Microbiote cutané -- AnalyseIndex. décimale : 668.5 Parfums et cosmétiques Résumé : BASF explores two new biotic active ingredients derived from the Lactobacillus crispatus bacterium.
Care products with biotic ingredients have gained enormous popularity since they are known for improving health and wellness and are associated with eco-friendliness. More specifically, consumers are seeking products that naturally target the biological ageing process of the skin. Two new biotic active ingredients derived from the Lactobacillus crispatus (LC) bacterium are supporting cosmetics manufacturers in successfully responding to this trend.Note de contenu : - Lactobacillus crispatus : a youth bacterium

VieillissementIndex. décimale : 668.5 Parfums et cosmétiques Résumé : With Lys'IastineTM V, we present an anti-ageing active that targets the cellular senescence of fibroblasts. In vitro, 0.025% Lys'lastine V significantly reduced the accumulation of progerin, the "ageing protein" that is linked to replicative senescence in fibroblasts (-54 %). Furthermore, 0.05 % Lys'lastine V significantly increased levels of the "youth protein" Klotho (+34%), while 1 % Lyslastine V re-induced expression of lysyl oxidase-like (LOXL) in reconstructed dermis (MimedermTM) (+64%) and increased levels of LOXL in a reconstructed skin model (MimeskinTm). LOXL is the cross-Iinking agent responsible for the deposit of tropoelastin on microfibrils and therefore the synthesis of functional elastic fibers in the dermis — but from the age of 18, it decreases rapidly. By re-inducing LOXL, this BASF active helps restore the skin's elasticity, ln a clinical study, Lys'lastine V was proven to significantly improve the skin's suppleness, both on the face and décolleté.

Pseudomonas aeruginosaIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Bacteria use a cell-to-cell communication system called quorum sensing (QS) to share information about cell density and adjust gene expression accordingly. This article explains BASF studies into how natural plant extracts are able to quench QS signals from P. aeruginosa and S. aureus. Then, it checked if their effect on QS was followed by a decrease in virulence, determined by both bacteria motility and lipase secretion. Note de contenu : - MATERIALS : Molecules - Equipment

PolyphénolsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : From a centuries-old superfood to a "magic" ingredient : BASF's latest bioactive Inolixirâ„¢, a 100% natural extract of the chaga mushroom native to Canadian birch forests, pro-motes skin health with fast and long-lasting efficacy for tired and sensitive skin. That's the feedback from trial participants – and various in vitro and in vivo studies have confirmed its efficacy. By fortifying the skin's protection system and reducing pro-inflammatory response, it delivers visible results on fine lines and dark circles, as well as skin dullness, redness and comfort. A special extraction method is key to harnessing the mushroom’s power. Note de contenu : - Subcritical water extraction
- A strengthened skin barrier with well-protected vessels
- A spa experience for tired skin
- A wave of radiance and comfort for sensitive skin prone to redness
