In findings that may help establish lip augmentation guidelines, researchers have identified the precise measurements for the most attractive female lips.
Lips with a 53.5 percent increase in surface area from the original image with a 1 to 2 ratio of upper to lower lip that make up about 10 percent of the lower third of the face were deemed to be the most attractive, according to the results, which appear in JAMA Facial Plastic Surgery.
“We advocate preservation of the natural ratio or achieving a 1:2 ratio in lip augmentation procedures while avoiding the overfilled upper lip look frequently seen among celebrities,” the study authors conclude.
To arrive at their findings, researchers showed focus group participants images of white women whose lip surface areas were adjusted. Study limitations include the fact that there is no established reference range for total lip surface area modification in the general population. The surface area percentage reduction and augmentation extremes in the morphed faces were generated based on clinical experience of what seemed to be feasible.
