I stumbled across this eye makeup gem while perusing how-to makeup YouTube videos. No matter who I was watching, from young girls to seasoned pros, nearly everyone seemed to be using this shadow primer, so I had to try it. I did, and I haven’t stopped using it since. It sounds dramatic to say that the Urban Decay Eyeshadow Primer Potion in Eden ($20, urbandecay.com) can change your life but it comes pretty darn close! It transforms any shadow into a super long-wear, totally crease-free color. I put it on in the morning—yes, it’s an extra, but worth it, step—and my makeup doesn’t budge all day. I tap it on my lids and up to the brow bone until I feel it dry down to a matte finish then I layer over my regular eye shadow. I’ve even started using it under my eyes as well to help hold my concealer in place.
