The eyes have it..but not when your shadow starts to crease or run off your eyelid. Its hard to put on makeup only to be defeated by sun and humidity- but, I have found 2 products that help cease creases! The first is the coveted Urban Decay Primer potion. The wand makes for easy application and it can be used under your foundation. Its tried and true. The second is a personal favorite- Nars Concealor, I know that its not the conventional "primer" but it does the job. I prep my lids with a little and shadow looks as great 6+ hours later than when I initially put it on.
