LED light tested for faster skin healing in tiny study
NCT ID NCT02677194
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether shining different colors of LED light (630nm, 830nm, and 590nm) on skin could speed up healing after a laser made small wounds. Ten healthy volunteers had tiny areas on their forearms treated with a fractional CO2 laser, then exposed to LED or no light. Researchers measured skin color and water loss to see if LED helped. The goal was to find the best LED settings for future use.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- LED light (630nm, 830nm, 590nm)
- What this could lead to
- If successful, this could point toward using specific LED colors to speed up skin healing after procedures like laser resurfacing.
- What could go wrong
- This is a very small, early study on only 10 healthy people, not patients with wounds. Results may not apply to real injuries or larger groups.
