Most people have asymmetry in not only their faces, but their bodies. However, researchers have discovered that the more symmetrical a person is, the more beautiful they are considered to be. One of the reasons Elizabeth Taylor is considered so beautiful is because the two sides of her face are virtually symmetrical.
There was a series on one of the educational channels regarding this. The research of Dr. Stephen Marquandt was part of the basis behind the series. He has a very interesting web site at
http://www.beautyanalysis.com. In there, he also discusses the Golden Section which Karin Wells has earlier posted on here. The page is hard to read because it's in frames, so I'm giving the url without frames here:
