What can I do about tear trough/veins showing under eyes? (Photo)

I'm 23, I always look tired, I realized after looking that I might have a tear trough problem causing the appearance of dark circles. I lost a lot of weight and the gained back I think contributing to the issue .I also have pretty sensitive skin, so I'm worried about doing any procedures (fillers,etc). I'm not exactly sure what needs to be done that's why I posting pictures, hope someone can help, thanks!
