The one rule

We never blend a score that hides who disagrees. Funding model travels with every rating. Weights are computed at read time and never stored.

Cosmetics only · lead with safetyProduct data from public sources incl. Open Beauty Facts & EWG Skin Deep · their ratings never scraped or shown

    Coverage & match quality

    8 ratings · 2 of 4 axes

    • Some ratings rest on an automatic match that has not been human-reviewed.
    • Fewer raters reach smaller-brand products, so a missing rating is not a clean bill of health, only a gap.
