Fig 1. Some well-characterized features influencing perceptions of facial attractiveness.

Depicted are physical traits that influence facial attractiveness through changes in shape (e.g., adiposity, averageness, masculinity/femininity, and symmetry) or color (e.g., complexion), as well as qualities influencing facial attractiveness that might also be inferred from both shape and color information (e.g., youthfulness, health, and personality). Relationships between each of these features and attractiveness are likely mediated by a host of biological factors influenced by genotype.
