A makeup brush is a tool used to apply cosmetics to the face and body. It typically features a handle and bristles made from synthetic or natural fibers. Different types of brushes are designed for specific applications, such as foundation, blush, eyeshadow, and eyeliner, allowing for precise and even makeup application. Makeup brushes come in various shapes and sizes, each serving a unique purpose. For example, a foundation brush is flat and dense, while a blush brush is fluffy and rounded. Proper care and cleaning of makeup brushes are essential to maintain their performance and hygiene.
