Visage -- Soins et hygièneIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Background : Facial skin is a particularly complex environment made of different skin types such as sebaceous (forehead) and dry (cheeks). The skin microbiota composition on different facial sites has not yet been addressed.
- Methods : We conducted a 4-week-long, single-centre, randomized and placebo-controlled clinical study involving 23 Caucasian females. We assessed both bacterial composition on five different facial areas and the microbiome modulatory effects resulting from the topical application of a plant extract (Epilobium fleischeri). Skin microbiome samples were collected before and after 4 weeks of product application. Microbiota profiling was performed via 16S rRNA gene sequencing, and relative abundance data were used to calculate differentials via a multinomial regression model.
- Results : Via ‘reference frames’, we observed shifts in microbial composition after 4 weeks of twice-daily product application and identify certain microbiota species, which were positively associated with the application of the product containing the Epilobium fleischeri extract. Staphylococcus hominis, Staphylococcus epidermidis, and Micrococcus yunnanensis appeared to be significantly enriched in the final microbiota composition of the active treatment group.
- Conclusion : Facial skin was found to be colonized by an heterogenous microbiota, and the Epilobium fleischeri extract had a modulatory effect on commensal bacteria on the different facial sites.Note de contenu : - INTRODUCTION : Objectives

shampooingsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : The human scalp is characterized by a moderately diverse microbial community, comprising prokaryotic (bacteria) and eukaryotic (fungi) members. Although the details are far from being fully understood, the human scalp microbiota is implicated in several scalp disorders, in particular dandruff formation. Hence, the protection of an intact and diverse scalp microbiota can be regarded as a quality criterion for hair and scalp care formulations. In this study, we investigated the influence of two commercially available, non-antimicrobial shampoo formulations on the structure of the scalp microbiota.
- Methods : Scalp microbiota samples, obtained by swab sampling from two cohorts of probands (n = 25, each), were analysed before and after daily use of two different shampoo formulations for 2 weeks, respectively. A polyphasic approach was used, comprising quantitative cultivation of bacteria and fungi on selective media as well as sequencing of PCR-amplified 16S rRNA and 18S rRNA genes, respectively.
- Results : All analyses revealed a microbiota composition typical for the human scalp. While in particular fungal germ numbers increased significantly during the treatments, overall bacterial and fungal community composition was not affected, based on alpha- and beta-diversity measures. However, we observed an increase in structural bacterial diversity with the age of the probands.
- Conclusions : Over an application period of 2 weeks, the investigated shampoo induced quantitative but no qualitative changes in the scalp microbial community structure of the investigated probands, suggesting no adverse but rather preserving or even stimulating effects of the underlying formulations on the scalp microbiota. Further investigation will have to clarify if this is also true for longer application periods and if the formulations might affect community functionality, for example microbial gene expression, rather than community composition.Note de contenu : - MATERIALS AND METHODS : Application study and scalp sampling - Microbiological cell counts - DNA extraction for molecular analyses - Library preparation and sequencing - Bioinformatical and statistical analyses

Peau -- Soins et hygièneIndex. décimale : 668.5 Parfums et cosmétiques Résumé : With age, the skin microbiome changes and evolves from producing a postbiotic of youth markers (Youth Biome Markers, YBMs) to secreting a postbiotic of ageing markers (Senile Biome Markers, SBMs). These SBMs are activated by Quorum Sensing, a microbial communication system which allows them to coordinate their behaviour, turning them more virulent and producing degradative enzymes. These enzymes are harmful for the skin and lead to the appearance of signs of ageing: inflammation, redness, pores, loss of firmness and appearance of wrinkles.
The active Quora Noniâ„¢ biomics, obtained from Morinda citrifolia (noni) stem cells, inhibits the Quorum Sensing. By doing so, it rejuvenates the skin microbiota, reducing the SBMs and therefore, the wrinkles. At the same time, it increases the skin firmness and improves the imperfections (redness and pores) on mature skin profiles.Note de contenu : - INTRODUCTION : Hallmarks of ageing and the role of skin microbiota - Does the skin microbiota also age? - Quorum sensing, SBMs and skin ageing

Tests cutanésIndex. décimale : 668.5 Parfums et cosmétiques Résumé : With concerns about the environment and limited natural resources continuing to grow, particularly among the younger generations, beauty biotechnology is likely to gain in importance over the coming years. DSM has therefore launched a new cosmetic grade of 1,3-propanediol in partnership with the biochemistry company Metex Nøøvista. The product has a fully sustainable production process, and its much indemand skin microbiome friendliness and multifunctional properties have been demonstrated in the studies described in this article. Because it helps to reduce the complexity of cosmetics formulations, this PDO offers manufacturers a way to meet growing consumer demand for sustainable but high-performance personal care products that are also seen as a clean option.
