TORONTO, ON – Beauty is not only in the eye of the beholder but also in the relationship of the eyes and mouth of the beholden. The distance between a woman's eyes and the distance between her eyes and her mouth are key factors in determining how attractive she is to others, according to new psychology research from the University of California, San Diego and the University of Toronto.
Pamela Pallett and Stephen Link of UC San Diego and Kang Lee of the University of Toronto tested the existence of an ideal facial feature arrangement. They successfully identified the optimal relation between the eyes, the mouth and the edge of the face for individual beauty.
In four separate experiments, the researchers asked university students to make paired comparisons of attractiveness between female faces with identical facial features but different eye-mouth distances and different distances between the eyes.
They discovered two "golden ratios," one for length and one for width. Female faces were judged more attractive when the vertical distance between their eyes and the mouth was approximately 36 percent of the face's length, and the horizontal distance between their eyes was approximately 46 percent of the face's width.
You can see from this one of the limits to beauty enhancement from plastic surgery today. Even if we had stem cell therapies, gene therapies, interference RNA therapies, and other means to totally rejuvenate the face changing facial proportions is another level of problem that involves cutting into bones to shorten and extend bone lengths.
Anyone still alive 30 or so years from now with the money to afford it will be able to go in for a full facial rejuvenation. Grow new teeth. Gradually replace stem cells to generate new skin and collagen layers. New stem cells for the bones will help refill the bones. But achieving absolute beauty will require much more radical changes.
Regardless of how difficult facial reshaping remains in the future ideal beauty will become commonplace. For new babies ideal beauty will increase due to embryo selection but will really take off once embryo genetic engineering becomes possible. Enabled by the massive and continuing declines in the cost of DNA sequencing some scientists will find genetic variants that create differences in facial proportions. Then the problem becomes how to get the right genetic variants into an embryo. Once we can put beauty genes into embryos we are going to have one sexy world.
