BackgroundIn an era where globalization and social media significantly reshape beauty standards, it becomes imperative to delve into the subjectivity of beauty and attractiveness. The lips, a key element in facial aesthetics, not only contribute significantly to perceptions of attractiveness, but also have a profound impact on an individual's self-esteem. ObjectiveTo analyze the influence of ethnicity on aesthetic preferences for lip characteristics, among both male and female faces. Materials and MethodsStudy encompassed a sample of n=231 study participants (153 female, 78 male) with an average age of 23.2 ± 2.8 years, representing ethnicities such as African, Caucasian, Middle Eastern and South Asian. Participants were asked to rate a series of images showcasing various lip variants, providing insights into their aesthetic preferences. ResultsDemographic analysis revealed gender and ethnic variations in aesthetic preferences for all investigated lip parameters. Female participants were 2.42 times more likely than males to prefer no Cupid’s indentation on a female model (p=0.0019). ConclusionsThe study underscores the importance of understanding cultural influences on beauty standards and challenges the notion of a universal beauty ideal. The evolving role of social media trends, such as Cupid's bow indentation elimination, raises questions about the dynamic nature of aesthetic preferences among different ethnicities.
