To determine the effectiveness of combining laser therapy with an immunosuppressive approach, the investigators recruited 14 subjects, aged 12 to 63 years, with Fitzpatrick skin types II to IV and having had vitiligo for a minimum of three months. A total of 43 vitiliginous lesions were randomized to receive either 308-nm excimer laser monotherapy twice weekly for six weeks or the laser sessions plus topical 0.1% tacrolimus ointment applied twice daily. Treated lesions were matched with untreated lesions on the subjects' opposite side.
