How do I get rid of my under eye folds? Might be dennie-morgan (photo)

I have prominent lines under my eyes that might be dennie-morgan lines. They look awful. People call them wrinkles but I don't think they are because I'm 22 and I've had them since I was a kid similar to the kid in the pix. Not sleeping makes them worse but they stay even I'm refreshed.what causing this?? 1. whats the best overall way to fix this? and 2. whats the best non surgical way to treat this?
