The go to eyeshadow primer I use is Urban Decay's eyeshadow primer. Let me start out by saying, why I even chose to use Milani's eyeshadow primer. I wanted to find a dupe close to Urban Decay's. I love Urban Decay, but I do not like the wand/bottle its in, cant even get all the product out! Also, its on the medium expensive end. For somebody who wears makeup daily, its expensive to keep purchasing when there are other makeup places that have great dupes! I went to google some of the dupes and this was one of the top searches. I watched many youtuber's videos (not only Jeffree), and it seems promising. I have oily eyelids, oily meaning, eyeliner does not work on me unless I have eyeshadow. I tried this on since 10 am in the morning and its already 8pm! My eyeshadow did not budge and no fall out. I have to say, I am going to use this eyeshadow primer from now on. Its cheaper, easy to use and has a squeeze bottle (can get ALL product out). Thanks Milani!
