I actually used this product in a free sample that I got when purchasing a naked palette. I use it every day with my naked shadow, and my eyeshadow stays on all day and doesn't crease. I purchased this product from ulta after trying the sample, I loved it so much! It is about $20/bottle, but I have tried other discount eyeshadow primers, and they don't compare to this one! It smooths on my eyelid so perfectly and even, I just have to rub it in with my finger, and little goes a long way! I only have to use a little on each application, so this tube lasted me for almost a year, and I wear eyeshadow every day!! I will continue to purchase this eye shadow primer, even if I use it with other brands of eyeshadows, it still works great. I would recommend this eye primer to anyone and am overall very satisfied with this product.
