Hi Bowsa... I'd love to know the answer to this too! I've been told it can be a sign of iron deficincy (though I've been tested and that's all good). I've also been told exercise helps, but I do that too. Also it's a sign of dehydration, but I drink lots of water.... I think some of it's in the genes, my little sister has it too, have you always had them or is it a recent thing? The area under my eyes is always slightly dark, just sometimes worse than others. I tend to put lots of concealer and highlighter under them during the day and cover them in eye cream at night (which I think has helped)
EDIT: Just noticed your profile says "Dad" so concealer and highlighter are probably not in your list of options!!!
