About this data
This page summarizes adverse event reports from the FDA's adverse event reporting system for cosmetic products. Reactions are coded in MedDRA. Reports come from consumers, health professionals, and industry. The presence of a report does not establish that the product caused the event - it only reflects what was reported to FDA.
Limitations: The public dataset does not include free-text case narratives, only structured fields.
