- Success rate of treatment according to RL*I [ Time Frame: Baseline, 1 week after final treatment ]The 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.
- Relative skin lightness using the colorimeter(RL*I) [ Time Frame: Baseline, 1 week, 4 weeks, and 12 weeks after the final treatment ]
- mMASI (modified Melasma Area Severity Index) evaluation [ Time Frame: Baseline, 1 week, 4 weeks, 8 weeks, and 12 weeks after the final treatment ]
- Subject satisfaction (5-point scale questionnaires on subject's satisfaction) [ Time Frame: 1 week and 12 weeks after the final treatment ]
