How do you stop the creasin'?

I have come to realize that there are two camps when it comes to eyeshadow, either you have never owned an eye primer in your life OR your in the camp where you use a primer daily and can't remember how you lived life without one.

As you can tell from the above image I am in the latter camp - I like to use an array of products to combat the oily eyelids. 

For days where I'm keeping my eyes quite natural I use either a sweeping of translucent powder or just a sheet of blotting paper. That is enough to keep my eyelids oil-free for the day. 

However if I use more than one eyeshadow or I want something abit heavier I turn to my trusty Primer Potion - I personally swear by this and I know alot of other do too, but I also know this doesn't work for alot of people either! However I do find using a concealer or abit of foundation works in quite a similar way. 

Then if I want super staying power I use an eyeshadow base - either the stay perfect eye mousse or a creaseless cream eyeshadow by the Balm, which works exactly like the Benefit ones. For me, once these dry and you have your eyeshadow over the top they work perfectly. You have to work at blending more with the eyeshadows but using a cream base always works great and also makes the eyeshadow more pigmented.

But what I want to know is how you stop your eyeshadow from creasing!
