Indented line/curve down middle of nose (Photo)

Unless a n examination is performed, it will be very hard to pinpoint why you have this curvature, as it can be from one, or multiple anatomic deformities. I would consult a specialist in your area.

Sometimes a small amount of filler can be used to modify the contour of the nose and redirect light and shadow on the face so that the defect is not obvious.  If you are looking for a complete reshaping of the nose, I don't believe filler will be helpful. If you are looking for slight improvement, there may be slight possibility that filler like Juvederm will help from what I can tell in the photo. See a cosmetic surgeon/injector who treats noses and he/she can guide you.  Best of luck.

Hi,  We are our genes but also our environment.  Asymmetries are normal on the face and nose but I bet you at some point you have fallen and hit your nose on something.  It could have even been as a toddler learning how to walk.  What matters is solutions.  While surgery is classically the method of choice, based on this one limited photo it looks like you would possibly be a candidate for a non-surgical nose job to inject the indented area and the bridge giving you a nicer nose.  I do need more pictures of various angles to tell for sure though.
