114 carry a second notified active

Measured July 2026 · from ingredient lists we collected ourselves

Niacinamide is a notified brightening active under the MFDS, with a set range of 2 to 5 percent (Annex 4). The problem is how common it is. Four in every ten products we collected carry it, so presence alone tells you nothing. So we look at two things instead. First, whether it sits high enough on the label to match that range. Second, whether another active from the Annex 4 list joins it.

We checked all 894 products in our database that contain niacinamide. 114 of them also carry another notified brightening active from Annex 4.
