How do we score?

When you scan a barcode we first look the product up in our own database. If it is not found, we read the ingredients from a label photo. The photo is processed on your phone; it is never uploaded or stored.

Every ingredient is assessed against open sources: CosIng (the EU's official cosmetic ingredient database), the EU cosmetic allergen list, and published comedogenicity ratings. Every ingredient is also checked against the FULL prohibited list of the EU Cosmetics Regulation (Annex II, 2,600+ substances). We never say "the AI said so"; every rating has a source.

First a general rating that applies to everyone, then a personal layer based on your skin type and concerns (acne, redness, fragrance allergy): for example, fragrance is "caution" for everyone but becomes "risky" if you have a fragrance allergy.

We start from 100 points: each ingredient risky for your profile subtracts 20, each caution ingredient subtracts 7. Sub-components of the same fragrance are counted as a group, not punished one by one.

Sources and freshness

Cosmetic ratings draw on CosIng (the EU's official ingredient list), the EU cosmetic allergen list, published comedogenicity ratings and the EU Annex II prohibited list; food ratings draw on EU additive regulation and EFSA/IARC assessments. We review the dictionary regularly and add ingredients as unrecognized ones come up. Last reviewed: 2026-07-11.

Privacy

The label photo you take to read ingredients is processed on your device and never stored. What we keep: the scanned barcode + ingredients text (for the community database), your own scan history if you signed in, and a product photo if you deliberately share one via 'Add a photo' (shown on the product after review).
