For spot concealing: Apply concealer to any area you want extra coverage. Blend out using a dabbing motion to keep concealer concentrated in that area with a concealer brush or your finger.
For highlighting: Apply a shade 1-2 shades lighter than your foundation on the high points of your face such as the center of your forehead, bridge of the nose, tops of the cheekbones, and under your eyes to brighten. Blend out with a makeup sponge, or foundation brush keeping the product in the area you applied it.
For contouring: Apply a shade 1-2 shades darker than your foundation on the areas you want to recede or create shadows on. This can be on the perimeter of your forehead, sides of the nose, under your cheekbones, and along the jawline. Blend out with a makeup sponge or foundation brush, keeping the product in the area you applied it.
