The digital images were registered and landmarked, and the surface contours were averaged as in previous studies. Novel methods of analysis were applied to create vector maps of skin displacement as well as landmark tracking with age over the entire face.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Most of the surface of the model, and by extension the facial skin, flows from superior to inferior relative to the nasion. The entire upper face and cheek down to the level of the nasal base shows minimal displacement, 0 to 2\u2005mm, and then stretches progressively to the jawline. Retrusion of the lips is a major definer of the nasolabial crease\/fold complex. Weight has a major effect on the vectors of facial shape.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Cheeks age largely by progressive inferior flow of skin. The nasolabial crease is greatly influenced by retrusion of the lips. Other previously described shape changes are confirmed and visualized.
