NARS Pro-Prime Smudge Proof Eyeshadow Base
This NARS Smudge Proof Eyeshadow Base is by far the best I have tried. It is very lightweight, goes on white but dries quickly and sheer and absorbs any oil you might have on your lids. Bonus - no fragrance! It last ALL day and my shadow (both creams and powders) does NOT budge. It's a little expensive - for a .26 oz tube (with a doe foot applicator) it runs $24.
Now that I think about it, I might test drive this on NARS Cream Eye Shadows, which crease horribly on me, no matter what primer I use. This could be the ultimate test for me. If it doesn't crease with their own cream shadows, it will stay my HG!
