Take your concealer brush(Compare Prices) and very gently mix the foundation in the lid by using a swirling motion. You will notice there is a significant amount of mineral powder on the brush. Do not automatically apply the minerals to your face, instead gently tap the excess from the concealer brush first.
Use the concealer brush on the areas where you need a little extra coverage. Apply the mineral foundation under and around your eye area, on blemishes and dark spots, and around the base of your nose area (where your nostrils are). Use smooth and even strokes when using the concealer brush, so you get a more even finish.
