The Kabuki brush is great with its soft, compact and synthetic hair. This brush is optimal for the application of mineral powders and all mineral-based makeup products. It is designed to crush the minerals beautifully and naturally into the skin. You can build your product up to a high coverage capacity by applying the product with the brush over and over again. You can also use the brush to fix or frost your concealer and/or foundation by tilting the brush with the product on to your skin.A good trick for using the brush for mineral powder is to put the kabuki brush down on the powder, move it calmly back and forth so you reduce powder dust, and get more out of your product.
