Abstract
Faces are central to human interaction, serving as primary sources of identity, emotional cues, and social judgments. Facial attractiveness is strongly linked to perceptions of trustworthiness and moral goodness, leading to preferential treatment across education, employment, and legal contexts. Deviations from facial norms-such as asymmetry or visible differences-are, by contrast, often associated with negative traits, social avoidance, and dehumanisation. Across cultures and centuries, deliberate facial disfiguration has been used as a form of punishment for perceived moral or legal transgressions. Evidence from ancient Egypt, Mediaeval Europe, and early modern legislation, as well as modern acid attacks, indicates that intentional facial disfiguration has long served as a means of ongoing punishment through humiliation and identity disruption. Motivations for targeting the face may be rooted in its central role in identity, beauty, symmetry, and symbolic purity. Despite contemporary legal efforts to curb acid attacks and related violence, legislation specifically addressing intentional facial disfiguration remains limited. Modern psychological research confirms that acquiring a facial difference can severely impact quality of life, social functioning, and identity. This paper synthesises historical, cultural, and psychological perspectives on punitive facial disfiguration, highlighting its enduring role as a mechanism of social control. Future research should examine perpetrators' decision-making, possible differences between different types of facial disfiguration, and the perceptual and emotional consequences of different facial injuries to inform prevention strategies and improve support for victims.
