Hello, thought twin...
I just realized that what I was using under my eyes wasn't really cutting it at all, so this weekend I went to Sephora and spent lots of time looking for a good concealer. I am really fair (NC15) and ended up choosing a tiny Stila under eye concealer pot in Light. I really like the formula (and no, I am not a huge Stila fan) because it is really creamy and easy to blend, yet it stays in place.
HTH!
