Why can't brands list exactly what's in fragrance?

Fragrance is a complex blend of dozens of components, and cosmetic regulations allow brands to list it as a single ingredient to protect proprietary formulas. This protects business interests but makes it impossible for consumers to identify which scent components might trigger an allergic reaction.

Can fragrance cause allergies?

Yes, fragrance is the single most common cause of cosmetic contact allergy. The undisclosed blend means you cannot see what components are present, so if you react, you cannot easily identify the specific culprit. People with known fragrance sensitivities should choose fragrance-free products.

Is fragrance safe if I don't have allergies?

For people without a known fragrance sensitivity, fragrance in rinse-off products (shampoos, body washes) carries low risk because the product washes away quickly. Leave-on products like moisturizers carry a higher risk if you have reactive skin, so patch-testing before use is advisable.
