4. Have some fine smiling lines around your lips? You can apply your eyeshadow primer there before foundation if you don't want to use all over face primer, this will smooth out that area and prevent foundation from getting in those lines! Make sure eyeshadow primer is matte, you don't want any unwanted shimmer around your lips.
5. You can also use it as a concealer if primer is in "concealer color" and has no shimmer.
If you have any other ideas how to use an eyeshadow primer and how do you use it, please, share it with the world in a comment ;)
