SYDNEY, Australia: Research shows that facial attractiveness can significantly influence social decisions, including those related to dating, recruitment and even legal judgments. Given that the underlying mechanisms of facial attractiveness are still not fully understood, a recent study has investigated whether changes in lip size affect how male and female faces are perceived. The findings revealed gender-specific biases in perceptions of lip attractiveness and underscored the potential influence of cosmetic procedures on prevailing beauty standards and the development of lip-related dysmorphia.
