Plastic surgeons and even med spa physicians offering Restylane and Juvederm would be well intentioned to make sure that they understand the cannons of what beauty actually is. In many ways it's the elimination of asemmetry or extra 'noise' like wrinkles or pigment.
Via CNN: It's hard to pinpoint what distinguishes a gorgeous face from an average one, but some researchers are getting pretty close. Psychologist Lisa DeBruine, Ph.D., of the University of Aberdeen in Scotland says she's found that women's faces get more attractive to men when they are ovulating. "We're not entirely clear why there's this difference, but we think that the women might look healthier, have a bit of a healthier glow when they are ovulating."
Symmetry is another factor that determines a face's attractiveness. Kendra Schmid, an assistant professor of biostatistics at the University of Nebraska Medical Center, says there is a formula for the "perfect" face. She uses 29 different measurements to determine someone's appeal on a scale of 1 to 10.
To start, Schmid says the ratio of the length of the face to the width of the face should be 1.6, also known as the golden ratio."The face should also be divided into three equal pieces vertically," she says. "The forehead, then [the bottom of the forehead to] the nose and then from the nose to the chin."
Who's face is the most "perfect," according to Schmid's measurements? No big surprise here! "Brad Pitt's is the highest that I've ever used the [formula] on," she says. "He was a 9.3 [out of 10]."
Brad's partner, Angelina Jolie, didn't fare too badly either. "Angelina was a 7.67, and that's pretty high," Schmid says. "Most people rate about 4 to 6. ... The thing that is probably lowering her score is the thing that she's most famous for -- her full lips." Schmid says that ideally the width of a mouth should be twice the height of the lips.
Other celebrities Schmid tested were Halle Berry, who scored a 7.36, and Hugh Jackman, a 6.45. "There's never been anyone who was a perfect 10," Schmid says. "If you're out there, we're looking for you!"
