The purpose of blush is to add natural color to the face.
Locate cheekbones with finger. Using a Blush Brush start at the hairline and just beneath cheekbone. Blend blush down towards nose to the middle of the eye using back and forth strokes.
Using a Contour Brush blend blush line by dipping the brush into a little powder and blending the edges of the blush line. Do not cover top of cheekbone or go below the hollows of the cheek.
Wedge sponges can also be used for overall blending.
