Investigation on Facial Skin Colour Perception Induced by Different Lipstick Shades

This study examines the colour assimilation effects of lipsticks on perceived facial skin tone among women, focusing on how various shades of lipstick alter skin colour perception and their association with attractiveness. Specifically, six different shades from Maybelline were applied to 10 female faces (5 Chinese and 5 Caucasian), and images were captured using a Canon DSLR camera in a controlled light booth equipped with D65 lighting. Fifteen Chinese female participants from Leeds were invited to view the images on a colour-calibrated display and use a scaling method to evaluate the perceived lightness, redness, yellowness, and attractiveness of the facial skin with each lipstick applied. The findings indicate that lipstick colours significantly influence the perceptual lightness and redness of facial skin, yet have a minimal impact on the yellowness of human faces. Meanwhile, Chinese observers showed slight different preferences for lipstick shades when judging the facial skin tone and attractiveness of Chinese and Caucasian faces – lipsticks with red tone, richer chroma and a higher delta E value are preferred for the Chinese group. Furthermore, significant correlations between perceived skin lightness, redness and perceptual attractiveness were revealed in this study. These results can provide support for makeup marketing strategies, help fashion professionals understand consumer behaviour, and guide individuals in selecting lipstick shades that align with their desired image.
