A shop's product page with the Formulary panel beside it. The panel counts 10 beneficial, 3 harmful and 3 neutral ingredients, and lists Glycerin and Niacinamide as Best, with strong evidence.

What you get

A quick look

How many of a product’s ingredients are beneficial, neutral or harmful, before you read a single name.

The reason, in plain words

Open any ingredient to see why it got its rating, and the studies or EU rules behind it.

Who stands behind it

Every rating says whether a person reviewed it, it comes from EU law, or it’s an estimate no one has checked yet.

Six ratings, one set of rules

Ratings come from published research and EU safety rules, run through the same fixed rules for every ingredient. Safety concerns are checked before benefits.
