Less is More: Eye-Tracking Reveals How Nose Noticeability Influences Facial Attractiveness.

[INTRODUCTION] Facial attractiveness significantly influences social perception. While prior studies identify the eyes and mouth as primary focal points of attention, the role of nasal aesthetics in overall facial attractiveness remains understudied. This study examines the relationship between nose shape, perceived attractiveness, and visual attention using eye-tracking technology.

[METHODS] Thirty-four models (mean age 38) and 31 observers (mean age 33) participated. Models underwent standardized 2D/3D imaging, and 17 anthropometric facial measurements were recorded. Observers viewed these images on an eye-tracker, recording fixation durations and revisit counts for the eyes, nose, and mouth. Observers also rated facial and nasal attractiveness using a 10-point visual analog scale. Gaze metrics were analyzed in relation to attractiveness ratings and anthropometric measurements.

[RESULTS] Models with unattractive noses received significantly more visual attention on the nose and mouth (total fixation duration (TFD): nose 0.81±0.14s vs. 0.72±0.12s, P =0.03; mouth 0.65±0.13s vs. 0.54±0.07s, P =0.03). Conversely, attractive noses permitted more visual attention on the eyes (TFD: 1.92±0.15s vs. 1.69±0.27s, P =0.02). Nasal tip deviation ( P =0.01) and longer upper lips ( P =0.05) correlated with lower attractiveness ratings, while traditional neoclassical canons and nasal width had limited impact ( P >0.05).

[CONCLUSION] Attractive noses enhance facial harmony by reducing visual attention on themselves, allowing gaze to focus on dominant features like the eyes. These findings highlight the importance of holistic facial assessments over isolated nasal evaluations during rhinoplasty consults. Future research should incorporate dynamic facial stimuli and diverse observer populations to further refine our understanding of nasal aesthetic perceptions.
