- We cross-reference ingredient information with lists of prohibited ingredients from government and non-profit health and environmental groups.
- Due to the lack of formal government regulations, most of these lists are guidelines only, but they are backed by scientific studies with abstracts that are available to the public.
- We take the health impacts of cosmetics seriously, so if there’s enough evidence showing that even a single ingredient is unsafe, it will be listed as “Dirty” on the “Dirty Meter”.
- The ratings are strictly based on our own interpretation; other sources could have their own opinions. For more information, please tap the rating box on the Product screen, or you can also review our Terms of Service.
For a detailed overview, please review our Methodology section which will also give you a clearer picture!
