Abstract: Objective To evaluate the clinical efficacy of the non-ablative 1550 nm fractional laser on post-acne atrophic scarring and post-acne erythema.By following up,the correlative factors were analyzed to guide the further use of the non-ablative 1550 nm fractional laser.Methods Twentyseven patients who received the non-ablative 1550 nm fractional laser therapy from Dec.2011 to June 2013 were enrolled in this retrospective study.We used a quartile grading scale for evaluation of postacne atrophic scarring and post-acne erythema.Results The effective rate was 13.0％ (3/23) for post-acne atrophic scarring and 44.0％ (11/25) for post-acne erythema.Nonparametric test showed that there was no statistical correlation of the efficacy with gender,age and courses of disease.But there was positive correlation between efficacy and treatment frequencies on post-acne erythema (r=0.619,P＜0.05).No severe adverse effect was observed.Conclusions We suggest that the nonablative 1550 nm fractional laser may provide a new treatment algorithm in some cases of post-acne atrophic scar and post-acne erythema.
