Their are several on the market today that live up their promises, as their are several that do not. Their are several on the market that also mislead you into believing they actually do work, when they really do not match up to other eyeshadow primers.
I think one of the best is definitely Too Faced Eye Insurance because the product goes on smooth and dries to a nice finish, without irriating the eye area. This product is very long lasting and allows your eye make-up to stay put throughout most of the day.
Girlactik eye base is a great eye primer and works well, as is Urban Decay's primer potion, but these two great primers do not work as well as Too Faced Eye Insurance because Girlactik has a tendancy to be a little too sticky based and takes longer to dry and Urban Decay's primer potion tends to dry out quicker, although possesses a great result and promise of most marketed eye priming products.
MAC's paintpots work great as a base and although work as a primer for most girls, however; it has a tendancy to crease, especially if one is of an oilier skin type. Same with any kind of paintpot by any other cosmetic entity.
I am not a fan of MAC's prep + prime, but do believe their other products exceed that product much more so, as a result.
Art Deco Eyeshadow base is great and works wonderfully, but has a tendency to fade throughout the day. Benefit Lemonade primer also is on the same wavelength. Much better than MAC's prep+prime, but not as strong as Girlactik Eyebase or Urban Decay's Primer Potion, as well as, Too Faced Eye Insurance.
