My all time favourite lid primer is my Silk Naturals one. This is a sticky base that ensures loose shadows adhere. The primer is clear, so does not offer an even coloured base. I am finding this necessary, as my lids' skintone is quite uneven.
I haven't had a lot of experience with the Elf range, but being such a budget brand, I decided to give their eyelid primers a try.
The eyelid primer offers lid preparation to not only make a smoother surface for even makeup application, but also increase longevity.
I am using the shade "Pearl" in the attempt to give my eye shadows more vibrancy.
The primer comes in a handy sized tube.
The product is a lot thicker than I expected.
To apply, I simply use the included doe foot wand, then blend out with my finger. It sheers out quite a lot, but really seems to help with my creased lids.
When using loose eye shadows, I still use my sticky primer, but I'm finding that beginning with Elf Eyelid Primer makes for smoother surface.
I've got a couple of others to try before making a decision as to whether or not I'll buy this particular one again, but for a few dollars, it's quite a good product :)
