Outcome Measures
Primary Outcome Measures
- Melasma Area Severity Assessment (MASI) Score Change From Baseline to Follow Up [3 Months]
The severity of the melasma is assessed based on a photographic scale. The scale ranges from 0 to 48, with 48 being the most severe. A decrease in the MASI score from the baseline to the follow up corresponds with decreasing severity.
