Contour brushes are specialized makeup tools designed to apply and blend contour products, which help define and enhance facial features. These brushes typically have angled or tapered bristles, allowing for precise application along the cheekbones, jawline, and nose. They can be used with cream, liquid, or powder contour products. Using a contour brush can create a more sculpted appearance by adding shadows and highlights to the face. Many makeup enthusiasts prefer contour brushes for their ability to achieve a seamless finish, making them a popular choice in the beauty community, alongside other tools like foundation brushes and blending sponges.
