The BLF 220 round kabuki brush is commonly used for applying foundation and buffing/blending it into the skin for a smooth and flawless finish. To use the brush, you can dip the bristles into your liquid or cream foundation, then buff and blend the product onto your skin in circular motions, starting from the center of your face and working outward.

The dense bristles of the kabuki brush allow for a more even application of foundation, and the circular motions help to distribute the product evenly and blend it seamlessly into your skin. You can also use the brush to apply other liquid or cream products such as concealer or cream blush.

It's important to clean your makeup brushes regularly to prevent bacteria buildup and to ensure that they perform optimally. You can clean your kabuki brush by washing it with mild soap and water or using a specialized brush cleanser. Allow the brush to air dry completely before using it again.
