About these ratings
Every number is a published rabbit-ear assay grade (Fulton 1989 lineage), shown with its source and a confidence tier on the ingredient page. A rating describes a raw ingredient as tested, not a finished product: concentration, formulation and individual skin decide real-world behaviour. 3/5 and up is where the 1989 AAD symposium recommended caution.
