Laser zaps sweat glands in tiny hyperhidrosis trial
NCT ID NCT04178161
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early study tested a laser treatment for people with excessive sweating (hyperhidrosis). The approach used a dye to mark sweat glands, then a special laser to destroy them. Only 2 people were enrolled, and the study was terminated early, so we have very little data on whether it works or is safe.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Laser treatment (fractional erbium laser) combined with methylene blue iontophoresis
- What this could lead to
- If it works, this could point toward a minimally invasive treatment for excessive sweating without long-term medication.
- What could go wrong
- This was a very early, tiny trial (only 2 participants) that was terminated, so results are extremely limited. The procedure may not be effective or safe for broader use.
