Mean percent change from baseline of dark spot intensity, contrast, and size in the overall group (A), PIH subgroup (B), and solar lentigines subgroup (C). Overall group: n = 40 at Weeks 2 and 4; n = 41 at Weeks 8 and 12. PIH subgroup: n = 22 at Weeks 2, 8, and 12; n = 21 at Week 4. Solar lentigines subgroup: n = 18 at Week 2; n = 19 at Weeks 4, 8, and 12. *p ≤ 0.008, p ≤ 0.031, p ≤ 0.016 vs baseline (Wilcoxon signed-rank test).
