Objective： To observe the efficacy of red light treatment on moderate acne. Methods： A total of 70 patients with moderate facial acne were randomly divided into 2 groups,the treatment group（ 35cases） and the control group（ 35cases）. Patients in the treatment group received red light [（ 630 ± 10） nm] irradiation after cleaning the face,20 minutes each time,2 times a week,for 4 weeks. Patients in the control group were treated with Tretinoin Cream,Benzoyl Peroxide Gelcontinuous everyday for 4 weeks,the efficacy was compared between the two groups after 4 weeks. Results： After treatment,the number of inflammatory lesions（ papules and pustules）in the treatment group was significantly reduced compared with that in the control group（ P 0. 05）,but there was no difference between the treatment group and the control group（ P 0. 05）. Conclusion： Red light irradiation in the treatment of moderate facial acne is significant,especially for the inflammatory lesions,and also has fewer adverse reaction.
