According to the results of a recently published study, there is a correlation between the amount of collagen in mature skin and the microbial composition of the cutaneous microbiota. The skin, a multifunctional organ This is the most extensive and heaviest organ in the human body, acting as an interface between the internal and external environments. Made up of three layers (the epidermis, dermis, and hypodermis), it has essential functions such as : Sensoriality; Synthesis of molecules; And a barrier effect. Healthy skin is elastic, smooth and resistant. However, pollution, UV rays, poor diet and germs can make it more [...]
The intestinal microbiota has a central role in our health. We already know its unsuspected link with the brain and its impact on neurodegenerative diseases, stress, anxiety. However, the brain is not the only organ with which it works closely. Indeed, there is a new axis: the skin-gut axis. A Canadian research team has been working to prove this. The researchers observed whether UVB light had an impact on the gut microbiota composition. A clinical trial to prove the gut-skin axis A pilot study was conducted between February and April 2018 on 21 women with skin types ranging from I to [...]
Rebalance the skin microbiota by wearing probiotic clothes? It is now almost possible! Currently, it is still in the concept state. An idea from science The science shows that the cutaneous microbiota serves as a barrier against certain microorganisms, allergens and other toxins by limiting the infectious and pathological impact. Acne, eczema, rosacea, psoriasis… Skin conditions potentially caused or exacerbated by an imbalance between good and bad bacteria present on our skin. The hypothesis: the hygienist theory. In other words, inadvertent washing and disinfection causing dysbiosis. In addition, the cosmetic composition of used products and the wearing of certain clothes can [...]
In any case, this is what the US army wants to do in order to protect their soldiers. Darpa (Defense Advanced Research Projects Agency) has launched a new program, named ReVector, to find ways to reduce or even eliminate the risk of transmitting diseases caused by mosquitoes. Mosquitoes, these vectors of diseases Indeed, these insects (including Aedes, Anopheles and Culex) are vectors of potentially lethal diseases such as malaria, dengue fever, the Murray Valley or Japanese encephalitis. These pathologies represent a great threat for troops deployed abroad. A new approach to repel mosquitoes: modification of the cutaneous microbiota Why not just [...]
Summer is finally here! You spend your free time enjoying the sun and maybe even going to the beach. But do you know that swimming in the ocean can alter the skin microbiota? And in addition, can increase the infection risk? A team of researchers presented clinical results suggesting some interactions between our skin and the ocean at the annual meeting of the American Society for Microbiology. This clinical trial was motivated by previous studies showing a correlation between swimming at sea, water quality and the infection risk. Indeed, microbiota changes can cause skin, gastrointestinal, or ENT infections including respiratory or [...]
