Here's how I use this product: After applying moisturizer, concealer, and powder foundation, I apply my blush to the apples of my cheeks only and blend. Then I suck in my cheeks and apply the darker color from the deepest part of the hollow under the apple to the earlobe. Blend THOROUGHLY. When people say, "Don't bother contouring your face, you're not fooling anyone," it's usually because the darker color (contour powder) is not blended enough, which makes one look as if one smeared a brushful of eyeshadow accidentally, or else as if one were making brownies in a hot kitchen. I usually use a dense, soft buki brush to make circular strokes that go up and out away from my nose. The result should be utterly seamless. Next, use an angled brush to apply the lighter color (highlighter) to the tops of the apples and up around the occipital bones and over the browbone, in a heart shape. Now blend, but one needn't be so neurotic about it as one was with the contour blending. To be honest, for day I also use the contour powder as my eyeshadow contour and the highlighter on my lids and browbone. It makes the eyes and lashes pop, yet looks natural. (And it keeps the touch-up bag light!) In brighter lighting conditions, apply with a light hand, for darker conditions go more heavily--as you would with any of your make-up.
