From the Guidelines
Physical attractiveness is determined by a complex interplay of biological, psychological, and cultural factors, with facial symmetry, clear skin, and features signaling health and genetic fitness being universally appealing across cultures. The perception of attractiveness can have significant implications on an individual's mental health and quality of life, as evidenced by the psychological burden of facial paralysis, which can lead to impaired interpersonal relationships, social distress, depression, and social alienation 1.
When considering the determinants of physical attractiveness, it is essential to recognize the role of cultural standards, personal preferences, and individual experiences. Cultural standards of attractiveness vary across societies and change over time, influencing what is considered attractive 1. Personal preferences also play a significant role, as individuals develop unique attractions based on their experiences, exposures, and psychological makeup.
Key factors that contribute to physical attractiveness include:
- Facial symmetry and clear skin
- Body proportions that reflect fertility and health, such as the waist-to-hip ratio in women and shoulder-to-waist ratio in men
- Behavioral characteristics like confidence, kindness, and a sense of humor
- Cultural standards and personal preferences
- Familiarity, scent, and voice, which can subtly contribute to attraction through biological signals
It is crucial to acknowledge that attractiveness is multifaceted, combining universal biological preferences with culturally specific standards and individual variations, making it both objective in some aspects and deeply subjective in others. The most recent and highest quality study on this topic is from 2024, which highlights the importance of differentiating between normal appearance concerns and body dysmorphic disorder (BDD) in young people 1.
In the context of real-life clinical medicine, it is essential to prioritize the psychological well-being and quality of life of individuals, particularly those with conditions that affect their physical appearance, such as facial paralysis. Therefore, a comprehensive approach to addressing physical attractiveness should consider not only the physical traits but also the psychological and cultural factors that influence an individual's perception of themselves and others.

Determinants of Physical Attractiveness
The determinants of physical attractiveness are complex and multifaceted, involving various factors that influence how attractiveness is perceived. Some of the key determinants include:
- Physical features such as facial attractiveness, body shape, and body mass index (BMI) 2
- Non-visual modalities such as acoustic and olfactory cues, which can strongly influence perceived attractiveness 3
- Personality traits, clothing, and other non-physical factors that can influence attractiveness judgments 4
- Cultural and environmental factors, which can affect what is considered attractive in different contexts 2, 5
- The context in which attractiveness is judged, including the presence of others and the size of the group 5
Facial Features and Attractiveness
Facial features play a significant role in determining attractiveness, with certain traits being perceived as more attractive than others. These traits include:
- Facial fluctuating asymmetry, which is related to both self-perceived and male-rated attractiveness 6
- Facial averageness and facial maturity, which affect men's ratings of attractiveness but not self-perceived attractiveness 6
- Facial sexual dimorphism, which can influence attractiveness judgments but is not always a significant factor 6
Group Attractiveness Effect and Cheerleader Effect
The group attractiveness effect and cheerleader effect are two phenomena that influence how attractiveness is perceived in group contexts. These effects suggest that:
