Query: Amazed!

I know this will sound unbelieveable, but within a few days of using this cream my under eye circles are way lighter and my under eye bags have almost diminished! When I read the reviews for this cream, I decided to give it a shot because I have always had dark under eye circles since I was a kid (genetics) and lately (in my thirties) under eye puffiness. I didn't think it would work so fast and be so effective! I will definetly keep using it!
