Melasyl (proprietary CeraVe/L'Oréal patent)
Neutral in 1
Scout's take
L'Oréal's patented dark-spot ingredient (2-mercaptonicotinoyl glycine). Limited independent peer-reviewed data — efficacy claims rely on company-funded studies. Not a known irritant, but novelty + sparse external evidence keep it neutral.
