What the FDA Actually Requires to Approve a Sunscreen Filter
Why 'it's safe in Europe' isn't enough for US approval.
The EU permits 34 UV filters; the U.S. allows only 16 (EWG).
EWG states the EU has approved 34 UV filters for sunscreens compared with 16 in the U.S.
Frequently asked questions
Is it safe to buy sunscreen overseas?
Buying reputable sunscreen abroad is generally fine, but check the expiration date, store it away from heat, and note that US import rules treat sunscreen as a drug. Counterfeit or heat-damaged products can lose effectiveness, so purchase from trusted retailers.
Why are European and Asian sunscreens different from American ones?
The US regulates sunscreens as OTC drugs, so adding a filter requires drug-level safety data and FDA approval — a slow process that stalled for decades. The EU, Japan and Korea treat them as cosmetics or quasi-drugs and approve modern filters faster, which is why foreign formulas often feel lighter and cover more of the UVA range.
Why can't I buy some foreign sunscreens in the US?
Sunscreens sold in the US may use only FDA-approved filters and must meet OTC-drug rules, so a foreign product containing filters the FDA hasn't cleared (e.g., Tinosorb M or Uvinul filters) can't be legally marketed as sunscreen here. You may see them sold abroad or, unreliably, via personal import.
