How scoring works

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

As an Amazon Associate, Greenlens earns from qualifying purchases. Affiliate income never changes a rating or ranking.Privacy Terms
