SéborrhéeIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Performed tests approached pollution in different mechanisms and showed consistent protective efficacy of Acrochaetium moniiiforme extract:
• Epidermal tells protection from cadmium
• Sebaceous gland protection from urban dust
• Skin protection from ozone
In vitro data on cadmium-stressed keratinocytes showed an interesting protection capacity of Acrochaetium moniliforme extraction on the epidermal mechanical barder, botte protecting directly the cell integrity and downregulating the induction of an inflammatory state.
in vitro data on a new specifically designed protocol based on the use of human sebocyte cell line, showed that these cells are highly stimulated by urban dust and react by overproducing lipids. These new insights suggest the existence of a specific biological mechanism in oily skin : reactive sebum due to polluted environment. Acrochaetium moniliforme extract was specifically able to reduce this impact.
Finally in vivo data, obtained in a study conducted in an urban polluted environment (Shanghai), confirmed the efficacy of Acrochaetium moniliforme extract, decreasing sebum production and decreasing direct pollution impact on skin (ozonolysed squalene).
Thus, through this global protective effect (Fig 6), Acrochaetium moniliforme extract can be proposed as an urban life dermopurifying ingredient in ail kinds of formulation with anti-pollution daims. Thanks to this unique macroalgae tell technology, Seppic is able to create value from this unexplored marine resource and offer it to its customer to get rid of oily skin for long term benefits.Note de contenu : - Halting urban pollution's impact on skin
