I love a good, dramatic eye shadow; but am constantly annoyed by shades that smudge, smear, and lose their intensity. Put a Lid on It keeps even the most saturated hues on my lids and shining to their full potential all day. Just a tiny bit of this product on each lid does the trick. Do make sure to give it a full minute to dry before applying shadow, per the package instructions, for the full benefits. A great compliment to any shadow you use!
