great product. makes eyeshadow go on smooth and lasts all day. does not crease and works great. the only thing is the packaging sucks and for 16 dollars that packaging REALLY sucks. my bottle cracked on the bottom like the first day i got it, it started drying out. but i brought it back to life. haha. i had to pour a little hot water into the bottle, kind of shake it up and then put it in a zip-lock bag. after doing all of this it worked fine and stopped drying out. to make a long story short, i will keep buying even though the packaging sucks. the product is awesome.

Love it. Works good, almost too good. I have to be careful to blend my shadow very carefully. Once I get everything place it lasts all day. I particularly like to put a little under my bottom lashes to keep my liner from fading away, like it tends to do. You don't get a lot of product for the money, but I will keep buying it anyway.

I love this primer. It works great. I can put it on in the morning and at the end of the day my eyeshadow is still in place and looking great. I will buy again.

This really does the job. Shadow lasts all day with no creasing and loss of intensity. Just like all the reviews say. I took off a lippie though because I must say the packaging sucks! While it looks cool, there's too much wasted product. A girl shouldn't have to risk cutting off her fingers to get her money's worth out of a product.

This is the first eye primer that I've ever used; bought it after lots of girls recommended it in another forum I browse in. I'm Asian and have the single eyelid, so I was having problems with the eyeshadow creasing. When I used UDPP, the eyeshadow stayed on all day and most importantly, there was no crease. Amazing. It's a little pricey at around $15 a bottle, but a little goes a long way. Plus, just look up "UDPP" on YouTube and there are lots of videos that show you how to cut open the bottle to get a LOT more out of your bottle!

Edited to increase the rating on packaging quality, since Urban Decay has changed the packaging from that ridiculous bottle to a squeeze tube! Hurrah!

I agree with every other positive comment about this product. I want to add that it is also perfect for when you want to apply eyeshadow wet as a liner. Whenever I had tried that tip before it had never worked, but after UDPP I can apply *any* eyeshadow as a liner and it *stays* all day. (update) I just went swimming and my eyeshadow stayed on! This stuff is incredible.

This is great if you have oily eyelids or have a problem with glitter flecks staying put. It's a nude colored cream that dries invisible under your shadow and doesn't crease. The packaging is adorable (it's a purple genie bottle) and it has an applicator wand so you don't have to use your finger

This primer works wonders. It has such great sucking and lasting power that it holds onto any eyeshadow and eyeliner you put on. Can't say that I like the packaging much though. A lot of product comes out with the wand and a lot end up being wasted because of the bottle. However, I can't go without using this when I put on eye makeup products. Works like a charm!

Love this stuff. HG. My eyeshadow and eyeliner go nowhere.

This stuff is great!! i use mine almost every day. This stuff literally cements your eyeshadow to your lids, so be ready to really scrub to get it off. It makes your eyeshadow super blendable and gives what ever color you use a little kick. It intensifies it. Great staying power. The only problem i have experienced is if i wear it everyday, it starts to itch my eyelids (it has an anti persperant in it- so your lids dont sweat) It kind of dries them out if you use it too much. But other than that, this stuff is super awesome!!
