A new study out recently found that wearing makeup not only boosts a woman's attractiveness, but it also increases people's perceptions of her likability, her competence and her trustworthiness. The study, paid for by Procter & Gamble (which sells CoverGirl makeup) and designed and executed by researchers at Boston University and the Dana-Farber Cancer Institute, used photographs of women of various races wearing different amounts of makeup. Each woman was photographed with no makeup on, "natural" makeup, "professional" makeup, and "glamorous" makeup. Participants (men and women) were then asked to judge the women. Those women who had on makeup were judged as more competent. likable, and trustworthy than the barefaced women. Read more about the study and what the researchers found.
