Stress -- Effets physiologiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Wellbeing is a pleasant state resulting from the satisfaction needs of the body and the calmness of the mind. Ultimately, a healthy mind and body are seen as the way to reach wellbeing and happiness. People aim to find a better balance of life, adopting wellness activities. This has translated into a strong consumer demand in many markets — ranging from healthy and organic food to alternative medicine, beauty care to detox, sports activities to mindfulness, green tourism to a healthy home. Consumers are looking for alternatives in line with a more sustainable and ethical way of life. Pure and natural products are top of the shopping lists in all fields.

Soins de beauté masculinsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Shaving means stress to the skin and a good aftershave will cairn and soothe the skin by reducing skin irritation and restoring moisture. Creating such a product that also responds to major trends in the personal care market such as being alcohol-free and composed of ingredients from natural origin is a real challenge. Here, we present an aftershave balsam with a natural formula containing potassium lactate and with proven anti-irritant and moisturising properties. Both chromameter and Corneometer® data from skin treated with the balsam showed significant improvements in skin redness and hydration level, but also the sensory perception of the product was convincing. Therefore, potassium lactate can be considered as a genuine natural alternative to conventional functional ingredients in aftershaves. Note de contenu : - Methods

Système de classementIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - OBJECTIVE : These were two folds: at first, to develop an automatic grading system specifically dedicated to some facial signs of men, similar to the one previously validated on women of different ethnic ancestry and second, to assess its potential in detecting and grading the possible impacts of a severe aerial urban pollution on some facial signs of Chinese men.
- METHODS : In both studies, selfie images were obtained from differently aged men. Nine facial signs were automatically graded through a specific A.I-based algorithm and clinically assessed by a panel of experts and dermatologists. Selfie pictures were taken from individual smartphones of variable optical properties. The first study, designed for developing an automatic grading system, involved three comparable cohorts of men from three different regional ancestries (African, Asian, Caucasian, 110 each) the selfie images of which were acquired under four different lighting conditions. As a second use case study, the facial signs of two cohorts of Chinese men (101 and 100, each), differently aged, regularly exposed to very different aerial urban pollution conditions (UP) were analysed by the same algorithm, selfies being taken under only one lighting condition.
- RESULTS :
- The new automatic grading system of facial signs suits well to men, showing comparable results than that the one dedicated to women and provides data in close agreement with experts’ assessments.
- In both cases (expert’s or automatic methodology), the accuracy of the scores appeared ethnic-dependent.
- The applied case confirmed previous results obtained clinically, that is, that many facial signs were found of an increased severity among men exposed to a severe urban pollution, as compared to those living in a less polluted city.
- In both studies, statistical agreements between the automatic grading system and expert’s assessments were reached. In some facial signs, the automatic grading system seems offering a slightly better accuracy than the assessments made by the experts.
- CONCLUSION : Apart from some minor limitations, this A.I-based automatic grading system, free from human intervention, performed as well as the one previously developed in women, in close agreement with expert’s assessments. In epidemiological studies, this system offers an easy, fast, affordable and confidential approach in the detection and quantification of male facial signs.Note de contenu : - MATERIALS AND METHODS : Subjects and conditions of provacy in the collection of smartphones selfie pictures (Study 1) - Facial signs analysed by automatic grading system (Studies 1 and 2) - Evaluation and grading of facial skinageing signs (Studies 1 and 2) - Principle of development of an automatic detection of facial signs from smartphone photographs (Study A) - Training and evaluation of the robustness of the automatic scoring system (Study 1) - Applied case on clinical impact of aerial urban pollution (UP in Chinese men (Study 2) - Statistics (Studies 1 and 2)

RéflectanceIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Multifactoriel, l'éclat du teint résulte de plusieurs composantes :
- La réflexion de la lumière, dépendante de la régularité du relief cutané, de la finesse du grain de peau et du taux de sébum,
- La couleur de la peau, liée quant à elle à la pigmentation et à la vascularisation
- Signe physique perçu au premier coup d'oeil, le teint est souvent le reflet d'un état général tant physique que psychique. Il peut traduire un état émotionnel, nutritionnel, ou encore révéler la fatigue, le stress, le tabagisme... Un teint éclatant sera synonyme de bonne santé, d'équilibre et de bien être.
S'agissant donc d'une revendication aux causes biologiques et physiologiques multiples, mais essentiellement liée à une perception visuelle, l'objectivation de l'éclat du teint se fait uniquement in vivo. Plusieurs méthodes sont ensuite disponibles pour l'évaluer et mesurer ses différentes composantes (couleur, texture, luminosité...).Note de contenu : - L'autoévaluation et le scorage

Tabac -- Effets physiologiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The oxidative effects of cigarette smoke on the human skin were investigated. A remarkable increase in the conversion ratio of squalene (SQ) to squalene monohydroperoxide (SQHPO) due to exposure to cigarette smoke was observed using a CL-HPLC (high performance liquid chromatography with a chemiluminescence detector) system. The results showed that cigarette smoke caused lipid peroxidation. We also found that the addition of chain-breaking-type antioxidants, such as oolong tea extract, inhibited the peroxidation. When cultured human skin fibroblasts were exposed to cigarette smoke, this increased the intensity of ultraweak chemiluminescence (CL), leading us to assume that cigarette smoke caused oxidation in cultured human skin fibroblasts. When the cultured human skin fibroblasts were treated with antioxidants such as glutathione, thiotaurine, hypotaurine and ascorbic acid there was little increase in CL, meaning that oxidation had been prevented in the human skin fibroblasts. We also exposed the human forearm to cigarette smoke and obtained sebum using cotton immersed in acetone in order to measure hydroperoxide levels by means of a CL-HPLC system. The exposure of skin to the smoke caused a dose-dependent increase in hydroperoxides derived from cigarette smoke. Further exposure of the forearm to cigarette smoke increased the intensity of CL, but pretreating the skin with antioxidants such as glutathione, thiotaurine and hypotaurine inhibited this increase. From these results, we concluded that cigarette smoke had an oxidative effect on SQ, cultured human skin fibroblasts and the surface of the human skin. The application of antioxidants prevented the cigarette smoke-induced oxidation. We consider that these oxidative effects on the skin could be a cause of skin disorders and skin aging.
