Claim substantiation and human testing for cosmetics always remain between science & marketing. Marketers feel more and more comfortable with scientific proofs and vice versa. We will meet both those who are present at Cosmetic360 Paris [booth H29] and SFI2C conference in Marrakech, to pursue our collaborative work of testing intermediation. In this newsletter, we will tell you about the assessment of the cutaneous microbiote and the complexion radiance evaluation on human. We will also provide news of our partners in instrumentation and testing laboratories.

We will have a focus of the last news of our partners :
CERCO, COSDERMA, COSMEPAR GROUP, DERMSCAN GROUP, EOTECH, EUROFINS, IEC, INNOFAITH, LIPOTYPE, MAVIG, OXIPROTEOMICS, QACS LAB, SPINCONTROL,
100 trillion bacterial cells (microorganisms, bacteria, viruses, fungi, yeasts) are living in our bodies. Everybody wants to know more about the impact of the cosmetics use on the skin bacteria.
The microflora is usually subdivided in 2 groups:
The balance of the cutaneous microflora (500 bacteria species) is dependent of the conditions of its ecosystem: temperature, pH, UV, lipids, proteins, etc. It is mainly influenced by the genetic, the life style and the diet. Each person has their own skin flora composition, distributed from the epidermis until the dermis, which is lifelong qualitatively stable, like a personal microbial footprint. This microflora is fundamental for the skin homeostasis and participates to the immune and barrier functions. The cosmetics offer for 2 main benefits: the probiotic-like effect and the anti-microbial effect.
What methods exist today to evaluate the cutaneous microbiota?
The important intra-individual diversity of the cutaneous flora is also associated with a high level of inter-individual variability. Thus, the protocols will compare the skin swabbing of the treated zone and of the non-treated or placebo zone, before and after treatment.
Two main diagnosis opportunities:
The microbiota will play a key role in the cosmetics of tomorrow. We move towards personalized and preventive cosmetics. Claim substantiation will evolve with the regulation and the products development.
