Researchers at the University of California in America asked groups of men and women to assess the attractiveness of 160 pictures of white women’s faces. They found that a 1:2 ratio of upper to lower lip was considered the most attractive by both sexes.
Ideally, the lips should make up about 10% of the lower third of the face. For those considering lip fillers, these indings should be adhered to in order to preserve a natural look.
If you’ve ever seen someone with “fake” looking lips it’s because they’ve broken the golden rules of ratio and proportion. Women who increase the size of their lips by more than 50% risk leaving their face looking out of proportion. Meanwhile, those who overill their upper lip will create an artiicial, “duckbill” appearance.
The authors of the study concluded: “We advocate preservation of the natural ratio or achieving a one to two ratio in lip augmentation procedures while avoiding the overilled upper lip look frequently seen among celebrities.”
The Cupid’s bow
To be considered truly attractive, lips must not only be full, but also shapely. As one London-based doctor, Dr Tijion Esho, points out, the 1:2 ratio should not extend the entire width of the lips. The perfect lips will have a 1:1 ratio in the outer corners - plus an accentuated philtrum, or Cupid’s bow. To create a really sensual look, the bottom lip should be plump in the centre while the top lip should be “dipped low” in the middle, like can be seen in Angelina Jolie’s famous pout. The shape can be achieved during lip augmentation by careful placement of small droplets of lip filler.
