You will notice that at the beginning of every eye makeup tutorial i always say in the very first step to prime your eye lid,girls this is a MUST! It is so important to do this step for a number of reasons:
-They have a sticky-ish texture to them,there fore your eye shadow will last longer and appear brighter and more true to tone.
-They prevent creasing which occurs when the eye lids get oily (your eye lids are the oiliest part on your face) so when they get oily the eye shadow will appear "creased" and the eye shadow will wear off and flake.
I use either the "F.Y...eye!" by Bennefit or the Eye shadow "Primer Poition" by Urban Decay,there are different variety's of these as they have different colours,my favorite is the one named "Eden" which is the first Urban Decay one pictured,because it is a skin colour,like a mini concealor as it evens out the skin on the eye making it the perfect base.
What Urban Decay say about their primers:
Our Eyeshadow Primer Potion promises long lasting, crease-proof, more vibrant eye shadow. And our travel sizes mean never going without your favorites! Each shade offers a little something different but ALL deliver mighty performance.
Introducing travel-size versions of our beloved Eyeshadow Primer Potions! These are MUST-HAVES for serious primer junkies and primer-newbies alike. Each gorgeous formula has a different desirable finish, but ALL give you eyeshadow that lasts, more vibrant color, and absolutely NO creasing! Their go-anywhere sizes mean never having to go without your trusted Primer Potion. Apply to lids before shadow application. It dries down almost instantly creating smooth lids that are super powered eyeshadow magnets.
So guys whatever you decide to do i would highly reccomend using a primer on your eyes,you dont want your beautiful work to go to waste!!! I also hope this helps you to understand eye primers a little better and know what they do when using them :)
