In order to properly apply the Mineral finishing powder, you will need: Mineral Finishing Powder and a large powder brush. Once you have applied all of your other makeup (i.e. blush, foundation, eyeshadow, eyeliner, etc.), then you are ready for the finishing powder. Open your finishing powder. Dip your brush into the powder. Tap the brush, in order to remove the excess powder. Then, apply the powder to your face. Dust it all over your face. You may need to dip the brush in the powder a few times more, in order to dust your entire face. This will set your makeup and make your pores less visible.
