Facial attractiveness decreases with age from 11 to 31, but individuals maintain their relative attractiveness. Smiling and a youthful appearance enhance female attractiveness, while orthodontic treatment offers limited long-term benefits.

Area of Science:

  • Psychology
  • Human Development
  • Aesthetics

Background:

  • Facial attractiveness is a complex trait influenced by numerous factors.
  • Understanding developmental changes in attractiveness is crucial for various fields.

Purpose of the Study:

  • To investigate factors influencing facial attractiveness across a 20-year period.
  • To examine changes in perceived attractiveness from adolescence to early adulthood.

Main Methods:

  • Longitudinal study of 60 individuals from age 11 to 31.
  • Facial photographs (smiling/non-smiling) assessed by 12 judges using a 9-point Likert scale.
  • Statistical analyses including univariate, multivariate tests, and generalizability theory.

Main Results:

Related Experiment Videos

  • Facial attractiveness generally declines between ages 11 and 31.
  • Smiling and a youthful appearance significantly increase attractiveness, particularly in women.
  • Individuals tend to maintain their relative attractiveness rankings over time.

Conclusions:

  • Facial attractiveness is multifactorial, not dependent on a single feature.
  • While orthodontic treatment improves dental aesthetics, its long-term impact on overall facial attractiveness is limited.
  • Orthodontic interventions may offer greater perceived benefits for individuals with lower childhood facial attractiveness, especially males.
