If you prefer to apply your powder with a brush, make sure you dip your brush into powder, tap off the excess, or press the brush into pressed powder and tap away the excess and use the brush to press the powder into your skin. Rubbing or dragging powder on your face will only take away your foundation, and leave your complexion looking patchy and textured. If you prefer to apply your foundation with a sponge, you can definitely apply your powder with a sponge - just keep in mind that you need to gently press your powder into your skin, and not drag or rub the powder on your face. More often than not, your makeup will look cakey if you apply too much powder, regardless of your skin type. How you apply powder can make or break your makeup look.
