I don't know why it took me so long to try eyeshadow primer since I religiously use face primer, but I didn't realize how much it could improve the look and staying power of my eyeshadow. This stuff really helps the colors show up, and they stay vibrant for so much longer than without primer. I can take a shower and still have a complete eyeshadow look on! And then it comes right off with a swipe of makeup remover. Love it.
