I've just turned 21 (though my gaunt face makes me look a bit older) and I've recently developed an odd indentation just below the tear trough. It's in between the tear trough and the nasolabial folds. You can see it in the photo (sorry about the low quality). To me it appears like the fatty tissue has simply started to atrophy, but I'm not a doctor. Is there any precedent for treating something like this?
