I always thought eyelid primers were useless, until I decided to spend a few dollars on a cheap elf one. Then I realized where has this elf eyelid primer been all my life ???
It's pretty much skin coloured, so it does help with discolouration on your eye lids, basically how I would describe it as is something, that the eyeshadow sticks to, and perfects all the imperfections.
The applicator is very nice, and the formula itself is very sheer, and glittery. But the fact it costs a few dolllars, and it works the way it does, is a wow, I would happily pay more for this :)
I got this from iHerb, which makes it much more affordable than KMart (given you're getting a few things to make it worth the shipping!) and I really enjoy it - I find that it's nice and thin in consistency and so applies evenly, and really ensures that my eyeshadow (even cream shadows!) doesn't crease. The packaging is nice and simple and has a doe foot applicator.
Tips: A little of this product goes a long way!
