Primary Outcome Measures

Name	Time	Method
Global assessment of acne scar	12 weeks	5-point grading of acne scar quartile assessment of acne scar improvement through comparing the photos taken before treatment and after treatment

Secondary Outcome Measures

Name	Time	Method
ECCA	12 weeks	quantitative assessment of acne scar ECCA assessment is established by previous article. this method quantifies severity of acne scar by counting the number of acne scar categorized by their shape. Then, the number of scars are multiplied by weighing factors determined by scar types. ECCA is the total sum of these points. please refer the Dreno et al, Dermatology, 2007;214:46-51
Adverse effect	12 weeks	adverse effects were measured by Epithelization Scale. ES is the total sum of evaluation of three components after wounding. please refer this article Min et al, Wound Repair and Regen, 2014;22(2):212-9
