New combo therapy for vitiligo shows promise in early trial

This study tests whether adding carboxytherapy (injecting carbon dioxide gas under the skin) to standard narrowband UVB light therapy can improve repigmentation in people with stable, non-segmental vitiligo. Fifty-nine adults with at least two matching patches on their body will receive whole-body light therapy plus carboxytherapy on one randomly chosen side. The main goal is to measure how much color returns and to check changes in certain skin markers. This is a Phase 4 trial, meaning the treatment is already approved for other uses and is being tested for this new purpose.
