This is an article on study done in Scotland on how the Estrogen affects the attractiveness of women.. and how make up is basically used to demo heightened fertility rather than just fashion!
Beauty, as it turns out, isn’t skin deep. A study at the University of St. Andrews in Fife, Scotland, has shown that attractiveness in females relates to the hormonal composition of blood.
(These are composite images of the faces of 10 women with the highest level of estrogen and 10 women with the lowest levels.The composite image of 10 women with high estrogen levels is on the left. Men chose it as the most attractive in the study.)Researchers found that men tend to be attracted to women who have high levels of estrogen, a naturally occurring sex hormone linked to fertility. The report also found that women with high estrogen levels had more feminine features, such as bigger eyes, fuller lips and smoother skin.
The researchers photographed 59 women between 18 and 25, who were wearing no makeup, and took a urine sample from each subject for hormone analysis. A group of men then rated the women in the photographs for health, femininity and attractiveness.
The results showed that men were most attracted to the women who tested for high levels of estrogen. Miriam Law Smith, who helped carry out the research, says men were, in effect, choosing the women best poised to bear children.
“From an evolutionary point of view, it would now make sense that men prefer feminine female faces because those are the women who have higher estrogen levels, and who are ultimately more fertile,” says Law Smith. “In our evolutionary past, men who favoured women with feminine features would be choosing the more fertile female, thus would have had more babies and be passing on more of their genes.”
The study also suggests cosmetics do much more than merely add a touch of colour to a woman’s face.
Law Smith believes women wear makeup to mimic the facial cues that allude to heightened fertility. A woman with low levels of estrogen, then, would be more likely to wear more makeup.
