How do I get rid of dark under eye circles?

I get at least 9 hours of sleep everyday, drink tons of water, but they are still there! I'm pretty sure it is hereditary since my mom and grandma have them too. I just tried the tea bag trick, but i don't think they were cold enough, and tea got in my eye, so I will try that later. I also have a eye gel mask that you wear at night. They make me look 10 years older. What should I do to get rid of them?!
