Abstract:
Objective To observe the efficacy of Er ∶ YAG laser and pulsed dye laser (PDL) in treating facial acne scars.Methods A total of 78 cases with facial acne scars were divided into two groups.The test group included 40 patients that were treated by Er ∶ YAG laser (total three treatments,once three months)and irradiated by PDL (total four times,once per month),while the control group included 38 patients treated by Er ∶ YAG laser only.After three months of the last treatment,the effective rate and side effects were recorded and compared.Results The efficacy of the test group reached 92.5％ (37/40) and 77.5％ (31/40) for acne scars and post-acne erythema,respectively.However,the effective rate of the control group was 73.7％ (28/38) and 47.4％ (18/38).There were statistically significant differences between two groups (P＜0.05).Regarding reported adverse effects,there were four cases in the test group and two cases in the control group that appeared mild pigmentation.After symptomatic treatment,the skin color recovered.There was no other side effect in both two groups.Conclusions The effectiveness of Er ∶ YAG laser and PDL is better than Er ∶ YAG laser only in treating facial acne scars,and thus it is worthwhile for popularization and application in acne scars.
