A makeup brush is a tool with bristles, used for the application of makeup or face painting. The bristles may be made out of natural or synthetic materials, while the handle is usually made out of plastic or wood. When cosmetics are applied using the appropriate brush, they blend better onto the skin.

There is a large variety of shapes and sizes of makeup brushes, depending on the face area where makeup will be applied, the cosmetic product and the wanted result. For example, the shape of the brush tip can be chiseled, straight, angular, round, flat or tapered.
