"Women with facial proportions that are closest to average are considered the most beautiful by their peers, research suggests.”
“Though it is unknown why faces that follow these proportions are considered lovelier, researchers say one theory is that humans have a mental prototype that represents an average of all faces and those that are closest to it are considered the most appealing. Previous research has shown that those with symmetrical faces are also perceived as more beautiful, possibly because the symmetry indicates good health. It is possible that evolutionary biology dictates that average faces are viewed in much the same way, the study authors noted.”

“Researchers from the University of California San Diego and the University of
Toronto asked college students to view digital photos of women's faces that were
identical except for slight alterations in certain facial proportions, including
placement of the eyes and the relationship between the eyes and mouth.”
