Is the woman pictured on the right more attractive than the woman on the left?
The photograph on the right was changed using a new "beauty making" computer program, which
uses a mathematical formula involving 234 measurements of distances between facial features to get a
theoretically more attractive version, while keeping the basic appearance of the face unchanged. Unlike
changes done in fashion magazine photos, wrinkles were not smoothed and hair color was not changed.
The program is the latest attempt to combine beauty and science, a subject that has drawn increasing
academic interest in the last decade.
Studies have shown there is surprising agreement among people of different cultures about what
makes a face attractive. Most important is symmetry (匀称), along with youthfulness, skin smoothness
and vivid eyes and hair color. Yet, like the many other scientific or mathematical attempts to define
beauty, this software program raises complex and difficult questions about the understanding of beauty.
"How can they prove something is more or less beautiful?" said Lois Banner, a history professor at
Chicago University, who studies changing beauty standards. "There can never be a single standard of
beauty because so much of it is culturally influenced."
After viewing "before" and "after" photographs of different people, Banner said the original faces
were more attractive. "Irregular beauty is the real beauty," said Banner, adding that attempts to measure
beauty are driven by the media's efforts to define beauty and who is beautiful.
Martina Eckstut, the woman whose photo was beautified for this article, said she was struck by how
different she looked. "I think the 'after' picture looks great, but it doesn't really look like me at all." She
added, "I would like to keep my original face."
For centuries people have tried to define a universal ideal of beauty. "The first reaction we have to
faces will be based on face symmetry." said Alexander Nehamas, a professor who has written about
beauty. "But in real life we don't just see a face. We see faces as people express their emotions and
ideas, and all those aspects of the face are essential to our deciding whether a face or a person is
beautiful."
