Contrasting facial features key to determining age new research says
We recently came across some interesting new research by Psychology Prof. Richard Russell of Gettysburg College, who has been collaborating with researchers from CE.R.I.E.S. (Epidermal and Sensory Research and Investigation Center), a department of Chanel Research and Technology dedicated to skin related issues and facial appearance.
The contrasting nature of facial features is one of the signals that people unconsciously use to decipher how old someone looks, says Prof. Russell.
In one study, Russell and his team measured images of 289 faces ranging in age from 20 to 70 years old, and found that through the aging process, the color of the lips, eyes and eyebrows change, while the skin becomes darker. This results in less contrast between the features and the surrounding skin -- leaving older faces to have less contrast than younger faces. In another study involving more than a hundred subjects in Gettysburg and Paris, the scientists artificially increased these facial contrasts and found that the faces were perceived as younger. When they artificially decreased the facial contrasts, the faces were perceived as older.
"Unlike with wrinkles, none of us are consciously aware that we're using this cue, even though it stares us in the face every day," said Russell. The discovery of this cue to facial age perception may partly explain why cosmetics are worn the way they are, and it lends more evidence to the idea that makeup use reflects our biological as well as our cultural heritage, according to Russell.
