TIP #1Use a primer on the lids. One of the most common & frustrating problems we face during the summertime is running makeup. If your eye shadow cracks, disappears or becomes oily in the heat, apply a layer of eye shadow primer to the lids to keep the eye shadow in place. Blend a small dot of primer on the lids and let it dry before you apply your eye shadow. You can find eye shadow primer anywhere you usually buy your makeup!
