Lipstick is a cosmetic substance for the lips that is heavier than lip gloss and has the primary purpose of applying color to the lips. Most lipsticks are red or reddish, which has the effect of simulating the appearance of sexual arousal, which naturally increases blood flow and reddens the lips in fair-skinned people, and hence making the wearer appear more sexually attractive, but with modern pigments lipstick is available in practically any colour or shade.

A typical lipstick contains many chemical ingredients, principally pigments, oils, waxes, and emollients. Perfume and/or flavoring may be added to cover the odors and tastes of the other ingredients.

As with most other types of makeup, lipstick is typically, but not exclusively, worn by women.
