Using a 308-nm excimer laser to treat vitiligo in Asians.

Background: Current vitiligo therapies require many months of treatment and often result in disappointing outcomes. Treatment with a 308-nm excimer laser has shown promising results in patients with vitiligo.

Objective: This controlled prospective trial studied the effectiveness of the 308-nm excimer laser for treating vitiligo in Asians.
