Hyperpigmentation — dark spots, melasma, or marks left after breakouts — has many causes, and no serum erases it overnight. The most evidence-backed daily step is actually sunscreen, since UV makes most pigmentation worse. Beyond that, several ingredients are researched for the look of an uneven tone: niacinamide, for instance, has been studied for reducing the appearance of facial spots, though results are gradual and depend on continued use. Below are the serum types people consider, with honest notes. Patch test, and see a dermatologist for stubborn or spreading pigmentation.
