Despite various aesthetic trends, the ideal lip proportion and lip volume remains elusive.

Thus, the aim of this study was to investigate the aesthetic perception of various lip shapes to identify the most attractive lips.

Fifty-nine White study participants with a mean age of 32.73 ± 9.4 years were asked to assess lips of various proportions and of various volumes.

Gaze assessment and aesthetic rating of the same set of modified lip images were performed.
