Okay so I am 11 years old and under my eyes it's a blackish kind of thing like something you would get from lack of sleep but I tried to sleep it off but it didn't work now its kind of purple and it won't leave on the side of my eye around were my nose is its blue I thought I just needed sleep but its still there now it is all around my eyes its been there for a really long time , I never got punched in the face exapt maybe once when I was 8 or 9 by my sister. But there is no reason that it's there
Do you know what it is?
How can I get ride of it?
Do I need to see a doctor or something like that?

See a doctor or maybe it's how you sleep.

Try concealer. You can buy it a drug store for like, $5. Just put a little under your eyes in the morning.
