A cosmetic product information file (PIF) is the dossier the Responsible Person must keep for every product placed on the EU market under Article 11 of Regulation (EC) 1223/2009: a product description, the cosmetic product safety report, the manufacturing method and GMP statement, proof of the effects claimed, and data on any animal testing. It must be available to authorities at the Responsible Person’s address for ten years after the last batch is placed on the market.
Claims are governed by Article 20 and the common criteria in Regulation (EU) 655/2013: legal compliance, truthfulness, evidential support, honesty, fairness and informed decision-making. A claim that the evidence does not support is non-compliant wherever it appears, including product pages, social posts and influencer briefs. The UK applies equivalent rules through its own cosmetics regulation.
The hard part is not knowing the rules. It is that claims are written in dozens of places by people who never see the PIF, and the evidence sits in lab reports and supplier dossiers that nobody has linked to the wording.
