Cosmetics, also known as make-up, are care substances used to enhance the appearance or odor of the human body. They are generally mixtures of chemical compounds, some being derived from natural sources (such as coconut oil) and some being synthetics.

In the U.S., the Food and Drug Administration (FDA), which regulates cosmetics, defines cosmetics as "intended to be applied to the human body for cleansing, beautifying, promoting attractiveness, or altering the appearance without affecting the body's structure or functions." This broad definition includes any material intended for use as a component of a cosmetic product. The FDA specifically excludes soap from this category.
