Our ratings are primarily from the CIR (The Expert Panel for Cosmetic Ingredient Safety) which is an independent panel of experts that assesses the safety of ingredients used in cosmetics and publishes their results in peer-reviewed literature.
The CIR is an independent, non-profit scientific body that was launched in 1976 with support of the U.S. Food & Drug Administration (FDA) and the Consumer Federation of America (CFA) to assess the safety of ingredients used in cosmetics in the U.S.
The CIR comprises of world-renowned scientists, including dermatologists, pathologists, toxicologists, and chemists. These experts are independent of the cosmetics industry and must adhere to a strict conflict of interest policy.
