Dark Spot Skincare for the Marks That Overstay Their Welcome

The mark outlasts the blemish. Post-inflammatory pigment is the acne problem nobody budgets for. We shortlisted the best-tolerated brightening actives in the accessible tier, arbutin and tranexamic acid among them, plus Korea's bestselling dark-spot serum. The newest arrivals reach into the clinic tier: azelaic and kojic in one layer, and arbutin dosed inside a daily moisturizer. Everything on this page has a named pigment-targeting reason to be here: tranexamic acid, azelaic and kojic, alpha-arbutin, niacinamide dosed for tone, or vitamin C. Glow on its own is not one.

This shelf grows. We add entries as products clear the bar, never to fill space.
