- Materials and Methods : Standardized digital photographs were taken on 201 subjects from two cohorts of Chinese men (100 inhabitants of Baoding/very polluted and 101 inhabitants of Dalian/less polluted) differently aged (20–60 years) allowing a focus on 17 different facial signs. The latter were graded by 15 experts, using a clinical referential skin atlas. A questionnaire was filled by all subjects collecting their habits and uses with regard sun-exposures and skincare products. A naïve panel of 80 Chinese women, of comparable ages, attributed a perceived age to each subject under blind conditions.
- Results : These confirm previous data obtained on Chinese women, with a similar protocol, i.e. that some facial signs show an increased severity in the more polluted city. However, changes in facial signs, with age, are of a different pattern according to gender. In Chinese men, most signs show early onsets with however low age-related changes, inversely to those observed in women, at the exception of vascular disorders. Habits of sun-exposures and uses of skincare product were found totally similar in both cohorts, reinforcing the specific role of UP in the progressive changes of facial signs. Similar to the results previously obtained on Chinese women, men living in a more polluted city were judged older than those living in a less polluted aerial environment.
- Conclusion : The present work confirms that a more severe UP increases the severities of some facial signs in Chinese men.Note de contenu : - MATERIALS AND METHODS : Subjects - Cities,weather conditions - Protocol - Pictures acquisitions - Evaluation and grading of facial skin aging signs - Appraisals by a naïve panel (perceptions by 'the others') - Statistics

Signes du visageIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : To determine the respective weights of certain facial signs on the assessment of perceived age, tired-look and healthy glow on Chinese men of different ages.
- Material and methods : Photographs were taken of the faces of 420 Chinese men of different ages, under standardized conditions. These photographs allowed to focus and define 15 facial signs, which were then graded by 15 experts and dermatologists, using standardized scales provided by a reference Skin Aging Atlas. The facial signs were dispatched into 5 clusters, namely wrinkles/texture, ptosis/sagging, pigmentation disorders, vascular disorders and cheek skin pores. A naïve panel, composed of 80 Chinese women, of similar age range were asked, when viewing full-face photographs, to : (i) attribute on a 0–10 scale their perception of both the tired-look and healthy glow aspects and (ii) estimate the age of the subject.
- Results : With the exception of vascular disorders, the severity of all 4 clusters increased with age, although at different rates. The ptosis/sagging or pigmentation disorders showed a rather regular progression. Although perceived ages and real ages were found to be closely correlated, the vast majority of subjects were judged older by 2–10 years. The changes in facial signs (and their related clusters) were significantly correlated with perceived age, with the exceptions of skin spot density and cheek skin pores. Although the aspects of tired-look and healthy glow were logically found to be anti-correlated, tired-look was more statistically associated with perceived age for the five clusters. Signs of eye contour appear to be closely correlated with the perception of a tired-look.
- Conclusion : Within facial clinical clusters, wrinkles/texture and ptosis/sagging are major factors in the assessment of perceived age in Chinese men. Tired-look appears to be strongly associated with perceived age.Note de contenu : - MATERIALS AND METHODS : Subjects - Protocol - Pictures acquisitions - Grading the facial skin ageing signs - Appraisal by a native panel - Statistics

StatistiqueIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : Accuracy in assessing age from facial cues is important in social perception given reports of strong negative correlations between perceived age and assessments of health and attractiveness. In a multi-ethnic and multi-centre study, we previously documented similar patterns of female facial age assessments across ethnicities, influenced by gender and ethnicity of assessors.
- Methods : Here we extend these findings by examining differences between estimated age from digital portraits and chronological age (Δ age) for 180 women from three age groups (20–34, 35–49, 50–66 years) and five ethnicities (36 images of each ethnicity, assessed for age on a continuous scale by 120 female and male raters of each ethnicity).
- Results : Across ethnicities, Δ age was smallest in French assessors and largest in South African assessors. Numerically, French women were judged oldest and Chinese women youngest relative to chronological age. In younger women, Δ age was larger than in middle-aged and older women. This effect was particularly evident when considering the interaction of women's age with assessor gender and ethnicity, independently and together, on Δ age.
- Conclusion : Collectively, our findings suggest that accuracy in assessments of female age from digital portraits depends on the chronological age and ethnicity of the photographed women and the ethnicity and gender of the assessor. We discuss the findings concerning ethnic variation in skin pigmentation and visible signs of ageing and comment on implications for cosmetic science.Note de contenu : - Study sample

VisageIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : Facial attractiveness has been reported to be influenced by visual features such as facial shape and the colour and texture of the skin. However, no empirical studies have examined the effects of facial skin radiance on facial attractiveness. The present study investigated whether types of skin reflection (i.e. radiant, oily and shiny, and matte) and the position of the reflection on the face influence facial attractiveness and other affective impressions.
- Methods : A total of 160 female participants (1) estimated the ages and (2) evaluated attractiveness and other impressions of unfamiliar female faces in a total of seven skin reflection conditions. These conditions incorporated three types of reflection (i.e. radiant, oily and shiny, and matte) and three positions of the reflection on the face (i.e. entire facial skin, only cheeks, and only T-zone).
- Results : The facial images of radiance on entire faces were rated as appearing younger than the facial images of oily shine on entire faces and the matte faces. Attractiveness ratings and other positive impressions increased in the order of the matte (ranked lowest), the oily shine on entire face, and the radiance on entire face (ranked highest) conditions. The reflection position also influenced facial attractiveness: attractiveness ratings and other positive impressions were higher in the radiance on entire face condition than in the radiant cheeks and the radiant T-zone conditions. Interestingly, the radiant cheek faces were rated more radiant and healthier but less feminine and less bright than the radiant T-zone faces.
- Conclusion : These results suggest that facial radiance enhances facial attractiveness and conveys a wide variety of positive impressions on the observer. The magnitude of the effects of cheek radiance and T-zone radiance differs across various affective impressions. Nevertheless, the results demonstrate that cheek and the T-zone radiance both contribute to higher attractiveness and other positive impressions of the radiance on entire faces. We believe that our findings can contribute as a guide to the enhancement of positive facial impressions by means of skin radiance, thereby leading to a better understanding of the value of skincare and base makeup.Note de contenu : - METHODS : Participants - Apparatus - Facial stimuli - Photography phase - Tasks and procedures

Vieillissement cutanéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - OBJECTIF : Le désir d'apparaitre jeune constitue une motivation forte dans l'achat de produits cosmétiques par les femmes du monde entier. Afin de développer une solution anti-âge qui cible les besoins des consommateurs, il est clé de comprendre quels signes visibles de l'âge sont d'une importance primordiale et influencent la perception de l'âge. A ce jour, une population Russe n'a pas été l'objet d'une telle recherche. Le but de cette étude est d'identifier les signes cliniques de l'âge qui contribuent majoritairement à une apparence plus âgée ou plus jeune pour les femmes de plus de 40 ans.
- METHODES : L'âge de 203 sujets féminins Russes a été déterminé à partir de leur photographie standard par un total de 629 évaluatrices naïves âgées entre 20 et 65 ans. L'âge estimé a été évalué en relation à 23 signes visibles de la peau mesurés au préalable en utilisant les coefficients de corrélation linéaires. Les signes de l'âge, confirmés en corrélation avec l'âge estimé, ont été évalués de façon à mettre en évidence leur différence de valeur de sévérité moyenne entre les femmes perçues plus âgées et les femmes perçues plus jeunes que leur âge chronologique. Les volontaires ont préalablement répondu à une question visant à classer leurs signes de l'âge par ordre d'importance. Ces résultats ont été analysés afin de procurer la perspective du consommateur sur le vieillissement du visage.
- RESULTATS : Parmi les 23 signes de l'âge mesurés, neuf ont été identifiés avec une corrélation plus importante avec l'âge perçu. De tels résultats démontrent l'importance des rides de la partie supérieure du visage (pates d'oies, glabellaire, sous les yeux et du front), mais aussi des rides de la moitié inférieure du visage associées à l'affaissement facial (dessus de la lèvre supérieure, pli nasolabial). Cet affaissement du visage a été confirmé d'importance clef pour les volontaires âgés de 41 à 65 ans qui étaient principalement concernées par la ptose du contour de leur visage au-delà des rides sous les yeux et des rides du coin de l'œil. La sévérité des taches pigmentaires, rouges et brunes, a été aussi identifiée en tant que contributeur à l'estimation de l'âge, bien que plus faiblement.
- CONCLUSION : En procurant une vue claire sur les signes de l'âge qui sont d'importance primordiale pour les femmes Russes âgées de plus de 40 ans, cette étude offre une information critique pour le développement de solutions anti-âge pertinentes qui ciblent spécifiquement leurs besoins et notamment leur désir de conserver une apparence jeune.Note de contenu : - MATERIALS AND METHODS : Self-declared skin ageing concerns - Perceived age assessment - Statistical analysis
