electromagnetic pulses to trigger deep, sustained muscle contractions that go far beyond what can be achieved through regular exercise. This advanced technology allows precise targeting of areas such as the abdomen, glutes, thighs and arms, helping to build muscle definition, improve firmness and enhance overall body shape safely and effectively.
StimSure is an advanced EMS (electromagnetic muscle stimulation) treatment that triggers strong, involuntary muscle contractions. These contractions help build, tone and strengthen muscles in areas such as the abdomen, glutes, thighs and arms.
Most patients see the best results after a course of 6–8 sessions, usually performed twice a week. Dr Joney will tailor your treatment plan based on your goals and target areas.
StimSure is not a weight-loss treatment. It tones and strengthens muscles, enhances definition and improves firmness. It works best alongside a healthy diet and lifestyle.
StimSure is generally comfortable. You will feel strong contractions as the machine activates the muscles, but most patients find this very tolerable. Intensity can be adjusted to your comfort level.
No. StimSure is completely non-invasive and has no downtime. You may feel mild muscle fatigue similar to a workout, but you can return to your usual activities immediately.
