Lipstick is a cosmetic product used to apply coloration and texture to lips, often made of wax and oil. Different pigments are used to produce color, and minerals such as silica may be used to provide texture. The use of lipstick dates back to early civilizations such as Sumer and the Indus Valley Civilisation, and was popularized in the Western world in the 16th century. Some lipsticks contain traces of toxic materials, such as lead and PFAS, which prompted health concerns and regulation.

Lipstick has been prominent in several women's fashion trends, often associated with women's sexuality. The color of lipstick has aesthetic and cultural significance as different colors carry different connotations. Red lipstick has historically been associated with sensuality or women's independence while black lipstick is worn by both men and women in alternative subcultures, especially punk and goth. Celebrities such as Elizabeth Taylor, Madonna, and Taylor Swift have contributed to the popularity and iconic images of lipstick in fashion and media.
