Summary
Fuller lips are perceived as more attractive in young women. A statistical atlas revealed that the most appealing lip shapes are fuller, taller, and have a larger surface area than average.
Area of Science:
- Plastic surgery
- Aesthetic medicine
- Facial morphology
Background:
- The distribution of lip shapes in young females and their relation to attractiveness is not well-defined.
- Investigating lip morphology variations and their impact on perceived attractiveness is crucial for aesthetic procedures.
Purpose of the Study:
- To hypothesize that fuller lips are perceived as more attractive than less full lips in young females.
- To analyze lip shape variations using a statistical atlas and correlate them with attractiveness ratings.
Main Methods:
- Created a statistical atlas of lip morphology from 700 female photographs (ages 18-35).
- Analyzed morphological variations using principal component analysis.
- Assessed attractiveness through anonymous surveys of lip images.
Main Results:
- Developed a statistical model of lip shape variation and its link to attractiveness.
- The most attractive lip shapes were significantly fuller, taller, and had greater surface area than the population average.
- 428 survey responses were collected and analyzed.
Conclusions:
- A statistical atlas effectively visualizes lip shape variations within a population.
- Attractive lip shapes deviate significantly from the population average, supporting procedures that enhance lip height and surface area.

A complete procedure of testing a hypothesis about a population mean when the population standard deviation is unknown is explained here.
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used;...

In the field of psychology, there are several ways to organize measurements of a trait, feature, or characteristic (i.e., variables). Qualitative data, such as ethnicity, can be tabulated into a frequency count to provide information about the proportion, as well as the variety of groups in a sample or population. On the other hand, researchers can perform a wider set of calculations on quantitative data. The mean, mode, and median, for instance, are central tendency measures to identify a...
