We are taking a break from hyperpigmentation actives! In this finale, we tie together months of research to help you build the ultimate hyperpigmentation skincare routine. We rank the actives from our last 10 episodes—including Hydroquinone, Azelaic acid, Arbutin, Glutathione, Thiamodol, Symwhite, etc. —from S-Tier (Gold Standard) to Tier “Meh.” We also filter through the 18 products we tested down to the ones we think should be on your radar and warn you about "Niacinamide Overload."
