The finding, from the Face Research Laboratory at Aberdeen University, challenges previous studies that have attributed attractiveness to physical characteristics —— such as a preference for symmetrical faces, large lips in women and strong jaw lines in men.
Dr Claire Conway, author of the study, which was published in the Proceedings of the Royal Society on Wednesday, said that maintaining eye contact and smiling makes you more attractive.
Conway and fellow researchers analyzed the effect of gaze direction, facial expressions and gender on attractiveness.
Participants were found to be more attracted to happy faces, looking directly at them and of the opposite sex.
"Here, we show that gaze direction can also be important for attraction.“ the researchers said.
"Faces that were looking directly at the viewer were judged more attractive than faces with averted gaze.
"This shows that people prefer faces that appear to like them and that attraction is not simply about physical beauty."
