Stress oxydatifIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Epidermal stem cells (ESC) are necessary for epidermis renewing. These cells are also known to be more or less resistant to different types of apoptosis, in comparison with their keratinocyte counterparts: UV-induced cell death,1 oxidative stress-induced apoptosis2 or anoïkosis (a particular apoptosis resulting from loss of adhesion to extracellular matrix).
Thus, some models have been developed to extract ESC from epidermis, to culture them and to investigate their specific functions such as colony-forming capacity or their sensitivity to oxidative stress.2 Survivin, an anti-apoptotic protein, has been shown to be specifically expressed in the nucleus of ESC, among an extracted population composed of ESC, transitoryamplifying cells and differentiated keratinocytes.4 ?Np63 is a p53 antiapoptotic homologue which has also been shown to be specifically expressed by ESC.5 It has been described to give UVB resistance to ESC and to decrease in these cells after such a stress.6 The NGF-pathway has also been shown to be implicated in this resistance, inducing an increase in the production of the antiapoptotic Bcl-2 molecule.1,7 Other ESCassociated markers have been described, such as MCSP (Melanoma Chondroitin Sulfate Proteoglycan)8,9 or a high level of ?1-integrin expression.3 The purpose of this study was, first, to develop new in vitro models to investigate ESC response after these different types of stresses and, second, to investigate the preventive effect of active ingredients. We particularly focused on cocoyl alanine (CA), an antioxidant and anti-wrinkle cosmetic product. Indeed, previously obtained results suggested that it was able to protect elderly skin explants from ex vivo culture-induced decrease in survivin expression (nuclear form) within epidermis.Note de contenu : - METHODOLOGY : Reagents and materials - ESC extraction and culture - Investigation of ESC phenotype by immunofluorescence - Investigation of ESC resistance to UVB - Investigation of oxidative stress on ESC culture apoptosis - Investigation of UVB on ESC ΔNp63 level and apoptosis

Taille des poresIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Skin is a living organ with ever-changing and sometimes conflicting needs. To meet the expectations of today's consumers, skin care products must harness the skin's own synergies, responding flexibly to daily changes in skin condition. Dual action products offer a host of options to meet these expectations, but the duality claim must be logical, credible and scientifically substantiated. At the same time, the demand for natural, ethically sourced and environmentally friendly ingredients is growing.
Inspired by fermented Asian food DSM's Beauactive® is a naturally derived, highly pure, potent hydroxystearic acid that provides two distinct benefits : it visibly reduces both conspicuous facial pores and age spots. Furthermore, it fulfills both DSM's high standards on sustainability and the principles of Green Chemistry and embraces the latest trend for transformational beauty products, combining science with a fun, new sensory experience for consumers.Note de contenu : - What consumers want: products that do more

Sécheresse cutanéeUne xérose est un dessèchement de la peau.
Elle peut avoir différentes causes, comme certaines pathologies (dermatite atopique aussi appelé eczéma atopique), des carences, notamment en Vitamine A, ou des facteurs externes, comme les contacts avec des substances irritantes ou le traitement par certains médicaments.Tags : 'Peau sèche et rugueuse' 'Activateur de plasminogène' 't-AMCHA' 'Fonction barrière' 'Physiologie la peau acné/boutons' Index. décimale : 668.5 Parfums et cosmétiques Résumé : The prevention and improvement of « rough and dry skin » occupies a key position in the basic function of skin care cosmetics. Therefore, research on skin physiology and the development of active ingredients for products for the treatment of rough and dry skin conditions are important and universal topics.
With the purpose of clarifying the role of internal factors in the process of dry skin occurs, we investigated from a pharmacological perspective as a new experimental strategy. Through this research, we have conceived a new theory explaining how dry skin occurs. Furthermore, on the basis of this theory, we have developed a new effective compound for its treatment.
In order to study on the mechanism by which dry skin occurs, we used anti-inflammatory agents and inhibitors against histological impairment mediators, as well as various substances that were considered to regulate the function of epidermal cells. The results showed that protease inhibitors, especially the plasminogen (PLG) activation system-specific inhibitors, were effective against dry skin caused by extrinsic factor. Furthermore, its effects closely correlated with the inhibition activity against the PLG activation system. In addition, we demonstrated immunohistologically that the PLG activation system, which was only located along the epidermal basal layer of normal skin, was widely distributed throughout all layers of epidermis while dry skin induction. These results strongly suggested that the occurrence of dry skin involves a cause bringing about the over-manifestation of the epidermal PLG activation system, which in turn causes abnormalities in the regulating mechanisms for the proliferation and differentiation of epidermal cells, and these result in dry skin.
We discovered trans-4-aminomethylcyclohexanecarboxylic acid (t-AMCHA), which was the most effective substance in view of the theory on the occurrence of dry skin. Then we investigated in detail the efficacy of t-AMCHA. The results of our studies confirmed that t-AMCHA strongly suppresses the over-manifestation of the PLG activation system in the epidermis when dry skin was occurring. In addition, t-AMCHA demonstrated superb effectiveness against phenomena caused by dry skin, including the loss of moisture from the horny layer, the increase in transepidermal water loss (TEWL), accelerated turnover in the horny layer, and the changes in various other indicators such as epidermal hypertrophy. These results strongly supported the effectiveness of t-AMCHA on dry skin.
Based on these research findings, we have further developed a novel active ingredient, t-AMCHA, which is being widely applied to skin care products.
Furthermore, subsequent research on the efficacy of t-AMCHA has confirmed this compound to be effective in promoting restoration and recovery of the barrier function of the stratum corneum, which is a key role of the horny layer.
We have also conducted research on the skin physiology of acne and/or pimples of the pilosebaceus unit, which are the main skin problem for Japanese females in their 20s and 30s. Examination of the skin condition of females who are prone to develop these problems demonstrates a relative lowering of several physiological functions of the horny layer. These results indicate the necessity of incorporating new skin care technology designed to targets improvement on the horny layer function.
With the background, we focused on the effectiveness of t-AMCHA in improving functions of the horny layer and developed new products by incorporating rough rough skin control technology into conventional and basic counter-acne techniques. In-use studies of these products showed favorable results.
Through the application in anti-acne products, research and development of counter rough skin technology as a basic function of skin care products is being extend beyond the category of cosmetic products.Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=10641
