Facial Expressions Affect Photo Comparability

Researchers report in a new study that 16 facial expressions and head positions significantly impact malar and jowl volumes, with smiling and frowning having the biggest effects. Facial volume changes from expressions can look like results seen from aesthetic facial rejuvenation procedures.

Researchers also identified a combination of soft tissue surface landmarks—glabella, bilateral cheilion, pogonion and laryngeal prominence—that plastic surgeons, dermatologists and others can refer to in order to standardize 3D image use.
