Sephora Immediate Wrinkle Filler

Yep. This stuff is awesome. It feels a lot like that L'Oreal primer that came out a while back. Its $20 for .42 oz and you can actually use it as an all over primer. A little goes a long way. I use it under my eyes primarily, but it REALLY makes your make up stick, and for under eyes, where concealer goes - its awesome as concealer has this funny habit of melting. From Sephora's website :

-Silicone elastomer: Makes skin soft, silky, and smooth.
-Vegetable cellulose: Has a mattifying effect.
-Silica: Controls and balances sebum production to prevent shine throughout the day.
