The best way to use a kabuki brush is to start with your fingers. Apply the foundation to your face in dots with your hands, or use a regular foundation brush to do this step. Then blend outwards, again with your hands or a standard brush, till you get a decently even face. The reason for starting this way is because the dense bristles of the kabuki brush will soak up the foundation and become very hard to clean. If you get the makeup settled onto your skin a bit first, it becomes much easier. Now that your foundation is all over your face, you can use the kabuki brush to polish the foundation into a flawless finish. Blend with small, rounded motions. It’s best to use the brush very lightly – the goal is to get a very even, smooth finish; not to push the makeup into your skin. You can also use the brush to set powder in the same way, using small rounded motions.
