A recent study suggests that preferences for lip size in attractiveness are influenced by the observer’s gender, indicating a gendered aspect to beauty standards. The research, conducted by Australian psychologists, explored how men and women perceive lip size when evaluating attractiveness.

The study, involving 32 participants (half men and half women), revealed that men generally preferred women with naturally full lips, while women favored even fuller lips. Participants were shown 168 faces and given 1.25 seconds to assess the attractiveness of each image.

A sociology professor from the University of Copenhagen suggests that men may have simpler preferences compared to women, possibly explaining the differing preferences in lip size. The professor also noted that women’s decisions to undergo cosmetic procedures, such as lip fillers, may be driven by self-esteem and cultural factors, rather than solely by male preferences. The number of cosmetic clinics has more than doubled in seven years, from 349 in 2017 to 737 in 2024, suggesting that cosmetic procedures are on the rise.

The professor further suggests that personality also plays a role in perceived attractiveness. Studies indicate that outgoing and confident individuals tend to be rated as more attractive, despite the immutable aspects of their appearance. Symmetry in facial features also contributes to perceived attractiveness.

Although initial assessments of attractiveness can be made in a fraction of a second, personality can influence these initial perceptions. However, it is generally acknowledged that attractive individuals tend to have a head start, as there is no known disadvantage to being considered beautiful.
