Abstract：Objective:To evaluate the efficacy of intense pulsed light ( IPL)420 nm filter com-bined with 560/590 nm filter in treating inflammatory acne and acne erythema.Methods:A total of 44 cases of acne were recruited for the study and randomly divided into two groups.The treat-ment group (22 cases) were treated with IPL 420 nm combining with 560 nm/590 nm, while the control group (22 cases) only treated with IPL 420 nm,the clinical efficacy and patient′s satisfac-tion were analyzed.Results:The effective rate of two groups in inflammatory lesions was 81.8%and 77.3%, respectively.The difference has no statistically significance(χ2 =0,P<0.01) .The effective rate of acne erythema in the treatment group (86.3%) was significantly higher than that in the control group (54.5%,χ2 =3.93, P=0.047).1-month follow-up after treatment, the o-verall satisfaction rate of the treatment group and control group were 90.9%, 63.6%, respective-ly.The difference between two groups was statistically significant (χ2 =4.66, P<0.05).There was no serious adverse reaction investigated during the treatment.Conclusion:The therapy of in-tense pulsed light 420 nm combined with 560/590 nm has showed remarkable effect on inflamma-tory acne and acne erythema.
