Six months is the longest published follow-up for EMsculpt NEO, and the result held at six months in the one sham-controlled trial. Beyond that the honest answer is the clinic's experience, not a study: the muscle fades like any training if you stop using it, and the fat holds while your weight holds. In our practice a single maintenance session every three to six months keeps the tone, decided together at your free three-month review. Sessions are at Chelsea Clinic, 8 Exhibition Road.
What the studies measured, and for how long
- The sham-controlled trial, 72 patients, three weekly abdominal sessions (2022): fat 28% thinner and the abdominal muscle 24% thicker on ultrasound at three months, and "improvements were maintained at 6 months". The sham group showed no significant change. The authors advise the manufacturer.
- The US clearance study for the abdomen, 42 patients: fat 30% thinner and the waist 3.2 centimetres smaller at three months, with 88% losing 1.5 centimetres or more. No later point.
- Flanks and upper arms (2023, 2024): fat 25 to 29% thinner and the muscle 24 to 27% thicker at three months on MRI. No later point.
- An independent review of 15 studies, 11 on the original EMsculpt and 2 on NEO (2024): abdominal fat about 5.5 millimetres thinner and muscle 2 millimetres thicker on average, no complications, and "two studies report marginal or no benefit".
So the published record stops at six months. Beyond that point, what follows is our experience.
Why the two halves of the result age differently
In our experience the muscle half behaves like exercise. The HIFEM contractions feel like a very hard workout, and muscle that is not used loses what it gained, so a person who trains keeps the muscle result longer than one who does not. The fat half is different: in our experience it holds while your weight holds, and gaining weight undoes it. That is why the guide asks you to keep your weight stable through the three months the result takes to show, and why the is it worth it page says it changes shape, not weight.
The timeline
- Two to four weeks after the last session: the first change, in our experience.
- Three months: the main result, when the studies measured and when we photograph and measure you at a free review.
- Six months: held, in the trial.
- After that: training keeps the muscle; weight keeps the fat result; a maintenance session every three to six months keeps the tone, in our experience. No published schedule exists.
What shortens it
Stopping training, gaining weight, and expecting a course to replace both. In our experience EMsculpt NEO works best in people near their target weight, with a body mass index under about 30, who train; the trials did not change body weight. The sessions page explains why the clinic's course is four sessions where the trial used three, and the difference page covers the original muscle-only device. EMsculpt NEO is FDA-cleared in the US.
