A spot size of 10 mm was used, the average energy density was 14 J/ cm2. The improvement rate was obtained by physician and patient together. Furthermore, the physician assessment scores of improve- ment were also determined by side-by-side comparison of preoperative and postoperative photographs through B. Dreno ECCA grading scale. Results Acne scars were significantly improved by both physician and patient assessment. The average efficiency rate was 60%, im- provement rate was 40%, and the satisfactory rate was 100%.
