concern:sensitiveThe Word "Fragrance" Is Hiding 3,000+ Ingredients. Here's the Loophole.On a skincare label, the word “fragrance” — or its alias “parfum” — is a legal catch-all that can hide more than 3,000 undisclosed ingredients. U.S. and EU regulations let brands list every component of a scent under that one word, which means the compounds linked to hormone disruption, asthma, and skin sensitization rarely have to appear by name. The fastest way to find out what your products actually contain is to flip a bottle over and check the ninth ingredient.
