Titre : The age dependant changes in skin condition in japanese females living in northern versus southern japan Type de document : texte imprimé Auteurs : Greg. G. Hillebrand, Auteur ; Beverly Schnell, Auteur ; K. Miyamoto, Auteur ; Masamitsu Ichihashi, Auteur ; Reiko Shinkura, Auteur ; Suminori Akiba, Auteur Année de publication : 2001 Article en page(s) : p. 89-96 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Skin Wrinkling Hyperpigmentation Photodamage 'Ultraviolet radiation' Sebum Hydration Imaging Epidemiology Index. décimale : 668.5 Parfums et cosmétiques Résumé : Image analysis and biophysical methods were used to compare the skin condition of a group of females ranging in age from 5-65 years who had lived all of their lives in either Kagoshima prefecture (n=300), located in southern Japan, or Akita prefecture (n=302), located in northern Japan. Compared to Japanese women living in Akita, Japanese women living in Kagoshima had significantly longer facial wrinkles, higher number of wrinkles, larger hyperpigmented spots, higher number of spots, rougher facial skin texture, more yellow foreheads and upper inner arms, darker foreheads, and less stratum corneum hydration in the cheeks and arms. When compared on an age-for-age basis, the average 40 year-old Kagoshima women has the same level of facial wrinkling as a 48 year-old Akita women, an acceleration of 8 years for living in the more sunexposed southern latitude. For facial hyperpigmentation, the increase in onset is 16 years; the average 40 year-old Kagoshima women has the same level of facial hyperpigmentation as a 56 year-old Akita women. The results further testify to the skin damaging effects of sun exposure and may be useful in public health education to promote everyday sun protection.

Recent scientific advances in the understanding of the mechanisms of hyper- and hypo-melanogenesis in animal and human skin have been contributing to the development of novel topical whitening agents as cosmetics. The same applies for the systemic use of drugs and supplements that are expected to regulate melanin synthesis via up-and down-regulation of mRNA of enzymes and oter factors involved, and/or modulating the function of enzymes pivotal in melanogenesis.
In this review, we describe the mechanisms of melanogenesis in relevance to melanosomes, and their transportation and transfer from melanocytes to keratinocytes based on the recent evidence. Further, a role of alphamelanocyte stimulating hormone (α-MSH) and reactive oxygen species (ROS) in UV-melanogenesis is explained focusing on intracellular signal transduction. Finally, future strategy to develop lightening agents for the pigmented skin is discussed, in addition to the introduction of whitening agents previously developed in Japan.Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=10545
