Objective To assess the efficacy and safety of 308 nm excimer laser in the treatment of vitiligo in faces and necks. Methods Thirty-one patients with vitiligo in faces and necks （65 lesions）were investigated. The lesions of vitiligo were treated with 308 nm excimer laser two times per week. Efficacies were evaluated every 10 times, 20 times and 30 times. The clinical response to therapy and adverse effects were recorded. Results Totally 3! lesions were cured （47.7%） and the total effective rate was 89.2% ;duration of less than or equal to 1 years of treatnent showed a statistical difference 94. 3% （ 33/35 ） vs 76.7% （ 23/30 ） ] （X2 = 4. 21, P 〈 0. 05 ）. Conclusions The 308 nm excimer laser is safe and effective in treating vitiligo in faces and necks.
