Niacinamide is a brightening active the MFDS recognises, at 2 to 5 percent. The problem is how common it is. Four in every ten products we collected carry it, so presence alone tells you nothing. We look at two things instead: whether it sits high enough on the label to match that dose, and whether a second recognised brightening active joins it.
We checked all 1059 products in our database that contain niacinamide. 129 of them also carry another recognised brightening active the MFDS recognises.
"high for its class" = the top 20% among the 1059 products we have that contain niacinamide.
From the 41 that clear every check, we kept 10 and spread them across formats so there is something to choose from. Nothing here is a claim about results.

The other 930 products carry niacinamide on its own. That still counts as a recognised brightening active, so it is not a flaw. This list simply collects the formulas that go one step further.
Prices and stock are set by each seller. Positions on this page come from ingredient lists we collected and are not a measurement of concentration.
