After 8 hours at the office or a few hours out at night, my eye shadow used to crease up and would drive me crazy.  My makeup wouldn’t look fresh at all anymore.  About 6 months ago while perusing Sephora, I stumbled upon Smashbox’s Lid Primer and decided to give it a try.  Let’s just say I have never used anything else since then.  It keeps my eye shadow on and looking fresh for my whole day at work and when Im out in the evenings.  I haven’t had to deal with my makeup creasing or coming off.  I highly recommend this product if you are looking for a way to keep your eyeshadow on all day.
