To go hand in hand with my homemade highlighting contour cream, I made this homemade dark contouring powder with these ingredients from my kitchen. Cinnamon causes blood to come to the surface and may cause tingling and/or redness. These experiences may be reduced with use of a carrier oil. Use with caution, but I personally did not experience any discomfort using it directly on my face, so test before using.
I added cinnamon, nutmeg, and cocoa to a small amount of cornstarch to get my desired shade of dark contouring powder. You can put this is a compact case with little oil, but I used it as a loose powder with a brush.
