What type of brush is best for blending foundation?

A stippling brush is best for blending foundation because of its unique design, which features duo-fiber bristles that can create a soft, airbrushed finish. The combination of long and short bristles enables the brush to pick up and disperse foundation evenly across the skin. This results in a seamless blend that minimizes streaks and provides a natural look.

In contrast, a flat foundation brush tends to leave visible strokes on the skin, making it less effective for achieving a flawless blend. A contour brush is specifically designed for applying and blending contour products, not foundation, and thus does not perform as well for this particular task. Lastly, a round blush brush is tailored for applying blush and may not have the appropriate density or bristle arrangement for fluid products like foundation, which can hinder blending performance.

Overall, the stippling brush is specifically designed for blending and offers the best results when working with various foundation formulas, enhancing coverage while maintaining a light, natural appearance.
