Outcome Measures

Primary Outcomes (1)

  • Depigmentation

    Assessment of depigmentation: For each treated area, response will be assessed as follows (van Geel et al., 2015): * Digital clinical pictures will be used to evaluate the capacity to induce depigmentation and to assess the percentage of depigmentation per test area. * Treatment results will be subsequently classified according to a grading system from 0 to 6 (0 = no effect, 1 = \<25%; 2 = 25-49%; 3= 50-47%; 4= 50-74%; 5=90-99%; 6=100%), corresponding to the grade of depigmentation.
