This primer did NOT work for me. It made my eyes even greasier than without it.

I cannot get enough of this primer! I just love it. The packaging is great because since it comes with a brush, its hygienic. it really helps improve the shade of my eye shadows and even when I just wear (any) eye liner alone, it helps it stay longer lasting.
This is a really nice product to invest in. I've tries other primers, but always come back to UDPP.

Made my eyelids VERY itchy

The BEST primer! I have very oily eyelids and I am asian so my eyeshadows always crease and smudge everywhere. The only thing that saves my eyeshadow is this primer. Love it! I do have to make sure my skin is well-moisturized though before using this because it can cause dryness. It's weird having dry and oily eyelids :0P

If you don't have very oily eyelids, this primer is very good. It has good staying power and increases the vibrancy of your eye-shadows. It is my go-to primer during the cooler months.

However, during the warmer months, I tend to have very oily eyelids. Therefore, I use the Eden version of this primer; and it is fantastic!!!

The only thing frustrating is that due to its packaging, unless you de-pot the product, you waste a lot of product.

Based on reviews, I expected much more. Although it helps my shadow last longer than it would without a primer, my shadow creases under less than four hours of wear. I have EXTREMELY oily lids so that may be the reason why but for the price, I had high expectations. I'm just using it until I run out. I've recently tried Wet n' Wild's new primer and it works SO much better than this one. It doesn't make my shadow crease after 6+ hours of wear and it's much more affordable.

Holy balls. This item is incredible and reached my Holy Grail Status only after two days of wearing it.

I honestly have noticed a giant increase in the color quality and brightness after using this product. I'm spoiled and have never had an issue with makeup creasing, but I have no doubts this will take care of it.

There is almost nothing to applying this, therefore, I expect it to last a long while.

Bless you, Urban Decay and may this product remain forever.

Good eye primer, does its job well. Even if you don't plan on wearing eyeshadow, just a quick coat of this stuff will make your lids less greasy and give it a nice nude matte look.

I did notice it helped with crease lines on my eye lids. However, it didn't help with my gel liner from smudging :( My eyes must be super oily since this seems to work for everyone. I did not like the packaging. I noticed some purple flakes while doing my makeup and realized that it was the purple layer that kept peeling off and getting on my hands and face while applying makeup. I will repurchase though until something better comes along.

This works pretty well, but it's not the end all be all of primers. I'm sure something less pricey could work just as well, although I did sleep in my eye makeup last night and it still looks decent today. I hate how my mascara flakes into this and then stays there forever. So, yeah, I guess it works.
