Urban Decay's claim:
This miracle eyeshadow primer is unmatched by any other in the beauty industry! The genie in this bottle fulfills three wishes: eyeshadow that lasts, more vibrant and lasting color, and absolutely NO creasing.
It goes on quickly and easily although I recommend blotting it on with the wand and then smoothing it out with your finger. It dries quickly and does not affect the color of your eye shadow.
When I bought it I was highly skeptical of its ability to make my eye shadow last without creasing, but being the sucker that I am, I was grabbed by the marketing and bought it anyway. The first day I used it my expectations were low. I put my make-up on at around 7:30AM as I do most mornings and I was absolutely shocked to look in the mirror at around 5PM and see that I still had eye shadow on my eyes. No creases either. Amazing!
