Mexoryl SX (Ecamsule)
INCI: terephthalylidene dicamphor sulfonic acid
Mexoryl SX (terephthalylidene dicamphor sulfonic acid, ecamsule) was L’Oréal’s landmark UVA filter — the first photostable short-UVA absorber with proven anti-photoageing credentials. Clinical research on Mexoryl-based sunscreens demonstrated reduced solar elastosis, pigment spots, and UV-induced skin changes over years of use. It is water-soluble, photostable, and FDA-approved (a rarity for EU filters) in specific Anthelios products. Its coverage focuses on UVA-II and short UVA-I (up to ~390 nm), so it is combined with other filters for complete spectra. A veteran filter whose clinical legacy still underpins dermatologist sunscreen recommendations.
