Product's animal testing policies
Some cosmetics companies have taken People for the Ethical Treatment of Animals and Leaping Bunny animal-testing pledges. For consumers who are concerned about companies’ policies on animal testing, Skin Deep reports this information.
PETA Cruelty-free Companies

Companies that join the "Caring Consumer" program of People for the Ethical Treatment of Animals, a leading international animal rights advocacy organization, attest that "neither they nor their ingredient suppliers conduct or commission any animal tests on ingredients, formulations or finished products, and that they pledge not to do so in the future."

Products bearing the Leaping Bunny mark are certified cruelty-free under the Humane Household Products Standard, managed in the U.S. and Canada by the Coalition for Consumer Information on Cosmetics, a coalition of eight national animal protection groups. Participating companies must open their processes to independent audits throughout the supply chain.
LEARN MORE ON LEAPINGBUNNY.ORGUnderstanding scores
Cosmetics and personal care products are not required to be tested for safety before being allowed on the market. The Skin Deep® scoring system was designed to help the public understand whether a product is safe to use or whether it contains ingredients of concern.
Every product and ingredient in Skin Deep gets a two-part score – one for hazard and one for data availability. The safest products score well by both measures, with a low hazard rating and a fair or better data availability rating.
HOW WE DETERMINE SCORESHazard score
The Skin Deep ingredient hazard score, from 1 to 10, reflects known and suspected hazards linked to the ingredients. The EWG VERIFIED™ mark means a product meets EWG’s strictest criteria for transparency and health.
Data availability
The Skin Deep data availability rating reflects the number of scientific studies about the product or ingredient in the published scientific literature.
