Peau -- Soins et hygièneIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Skin-thinning in aged skin is considered an important factor in the formation of wrinkles. Due to natural ageing of the epidermal keratinocytes, there is a remarkable production of senescenceassociated secretory phenotype (SASP) factor, which induces matrix metalloproteinase-1 production in dermal fibroblasts, resulting in dermal thinning. Meanwhile, extracellular ATP (eATP) is known to induce the production of SASP factors, but the relationship between eATP and natural ageing is unknown. In this study, we showed the relationship between the increase of eATP in the epidermis and the dermal thinning seen with natural ageing. Peppermint leaf extract (PME) effectively suppressed the rise in eATP concentration due to natural ageing and environmental stress. Furthermore, PME suppressed skin thinning and improved various wrinkles, such as crow’s feet and neck wrinkles. These results suggest that PME is an antiageing material that suppresses eATPmediated dermal thinning and effectively improves wrinkles in many areas. Note de contenu : - Testing PME

Produits antisolairesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Une exposition excessive à la lumière du soleil, en particulier aux rayons UV, peut nuire à la santé de plusieurs façons. A court terme, par une réaction inflammatoire de la peau communément appelée coup de soleil. A long terme, par un risque majeur de vieillissement prématuré et de cancer de la peau. Le but de cette étude sera de présenter un ingrédient actif naturel issu de la science innovante et qui permettra d'améliorer la performance des produits de protection solaire.

Vieillissement cutané -- PréventionIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Environmental pollution now-a-days is considered one of the main causes of skin ageing. Among the pollutants, tobacco smoke and PM2.5 (particulate matter) are thought to be the major health hazardous components responsible for skin in-flammation, pigmentation, and wrinkling, as evident from sporadic clinical and epidemiological studies. Our objective was to develop a plant-based natural ingredient that could suppress the detrimental effects of those two pro-minent pollutants on human skin tells. Normal human epidermal keratinocytes (NHEK) and normal human dermal fibroblasts (NHDF) were exposed to PM2.5 and tobacco smoke, respectively, for the induction of inflammation and collagenase activity. Various plant extracts were screened for their efficacy in showing anti-ageing properties against these pollutants. We showed that our unique extract, Ougon, was able to suppress the tobacco smoke-induced expression of matrix metalloproteinase-1 (an enzyme responsible for the degradation of extracellular matrix) in NHDF by inhibiting the expression of CYP1B1 (a member of the cytochrome p450 family). Moreover, Ougon was found to have strong efficacy in inhibiting the PM2.5-induced expression of some inflammatory mediators (e.g. IL-113, IL-6, and IL-8) in NHEK in concentration-dependent manners. Therefore, we suggest that Ougon extract may protect the MMP-1 and inflammation-mediated ageing of skin induced by environmental stress factors.

Tabac -- Effets physiologiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : For the last 20-30 years UV was really the main topic in skin care science. Until recently, people might not have been aware of the detrimentaI effects of environmental pollution on skin mainly because UV was thought to be the one to cause extrinsic skin ageing. Nowadays, people have come to know that pollutants have harmful affects similar to that of UV on skin, and also that pollutants in combination with UV may have greater impact on skin because of the production of ozone from photochemical reactions between the pollutants, heat, and UV. One of the pollutants is tobacco smoke, which is well-known for its harmful effects on health, and another is PM2.5, against which scientists have already declared war all over the world.
People are now looking for solutions to the harmful affects of pollution. We have been conducting exclusive research on environmental factor-induced skin ageing for many years. Among these factors we investigated tobacco smoke and PM2.5's relationship with skin ageing with the aim of developing a natural-based cosmetic ingredient to be used in cosmetic formulations. We could provide one optimistic solution that ougon extract could be an ideal cosmetic ingredient for manufacturers willing to develop an anti-ageing finished product based on skin care against environmental pollution, particularly tobacco smoke and PM2.5.Note de contenu : - AIR POLLUTION AND ITS MECHANISM OF ACTION
