Dark circles under eyes?

ive had them for quite a while now. i sleep regularly 7-8 hours a day. i am athletic, i work out and eat well and am on schools football team. ( starter on O and D if youd like to know:]). yeah so it doesnt bother me much but i was wonderin if theres a way to reduce them of get rid of them completely. it hasn't always been like this so it cant be hereditary. please help and dont say concealer cuz im not gona try and go gay gay gay.
