Carotenoid skin colouration enhances face and body attractiveness: A cross-cultural study

Abstract

Previous research has indicated that faces with higher levels of skin carotenoid colouration are perceived as healthier and more attractive. However, it is not known whether this preference is specific to faces or reflects a more generalised preference in biological stimuli: for example, non-face body parts. Moreover, it is not yet well established whether the preference for carotenoid colouration extends beyond Caucasian populations. Three studies were conducted to address these issues. In Studies 1 and 2, Caucasian and Hong Kong Chinese participants, respectively, selected the more attractive image in pairs of high and low carotenoid colouration versions of images of Caucasian faces and body parts, and also for non-face/body-part control stimuli (scrambled faces). In Study 3, a similar study protocol was used with an independent sample of Hong Kong Chinese participants using stimuli generated from Chinese individuals. The results showed that high carotenoid colouration was preferred across all the three studies in faces and body parts, but not in the control stimuli. In addition, there was a stronger preference for high carotenoid colouration in faces compared with body parts in Studies 1 and 2—although this preference was not observed in Study 3. Overall, these findings demonstrate that higher levels of skin carotenoid colouration are preferred both in face and body parts, but not in non-face stimuli, and that these preferences are evident in Caucasian and Hong Kong Chinese individuals.

“…The effect of skin tone on attractiveness was also studied by Hill (2002) who found skin tone influences the attractiveness ratings assigned to black women in a compelling, monotonic manner—the fairer the tone the more attractive. Similarly, Ip et al (2019) further showed that, for Caucasian and Chinese participants, higher levels of skin carotenoid coloration (reddishness) were preferred in face and body parts, but not in non-face (scrambled pattern) stimuli. While Coetzee et al (2014) found some support for cross-cultural agreement, but also, that south-African participants relied more on skin color, and Scottish participants more on face shape features.…”

Women’s strategic use of clothing and make-up

“…Products that enhance skin tone (e.g. foundation, concealer, loose powder, bronzer and highlighter) tap into the skin being an ornament display (Zahavi, 1975) signalling health/immune status (Stephen et al, 2009) and reproductive condition (Stephen et al, 2011;Ip et al, 2019). Youth and fertility are also signalled by large lips (Gunn et al, 2009) and eyes ( Jones et al, 1995) and women have been using cosmetics to enhance the appearance of these areas since ancient times (Gunn, 1973).…”

“…However, cultural differences exist even for rather basic visual properties such as colour preferences (e.g. [40][41][42]), and the cultural context can interact with differences such as gender identity to shape which aspects contribute to an individual's preferences when evaluating faces (e.g. [43]).…”
