There are two main types of brushes that can be used for setting powder - a large, fluffy powder brush, or a small, dense brush. A large, fluffy powder brush will pick up a good amount of powder and distribute it evenly on the skin. This is a good option if you want to set your entire face with powder, or if you're using a loose powder. A small, dense brush will pick up less powder, but will give you more control over where the powder is applied. This is a good option if you want to target specific areas, like under the eyes or around the nose. No matter which type of brush you use, be sure to tap off any excess powder before applying it to your face. You don't want to end up with a cakey or powdery finish!
