Measurement-first evidence
A trained technician captured standardized facial images at Baseline and Weeks 2, 4, and 8. ImagePro software provided instrument-based measurement of four appearance endpoints.
76%of the hyperpigmentation subpanel improved at Week 8.
85%of the full panel moved favorably on the L* endpoint at Week 8.
How to read the results
Mean improvement describes the average measured change. “Participants improved” describes how many individuals moved in the favorable direction. Both are shown without blending them.
