Hey everyone! I have to know… What do you use for a primer for your eyeshadow. Apparently the new way of priming your eye lids is to use concealer instead of an actual primer. I use primer and not concealer. I believe that if I put concealer on as a primer it is adding a thicker layer on the lids then what primer would. 

I want to know which one do you use primer or concealer?

Why do you prefer it?
