Visible skin condition and perception of human facial appearance / N. Samson in INTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Vol. 32, N° 3 (06/2010)
[article]
Titre : Visible skin condition and perception of human facial appearance Type de document : texte imprimé Auteurs : N. Samson, Auteur ; B. Fink, Auteur ; Paul J. Matts, Auteur Année de publication : 2010 Article en page(s) : p. 167-184 Note générale : Bibliogr Langues : Anglais (eng) Tags : Attractivité 'Perception du visage' 'Couleur de peau' 'Surface la Index. décimale : 668.5 Parfums et cosmétiques Résumé : La psychologie évolutive suggère que certaines normes de beauté de l'homme ont évolué pour fournir des indices fiables de la fécondité et la santé. Par conséquent, les préférences pour certaines caractéristiques physiques du visage et du corps sont censées refléter les adaptations pour la promotion de ce choix. Les études portant sur l'attractivité du visage se sont essentiellement concentrées sur des fonctionnalités telles que la symétrie, l'aspect d'ensemble et le sexe, éléments typiques développés dans le cadre de l'influence des stéroïdes sexuels. Mais peu d'études ont porté sur l'effet de l'état de la peau humaine sur la perception de l'apparence du visage, et ses implications possibles sur la sélection sexuelle. Il y a maintenant un faisceau de preuves montrant que la pigmentation de la peau et l'aspect de surface comme repères topographiques, notamment des femmes, ont une influence significative sur l'attractivité, car ils apparaissent comme des signaux de l'âge et de la santé. Cet article (i) passe brièvement en revue certains des déterminants principaux de l'état cutané visible, (ii) présente les dernières preuves de leur valeur de signalisation dans la perception du visage, et (iii) propose des domaines de recherche future comme référence-cadre de la psychologie évolutive.

Titre : Changes in facial impressions by controlling the color of surface reflection from cosmetic foundations: appearance evaluation and formulation technique Type de document : texte imprimé Auteurs : Koji Minami, Auteur ; Tomomichi Kaneko, Auteur ; Tomoyuki Suzawa, Auteur ; Taisuke Aosaki, Auteur ; Noboru Nagatani, Auteur ; Kimihiko Hori, Auteur Année de publication : 2007 Article en page(s) : p. 111-117 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Pigments pearlescent' 'Gonio-spectrophotomètre' Infographie 'Couleur glacée' 'Aspect du visage' 'Analyse factorielle' Index. décimale : 668.5 Parfums et cosmétiques Résumé : An attractive new series of foundations that vary in the glossy color originating in pearlescent pigments and are capable of changing facial impressions was developed. The color of the reflection of pearlescent pigments was attributed to additive mixing of interfering light. A brightly colored foundation film was obtained by mixing a sufficient amount of medium-sized pearlescent pigments into foundations. Five foundation films containing pearlescent pigments of different glossy colour (red, gold, green, blue and white) were prepared. Gonio-spectrophotometry was employed to determine the angle dependence of the reflected spectra, and the approximate optical characteristics of the films were derived. Using the approximations as input parameters in a made-up face simulation system, five images of a woman's facial skin with different glossy colors were processed by a computer graphics technique. Thirty-nine women assessed the facial impressions for glossy color using a semantic differential method with 69 descriptive words. Results of the subsequent statistical analysis showed that different glossy colors provide different impressions of facial appearance.

Titre : Prototypes of facial attributes developed through image averaging techniques Type de document : texte imprimé Auteurs : S. S. Hawkins, Auteur ; D. I. Perrett, Auteur ; D. M. Burt, Auteur ; D. A. Rowland, Auteur ; I. Murahata, Auteur Année de publication : 1999 Article en page(s) : p. 159-165 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Attributs du visage' Forme Morphing Evaluation Index. décimale : 668.5 Parfums et cosmétiques Résumé : Image capture and quantification has proven useful in a variety of scientific applications, for example, biology, medicine, geology, meteorology and forensics. The objective of this research was to utilize this technology to quantify clinical- and consumer-perceivable changes in facial attributes. A panel of expert assessors was trained, and, in a large consumer study, consumer facial attributes were identified and grading scales for each attribute were established. These experts then rated over 240 subjects on a total of 19 different facial attributes. Based on methodology developed by Perrett et al., facial averages or prototypes were computed from panelists rated high or low for each attribute. Prototypes were developed in a 3 step process: 1) selection of 224 predefined feature points; 2) calculation of average face shape; and 3) ’morphing’ individual faces into that shape and blending the images together. Naive assessors could readily appreciate the differences in facial appearance of the prototypes. In addition, expert graders were able to identify the general class of attribute affected. This method provides a powerful tool for assessing the effects of skin care technologies.

Titre : Scientific characterization of subclinical skin changes by noninvasive biophysical methods for development of more efficacious skincare products Type de document : texte imprimé Auteurs : Hachiro Tagami, Auteur Année de publication : 2007 Article en page(s) : p. 15-25 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Cornéothérapie 'Peau sèche' du visage' Hydratation 'Dermatoses subcliniques' 'Stratum corneum' Caractérisation Index. décimale : 668.5 Parfums et cosmétiques Résumé : In 1966, after finishing only my first year of a residency program, I went to the US to study for 2.5 years with Dr Albert M. Kligman the analysis of functional properties of various skin changes in vivo using aged skin, various types of dermatitis and topically applied steroid-induced atrophy as experimental models. Ten years later, I luckily found that measurements of high frequency conductance and capacitance of the skin enable us to evaluate the skin surface hydration state that determines the softness and smoothness of the skin and in particular to detect even subtle skin changes induced by changes in our environmental or by the application of skincare products and cosmetics. Employing such noninvasive biophysical instruments, I have analyzed the functional properties of normal and abnormal skin changes including subclinical skin changes such as atopic xerosis, senile xerosis, scars and effects of various topical and systemic agents. From these studies it became apparent that as long as a certain level of barrier function was retained skin surface hydration is a more important factor for enjoying a good quality of life. We also succeeded in confirming the effect of corneotherapy, the term so pertinently suggested by Dr Kligman for the beneficial effects of skincare products. We could show that their daily application definitely improves the condition of subclinical skin problems. Further progress in such instrumental analysis of skin properties will greatly aid us in the future in selecting a more desirable skincare product on an individual basis.
