Pinc Stuff demonstrates how to make your own eyeshadow primer. An eyeshadow primer acts as a barrier between your skin and your eyeshadow. It helps prevent creasing and makes your eyeshadow look more vibrant and last longer. You will need a sample jar, a toothpick, a popsicle stick, liquid foundation or concealer and white body butter. To make the primer, squirt out one part of concealer into the jar with one part of body butter. Stir the mixture with a toothpick until it is well blended. Add shimmer for a sparkly look, if desired. Let the primer sit for a while on your skin before applying you eyeshadow on top of it.
