Abstract: Objective To evaluate the efficacy and safety of 650 nm,810 nm diode laser on the treatment of moderate to severe acne.Methods A total of 87 patients with moderate to severe acne were divided into diode laser group (group A) and medication group (group B).In group A,the patients were irradiated with 650,810 nm diode laser at the fluence of 400-450 mW distance of 2-3 cm.In group B,the patients were treated with roxithromycin combined with vitamin B6 and gel lincomycini.Clinical follow-up was performed every week for 4 months.All the adverse effects were recorded.Results There was no significantly statistical difference in the cure rate between the two groups (group A versus group B at 2 weeks:65.0 ％ versus 42.6 ％,P＞0.05; at 4 weeks:92.5 ％ versus 76.5 ％,P＞0.05).However,the recurrence rate of group A was much lower than that of group B (30.0 ％ versus 61.7 ％,P＜0.01).There were no severe adverse effects in both groups during the period of the follow-up.Conclusions Compared to the medication,650,810 nm diode laser appears to be associated with lower recurrence rate in the treatment of moderate to severe acne.
