ABOUT THE SKIN DEEP® RATINGS
EWG provides information on personal care product ingredients from the published scientific literature, to supplement incomplete data available from companies and the government. The ratings below indicate the relative level of concern posed by exposure to the ingredients in this product - not the product itself - compared to other product formulations. The ratings reflect potential health hazards but do not account for the level of exposure or individual susceptibility, factors which determine actual health risks, if any.

ABOUT EWG VERIFIED™
Beyond providing Skin Deep® as an educational tool for consumers, EWG offers its EWG VERIFIED™ mark as a quick and easily identifiable way of conveying personal care products that meet EWG's strict health criteria. Before a company can use EWG VERIFIED™ on such products, the company must show that it fully discloses the products' ingredients on their labels or packaging, they do not contain EWG ingredients of concern, and are made with good manufacturing practices, among other criteria. Note that EWG receives licensing fees from all EWG VERIFIED™ member companies that help to support the important work we do. Learn more | Legal Disclaimer
