Do all cosmetic manufacturers include ingredient labels on their products?

Yes. Proper labeling is an important aspect of marketing a cosmetic or personal care product. Labeling is used to help inform consumers of a product's intended use and any related warnings, its ingredients and net quantity of contents, and its place of manufacture or distribution. The U.S. Food and Drug Administration (FDA) regulates cosmetic labeling under the authority of both the Food, Drug, and Cosmetic Act (FD&C Act) and the Fair Packaging and Labeling Act (FPLA) .
