The evaluation of the effect of dermocosmetics or active products on the skin microbiota is evolving into more and more complex models. And yet, these never reach the sophistication of the ecosystem of the bacterial biofilm of the skin. In addition, it is now known that the skin microbiome is subject to intra-individual variations depending on the body areas and inter-individual according to genetic, intrinsic, and environmental factors.
A complex ecosystem deeply linked to the skin homeostasis
Healthy skin promotes a skilled balance of the different bacteria present and vice-versa, skin homeostasis involves a diverse and highly controlled microbiome. Sometimes the simple decrease of one species can benefit others, which then become potentially pathogenic. 2D or 3D models including the inoculation of one or more microorganisms, living, or inactivated, allow to progress on specific problems, such as those associated with dysbiosis such as acne, atopic dermatitis, psoriasis, or scalp disorders…
These approaches, which can sometimes be considered “reductionist” as the bacterial ecosystem of the skin is complex, remain unavoidable and contribute to the advancement of knowledge in the fields of skin biology and microbiology. The intra and inter variability in skin microbiota characteristics is large and it is difficult to sy how a good microbiota should be. The diversity of microbiota species (number and diversity) that is influenced by urban way of life and excessive hygiene, plays a major role in the healthy skin conditions.
Microorganisms and hosts skin cells are in a continuous relationship to insure a healthy skin balance. Various scientific research demonstrate that the biofilm of the skin, constitutes by microorganisms and host cells, maintains skin immunity and supports the good skin barrier (i.e. Atopic Dermatitis)
Cosmetics should preserve this bacterial balance of the skin as varied as it may be and allow fragile and injured skin to regain a natural biofilm.
Since the discovery of the intestinal microbiota, the question of the skin microbiota (micro-organisms, bacteria, viruses, fungi, yeasts), is under every lip. 100 trillion of bacteria are living in our bodies and everybody wants to know more about the impact of the cosmetics use on the skin bacteria ecosystem and how these phenomena can be measured?
- the transient flora, saprophytic and pathogens microorganisms with Staphylococcus, aureus, Escherichia coli, Pseudomonas aeruginosa and Bacillus species…
