Our invisible friends… the microbes!
August 10, 2020
Microbes used to have a very bad reputation as they were only known to be responsible for diseases. But we discovered since then that only the pathogen ones are “bad” and the others are actually primordial for our skin health, no matter if they are in our guts or on our skin.
Our bodies are populated by numerous communities of bacteria, fungi, viruses and other microorganisms, forming the human microbiota, also called microbiome, referring to an ecosystem (skin microbiome for instance).
The relationship between the skin and the microbiota is very complex, and difficult to study due to the variability of the microbiome:
From Belkaid et al. SCIENCE. 2014;Nov.
We realised the role of the skin microbiome when the development of personal cleansing increased the number of skin diseases, and we understood that reversing this dysbiosis may help prevent and/or treat the disease. 
The skin microbiome plays an essential role in the protection against invading pathogens, the education of our immune system and the breakdown of natural products.  It’s even considered as a fourth skin protective layer: the stratum microbium.
If the skin microbiome is unbalanced, it can lead to acne, psoriasis, eczema, sensitivity,...
Here is a summary of the different types of cosmetic products that can be linked to the microbiome:
EQUIBIOME™ is extracted from the roots of the Great burdock, traditionally used in chinese medicine to treat skin disorders.
Bacteria live in communities, and produce extracellular substances to hold communities together, forming a biofilm.
Some bacterial biofilms have been associated with atopic dermatitis, especially Staphylococcus aureus and Propionibacterium acnes ones. 
Equibiome™ doesn’t negatively affect microbial growth, but prevents S. aureus biofilm formation, thus restoring a good skin barrier function.
Equibiome™ also acts as a peacekeeper by managing the inflammatory processes of sensitive skin, producing less defenses against microorganisms and restoring a dynamic equilibrium between skin and microbes.
The skin is significantly moisturized (+56% vs placebo after 21 days), and less sensitive ( -60% skin redness apparition & -20% burning/stinging sensations vs placebo at D14).
EMOGREEN™ L19 is a non-polar and natural oil, with a fresh gliding sensation and a soft finish. The perfect alternative to silicone oils.
Our recent tests showed that EMOGREEN™ L19 contributes to a microbial growth on the skin, especially the germs involved in the hydrolipidic film production, thus helping the skin to restore its natural protective layer.
Results on very dry skin:
EMOGREEN™ L19 also allows to decrease the minimum quantity of preservatives needed to reach preservation criteria A (according to European Pharmacopoeia): less preservative in your formula = less preservatives on the skin!

FLUIDIPURE™ 8G is a combination of sugars and an AMINOVECTOR™ of glycine, a prominent amino acid in the NMF, in the collagen and known to prevent bacterial growth.
FLUIDIPURE™ 8G helps restoring a healthy skin environment by:
Dandruff and unpleasant odors are reduced, so are scalp rednesses, greasiness and itchiness.
FLUIDIPURE™ 8G also reduces the concentration of preservatives needed in the formulas, thus making formulations milder.
