How To Reduce Dark Circle?

Okay, so im 14 and i have really bad dark circles. Im not sure if tey are hereditay but my brothers and my mom has them. Its really annoying. Ive tried cucumbers and sleep or what ever but it doesnt help. Does drinking carrot jiuce, or tons of water help lighten them. My brother is 16 and his arent that dark. Also i dont drink any soda, just in case if that would be a prolem. Oh, and big brother is anemic and so is my mom. If your a docter then can you plz help me find a way that actually lightens dark circles.
