Longest lasting primer that barely smudges even after a long night! It seems oily, but it is somehow designed to stay put. A little goes a long way.

One and only con: Product design is poor--a lot of it gets stuck around the fat part of the tube so you'll have to dig it out with a Q-Tip or cut it up :(

Sometimes I really like to splurge on some long-lasting items and Urban Decay's primer potion is one of splurge buys that is really worth your money. Most of time, using a nude foundation as a base works fine but if you want a tried and true formula, this thing works so effortlessly well.

Packaged in a precious, genie-like bottle, Eyeshadow Primer Potion is an ultra-sheer, totally nude eye base that glides on with the wave of a wand and then disappears instantly. It's the ultimate eye prep for smoother, longer-lasting, crease-proof eyeshadow.

It's amazing. Gives your shadow hat extra punch and lasts for the whole day!! MUST HAVE!!! (via eksy)

This is the only product I could find that will keep eyeshadow looking bright and crease free on my oily lids. Only a small amount of product is needed, so even if you use this everyday, like I do, this will still last you a good amount of time. (via Sephora)

Amazing! it does exactly what it promises to do. and urban decay eyeshadows don't work well without it (they rub off too easily). BUT beware! it's soo good that once the shadow is on, it's not coming off! so no room for mistakes.

I swear by this primer. It tops all the rest.

After going a year or so without any eyeshadow primer, this is simply a miracle for me. I've never had my eyeshadow look just as perfect at the end of the day as it did when I finished it... and I am psyched! It even keeps cheap drugstore quality eyeshadow looking its best, and that makes me one very happy girl.
