Eyeshadow primer, the best thing I never knew about. Put this on before your eyeshadow and your make up will be flawless all day. No smudging, no crease lines... so awesome. Urban Decay - Eyeshadow Primer Potion
It didn't seem like Original Eye Shadow Primer Potion could get any better, but Urban Decay found a way. Revamped packaging that includes an applicator, this legendary primer looks more gorgeous and applies with more versatility.
Primer Potion, Urban Decay- This is the most expensive make-up product I own ($20). It's a little bottle but it is well worth it. It keeps my eyeshadow on all day and I'm about out of my current bottle but I got about six months worth of wear out of it! Buy it! Love it!
