This product is average compared to other eye primers on the market. It does increase the intensity of my eyeshadow, with that being said, it creases like crazy! Even if I set the primer with powder and then apply my eyeshadow over top, my eyeshadow is still completely creased at the end of the day.

For the woman who first reviewed this product, try Coastal Scents CamoQuad concealer as an eye shadow base. Amusingly, it doesn't work well as a concealer, but it does work wonders for me as an eye primer. I believe it's still around $5 and has 4 colors. It goes really far and shadows cling to it. I haven't experienced any creasing with it whatsoever. It'll last you forever and won't break the bank.

I tried this primer from MAC (always ask for a sample before laying out the cash on their often overpriced products) and found that it didn't work any better than the Coastal Scents product. This one actually works better and is far cheaper. For me, anyways.

The other thing you may not be aware of is that you can take your MAC products back at any time if you're not satisfied with them. I've returned so many of their products for exchanges or refunds, even without my receipt and even their products that I bought overseas. I'm notorious for losing receipts and can't be bothered to hang on to them, quite honestly. Don't waste you money. Go get it back!

Back before I realized the saving makeup grace that is eye primer, I had to struggle with those annoying mid-day eyeshadow creases that looked oh-so glamorously oily and mangled on my eyelids. When I found out that primer was the answer, I paid (and literally ending up paying) for a visit to my local MAC store. There, a kindly salesgirl led me to my solution: the MAC Prep Prime Eye (in Light). "This will help to keep your eyeshadow on," she informed me. For a five-gram jar, the price was expensive, but what can a girl do? I ended up spending my birthday money on it, and was on my way.

A couple of days later, when I had the opportunity to use it, I discovered it was not all as great as it seemed. For one thing, the primer looked and functioned too much like a concealer. When I applied it to my eyelids, it began to crease, which ironically, defeated its purpose. While it did not compromise the colour of my eyeshadows, its staying power is a measly four hours at best before it begins to crease.

As it happened, I ended up buying Urban Decay’s Eyeshadow Primer Potion to help combat my problem. Reluctant to throw away the MAC primer, I still use it at times as a concealer, but never again for its priming powers (or lack of).
