Langues : Anglais (eng) Catégories : Actifs anti-pollution Cosmétiques Ectoine Peau -- Effets de la lumière Peau -- Soins et hygiène Index. décimale : 668.5 Parfums et cosmétiques Résumé : Due to its global skin protection and regenerating efficacy, the extremolyte ectoine became a well-established active ingredient in the part years. Its unique and global anti-pollution activity has been demonstrated in vivo by analysis of barrier lipid oxidisation levels from the skin surface as well as in human lungs, where ectoine reduces inflammations induced by pollution particles. Ectoine's visible light protection property results in the reduction of the cell's oxidative stress response to visible light irradiation and the prevention of hyperpigmentation. In addition, the natural amino acid derivate regenerates environmentally irritated skin including the skin barrier function due to its strong anti-inflammatory benefits. In conclusion, ectoine is a multifunctional and safe active ingredient with clinically proven efficacy - very well-suited for cosmetic formulations, which need to match various consumer demands and market trends.

Natural molecule offering anti-pollution benefits / Janina Kienemund in GLOBAL PERSONAL CARE, Vol. 23, N° 10 (11/2022)  

[article]  inGLOBAL PERSONAL CARE > Vol. 23, N° 10 (11/2022) . - p. 25-28 Titre : Natural molecule offering anti-pollution benefits Type de document : texte imprimé Auteurs : Janina Kienemund, Auteur ; Eva Galik, Auteur ; René Schmitz, Auteur Année de publication : 2022 Article en page(s) : p. 25-28 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Actifs anti-pollution Agents de blanchiment Barrière cutanée Dermo-cosmétologie Ectoine Ingrédients cosmétiques Lumière bleue Peau -- Soins et hygiène Protection cutanée Index. décimale : 668.5 Parfums et cosmétiques Résumé : German active ingredient supplier bitop explains why the natural extremolyte Ectoin is suited for cosmetic formulations for all skin types, matching various consumer demands and market trends such as anti-pollution, blue light protection and whitening. Human skin is situated at the interface of the organism and its environment and is therefore constantly exposed to numerous extrinsic stress factors. Chronic exposure to environmental conditions, including ultraviolet light (UV), blue light and air pollution has been shown to have a significant impact to skin health and ageing. It is an indisputable fact that cutaneous ageing is mainly driven by external stress factors, promoting the formation of reactive oxygen species (ROS), encouraging inflammation processes in tissues and cells and compromising the natural skin barrier. This results in an increase of trans-epidermal water loss (TEWL), along with a decrease of skin thickness, skin elasticity and the occurrence of wrinkles and pigment spots. Additionally, dermatoses like rash, eczema, allergies, psoriasis and atopic dermatitis are caused or exacerbated by external influences. Protecting the skin from external stress-factors and the prevention of cell damage thus are logical and effective strategies to slow down premature skin ageing and treat disease affected skin. In recent years, stress-protection molecules, so-called extremolytes, have become popular as cosmetic active ingredients, e.g. bitop Ectoin® natural (hereafter referred to by its INCI name, Ectoin).

Study data confirm global antipollution activity / Silke Schagen in PERSONAL CARE EUROPE, Vol. 11, N° 2 (04/2017)  

[article]  inPERSONAL CARE EUROPE > Vol. 11, N° 2 (04/2017) . - p. 126-128 Titre : Study data confirm global antipollution activity Type de document : texte imprimé Auteurs : Silke Schagen, Auteur ; Sabrina Overhagen, Auteur ; Susanne Grether-Beck, Auteur ; Jean Krutmann, Auteur ; Andreas Bilstein, Auteur ; Eva Galik, Auteur Année de publication : 2017 Article en page(s) : p. 126-128 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Anti-inflammatoires Biomolécules actives Peau -- Effets de la pollution atmosphérique Peau -- Soins et hygiène Protection cutanée Index. décimale : 668.5 Parfums et cosmétiques Résumé : Latest scientific evidence confirms, that air pollution contributes to premature skin ageing and may even be the primary cause of ageing in some cases. Especially for particulate matter and polycyclic aromatic hydrocarbons (PAHs) negative influence on skin integrity has been shown. The natural stress-protection molecule Ectoin® is well known to strengthen the skin barrier function, to work against variable stressors such as UVA/UVB radiation, IR-A, visible light or allergens, and for its anti-inflammatory activity. This study demonstrates the global protection and prevention efficacy of Ectoin from air pollution induced skin damage. Ectoin is well suited for topical antipollution products targeting skin pigmentation and accelerated ageing as well as particle stressed and irritated skin. Note de contenu : - FIGURES : Pollution particles to induce POMC expression in keratinocytes - Pollution particles to induce MMP1 expression in keratinocytes - Pollution particles to induce Cyp1A1 expression in keratinocytes - Up-regulation of A) POMC, B) NMP1 ane C) Cym 1A1 mRNA expression in primary human keratinocytes (Asian and Caucasian) by sub-toxic amounts of ultrafine and fine carbon black particles and by two different types of exhaust particulates. 18S ribosomal RNA (rRNA) was used as a POMC overexpression. The remaining response is calculated by setting the pollution induced effect equal 100% B, C) Ectoin reduces MMP1 and Cyp 1A1 up-regulation and protects keratinocytes also from fine carbon black particle and diesel particulate matter - 2. In vivo study design, smoke application with standardised chamber system - 3. Cigarette smoke application on the volar forearm - after only 5 days of application with 1% Ectoin the pollution induced MDA content in the skin was reduced by 48% compared to the placebo treated areas. A strong anti-oxidant (gold standard) was able to reduce the pollution-induced MDA content in the skin by 27% (data not shown) En ligne : https://drive.google.com/file/d/1pyp0JC-G2uNE-LMat0KXsvfe-b7nMp5D/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=28350 [article]
