Which agency is responsible for regulating cosmetics in the United States?

The Food and Drug Administration (FDA) is the agency responsible for regulating cosmetics in the United States. The FDA oversees the safety of cosmetic products and their ingredients, ensuring that they do not pose a risk to consumers when used as intended. This includes monitoring the labeling of cosmetics to guarantee that they provide accurate information and do not make false claims regarding their effectiveness or safety.

The FDA's role also extends to conducting research and providing guidance on cosmetic safety and labeling practices. While other agencies, such as the Environmental Protection Agency, focus on broader environmental health issues, and the Centers for Disease Control and Prevention address public health concerns, the FDA specifically handles regulations related to the cosmetics industry, providing a regulatory framework that manufacturers must comply with to ensure consumer safety.

Additionally, the Federal Trade Commission deals primarily with advertising practices and competition, but it does not regulate the safety of cosmetics. Thus, the FDA is the appropriate regulatory body when it comes to cosmetic products in the U.S.
