Add the arrowroot flour or cornstarch to a bowl. (Cornstarch is more common, but may contain GMOs.)

Start with 1 tablespoon beetroot powder, then add more until you like the color. Equal parts beetroot and arrowroot will give a lighter blush, while a 2:1 beetroot-arrowroot ratio will give you a darker, more true pink. Experiment with mixing equal parts turmeric, beetroot, and arrowroot for a peach-colored blush, or add cocoa powder to darken the hue.

Mix the powders with a spoon to break up clumps, then transfer to a lidded jar and store in a dry place.

To use, just dip a brush into the powder, tap off the excess, and apply to the apples of your cheeks.
