The skin microbiota is a collection of bacteria, fungi, viruses and microscopic animals that we collected during our lifetime. These microorganisms have become an essential part of the epidermis.1
They protect us against pathogenic invasions. Just like the human society, the microbiota is meticulously organised. Although most aspects of this ingenious microbial organisation remain hidden to us through a veil of mystery, one aspect is partially revealed: the members of the skin microbiota need food to survive and to thrive. Microorganisms are endlessly resourceful because they possess 15 million genes.2 However, they are powerless without the appropriate food supply. No food means no gene expression.
With DNA sequencing the disturbance of preservatives and mild natural surfactants on the skin microbial community has been clearly mapped. The supporting effect of a specific molecular weight Inulin on the ingenious microbial food supply has been revealed in vivo. Through this mechanism Inulin is a necessary asset for the skin and the skin microbiota to perform all their essential tasks. Inulin is an essential skin care ingredient to keep the skin healthy.
One of the major functions of the skin; protecting the body against the environment, is performed thanks to the symbiosis between the human skin cells and the microbial layer.3, 4 The human skin is contributing to this symbiosis by delivering food to the skin microbiota. The major foods delivered by the skin to the skin microbiota are:
