This study investigated the relationship between facial youthfulness and facial areas. The cognitive model reported previously shows that youthfulness is a complex impression composed of estimated age, lively impression, and clean impression. Eight participants rated these impressions of seven facial images using Scheffe’s paired comparison method. The images consisted of an average face of 19 women in their 50s and modified average faces by adding moderate or severe wrinkles on the forehead, under the eyes, or around the mouth of the average face. Additionally, eye-movements were monitored during the rating of the average face. These investigations revealed that youthfulness and estimated age related to forehead and under-eye areas, whereas lively impression and clean impression related to under-eye area. Further analysis suggested that youthfulness had a combined feature of other three impressions. These results support the cognitive model of youthfulness reported previously and demonstrate that important facial areas vary with impressions.
