You may believe that your piercing eyes and radiant skin are the features that lure most men, but it turns out they're really fixed on your lips -- and particularly if they're cloaked in red lipstick.

Scientists at ­Manchester University used eye-tracking software to show that in the ten seconds after meeting a woman for the first time, the average man will spend more than half that time looking at her mouth, according to a report in the Daily Mail.

"For centuries, women have painted their lips red to enhance their appeal. The practice dates back as far as the Ancient Egyptians, who used red lipstick and rouge to enhance their attractiveness." said Dr. Geoff Beattie, who conducted the research.

"Our research suggests that red lips and perceived attractiveness are still ­inextricably linked, with red lipstick the most powerful attractor, and one that ­significantly increases visual fixation," added Dr. Beattie.
