Overall scar improvement was assessed by photographs taken at baseline and 3\u00a0months after the last treatment according to the 4\u2010point global assessment scale (GAS) and ECCA grading scale. Improvements in color, distortion, and texture were assessed by the modified Manchester Scar Scale and scored individually from 1 to 4.

The average score for overall improvement was 3.48. The average scores for color, distortion, and texture were 3.07\u00a0\u00b1\u00a00.62, 3.27\u00a0\u00b1\u00a00.50, and 3.52\u00a0\u00b1\u00a00.51, respectively. Mean pain degree score was 4.27\u00a0\u00b1\u00a01.04, and mean erythema duration was 28.43\u00a0\u00b1\u00a06.58\u00a0days.
