France has adopted a bill restricting the use of per- and polyfluoroalkyl substances (PFAS) in cosmetics. The legislation will take effect in 2026, prohibiting the manufacture, import, and sale of products containing PFAS in the country. PFAS are used in cosmetics to smooth the skin and hair or influence product consistency and texture. But mounting evidence has shown their connection to thyroid dysfunction, decreased immune response, and increased cholesterol levels. Some studies suggest an association between PFAS and kidney and testicular cancers.
