Lamp vs laser: which light works best for vitiligo?
NCT ID NCT00696358
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared two types of ultraviolet light treatments—an excimer lamp and an excimer laser—for repigmenting white patches caused by vitiligo. Adults with at least two matching patches of vitiligo received both treatments on different patches twice a week for 12 weeks. The goal was to see which device produces better color return, and to check how safe and tolerable each is.
