Primary

MeasureTime frameDescription
Success rate of treatment according to RL*IBaseline, 1 week after final treatmentThe success rate is determined by the change rate (%) of the relative lightness measured before the treatment (day of screening) and 1 week after the final treatment.

Secondary

MeasureTime frame
Relative skin lightness using the colorimeter(RL*I)Baseline, 1 week, 4 weeks, and 12 weeks after the final treatment
mMASI (modified Melasma Area Severity Index) evaluationBaseline, 1 week, 4 weeks, 8 weeks, and 12 weeks after the final treatment
Subject satisfaction (5-point scale questionnaires on subject's satisfaction)1 week and 12 weeks after the final treatment
