I assume you don't mean that you have the age old issue that people seem to have about it squirting out like mad causing you to use too much, right?
-if that's your issue, that's easily fixed by rolling the crimped end out once or twice beyond how it comes when you first buy it. Do this before you open the cap.... wth this method I've never had that issue that other ppl complain about!
But If you mean you don't put an equal quantity on your lids, I've always found it best to place the small amount on the back of my hand, spread it out a bit there, and then use my ring finger to apply to each lid, building the color up slower so there's an equal amount on each lid. Once that's done, it let it set and then get to work with whatever powder shadows I'm using on top.
I hope that helps!!
