A fan brush is a type of paintbrush that has bristles arranged in a fan shape. This unique design allows artists to create various textures and effects, making it a popular choice for painting and makeup. The fan brush is especially useful for blending colors, adding highlights, or creating delicate details in artwork. In addition to painting, fan brushes are often used in makeup application. They can help apply highlighter to the cheekbones or blend eyeshadow for a softer look. Their versatility makes them a favorite tool among both artists and beauty enthusiasts alike.
