Titre : Does asian skin induce significant changes in sun protection factor (SPF) determination comparde to caucasian skin : one of the first in-vivo correlations Type de document : texte imprimé Auteurs : E. Camel, Auteur ; Lynda Aranaud-Boissel, Auteur ; S Schnebert, Auteur ; Michèle Neveu, Auteur ; S. K. Tan, Auteur ; Jean-Pierre Guillot, Auteur Année de publication : 2002 Article en page(s) : p. 31-34 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Asian skin' Caucasian 'Skin color' Ethnic differences' MED SPF Index. décimale : 668.5 Parfums et cosmétiques Résumé : The aim of this study was compare the SPF of three sunscreens (SPF 6/8-15/20-25/30) and 2 standars ( FDA,COLIPA fla P2), according to COLIPA recommendations, in panels of Asian (Singapore) and Caucasian (France) volunteers. Sixty male and female groups panelists were included in the test: two groups of Asians, defined according their color typology (as measured with a Chromameter: I.T.A.°:28-41° or 41-60°), and one group of Caucasians (I.T.A.°: 41-60°) in order to make a possible correlation with the light colored Asians.
Results showed statistically significantly higher SPF in the lighter Asian skin group (I.T.A.°:41-60°) compared to the Caucasian group with similar skin color for the sunscreens with SPF 15 and 30,whereas no significant difference was observed for FDA and COLIPA standards, not for the SPF 6/8 sunscreen.
These results show that differences in SPF between Asian and Caucasian skin exist.These differences are clearly present for the high SPF sunscreens and might not be only explained by skin color but also by other internal or external factors affecting skin response to UV.Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=10673

Titre : The age-dependent changes in skin condition in african americans, asian indians, caucasians, east asians, and latinos Type de document : texte imprimé Auteurs : Greg. G. Hillebrand, Auteur ; Mark. J. Levine, Auteur ; K. Miyamoto, Auteur Année de publication : 2001 Article en page(s) : p. 259-266 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Skin 'Racial differences' Aging Imaging Epidemiology Index. décimale : 668.5 Parfums et cosmétiques Résumé : Understanding the similarities and differences in skin characteristics as a function of age, race and geography should aid in the development of skin care products that better meet consumers’ skin care needs around the world. Several studies have compared various racial groups for specific skin parameters. This study is unique for its inclusion of live different racial/ethnic groups (African American, East Asian, Caucasian, Indian Asian, and Latino), its large base size (3160 subjects), its wide age range (10-70 years), and the breadth of skin parameters measured (both visible features and biophysical characteristics). Using the same image collection system in all geographies [London, Los Angeles, Rome, Akita (Japan)], high-resolution digital images of the subjects’ faces were collected under controlled conditions and computer analyzed to objectively quantify the amount of facial skin wrinkling, hyperpigmentation and pores. Biophysical skin parameters measured included: skin color (L*a*b) on the forehead and upper inner arm; sebum secretion rate on the forehead stratum corneum capacitance on the cheek, forearm and calf; skin surface pH on the cheek, forearm, and calf and surface flakes on the calf. In addition, all subjects completed a structured questionnaire to gather information on host and environmental factors such as body weight, smoking history, menopausal status, etc. Descriptive statistical analysis of the objectively measured skin parameters as well as an analysis of the host and environmental factors significantly associated with these skin parameters are presented.
