A buffing brush is a makeup tool designed to blend and smooth out foundation, powder, or other face products. It typically features densely packed bristles that help achieve an airbrushed finish by evenly distributing product across the skin. Buffing brushes can be used with both liquid and cream formulations, making them versatile for various makeup applications. These brushes come in different shapes and sizes, but they usually have a flat or slightly rounded head. Many makeup enthusiasts prefer using a buffing brush for its ability to create a seamless look, reducing the appearance of streaks or lines. Proper cleaning and maintenance of a buffing brush are essential for hygiene and longevity.
