What does "Inner Beauty" mean to you?

Today I've been thinking much about it. How do you recognize it? I mean it's not the things like make up and other stuff we put on artificially to look better... So I came to the conclusion that to me it becomes visible through an honest and strong smile and even more through a certain reaction you would not have expected from someone - showing their deep sympathy for you and others. That's when I can see their light shining.
