About

A widely used UV-B sunscreen filter (up to 10% in the EU). Effective and stabilizes other filters, but degrades to benzophenone over time — a recognized concern that drops it to yellow.

Skin benefits

  • EU-approved UV-B and short UV-A filter (up to 10%)
  • Stabilizes photo-unstable filters like avobenzone
  • Established efficacy and broad sunscreen use

Known concerns

  • Degrades over time into benzophenone — a probable endocrine disruptor and potential carcinogen
  • Reported cases of contact and photo-contact allergy
  • Marine-environment concerns (coral reef impact)
  • SCCS has flagged the benzophenone breakdown as a safety priority
