I don't know about you, but I've been pretty frustrated with my eye shadow these days. I feel like I put it on in the morning and it gradually comes off during my day to day activies. I decided I needed to try Mary Kay's eye primer. I've used it a few times and I am in love with this product. Not only does it increase the staying power of your eye shadow, but it also creates a nice surface on your eyelid so your eye shadow doesn't smudge or crease. I highly recommend trying this product.
