Summary
This study tested a device called Evolve that uses electromagnetic stimulation and radiofrequency energy to reduce belly size and tighten skin without surgery. Twenty adults received treatments and were followed for 6 months. The main goal was to see if waist circumference decreased and if skin appearance improved.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Evolve System (device delivering combined electromagnetic stimulation and radiofrequency)
- What this could lead to
- If it works, this could offer a non-surgical option for reducing belly size and tightening skin.
- What could go wrong
- This is a very small study (20 people) with no control group, so results may not apply to everyone. Effects may vary and long-term safety is not established.
