Researchers at Wake Forest University in the U.S. found that one in five men prefer to see women with natural make-up day or days without one. According to the survey, almost 90% of women never leave the house without make-up. In most cases, this refers to going to work. One-third of respondents said that even women in the store would not go without makeup. Around 64% of respondents do not go to work without being smeared at least basic ointments, and 44% had never photographed without making themselves "beautiful". Women use cosmetics not only to attract the opposite sex, but also to hide their skin imperfections.
