Alter some Images - The way jaw bone loss affects humans face

Often, people who are missing teeth look older than they really are. The reason is the loss of jawbone that inevitably follows tooth loss. With the full teeth loss, the jaw bone shrinks and gets thinner overtime leading to the greater angle of lower jab bone, nose tip goes down, nasolabial fold gets much deeper, lip corners and even the eye corners slip down. The lower third of face diminishes and face muscles flabbiness occurs which leads to premature aging/ aged (senile) face expression. We need an image that will show human's half face with healthy teeth, with jaw bone that just started to disappear (face looks a bit older), and with completely lost jawbone. Please look at some examples: [login to view URL] [login to view URL] [login to view URL] To visualise this process even better I suggest drawing angles and/or arrows on changed parts of the face (little example of the idea in file attached) Is it possible to take a face photo and using drag tool make it look older? Or is it easier to "draw" the jaw bone loss effect? Looking forward to hear from interest6ed professionals!
