Further study details as provided by University of Miami:

Primary Outcome Measures:
  • Melasma Area and Severity Index (MASI) [ Time Frame: Day 0, Week 4, Week 8, Week 12 ]
    The following equation is used to determine the MASI score: MASI = .3A(D+H) [forhead] + .3A(D+H)[right malar] + .3A(D+H)[left malar] + .1A(D+H)[chin]; A = area, D = darkness, and H = homogeneity. Area is based on percentage of the region covered by melasma using a 1-6 scale. Darkness is determined on a 0-3 scale. Homogeneity is based on a 0-4 scale.

Secondary Outcome Measures:
  • Patient Assessment [ Time Frame: Week 4, Week 8, Week 12 ]
    Subject critiqued their melasma as either getting worse, showing no improvement, mild improvement or as showing marked improvement upon using the treatment.

  • Evaluation of Photographs [ Time Frame: Post-Week 12 ]
    Photos were evaluated using the grading of worse, no improvement, mild improvement or marked improvement comparing week 12 to baseline.

  • Adverse Events [ Time Frame: Week 4, Week 8, Week 12 ]
    Recorded any and all adverse events that occurred even if it was unlikely that it was associated with the study product.
