KératinocytesLes kératinocytes sont des cellules constituant 90 % de la couche superficielle de la peau (épiderme) et des phanères (ongles, cheveux, poils, plumes, écailles). Ils synthétisent la kératine (kératinisation), une protéine fibreuse et insoluble dans l'eau, qui assure à la peau sa propriété d'imperméabilité et de protection extérieure.
L'épiderme est divisé en 4 couches basées sur la morphologie des kératinocytes (de l'intérieur vers l'extérieur) :
1. stratum germinativum (couche basale à la jonction avec le derme)
2. stratum spinosum
3. stratum granulosum
4. stratum lucidum
5. stratum corneum
Les kératinocytes passent progressivement de la couche basale vers les couches supérieures par différenciation cellulaire jusqu'au stratum corneum ou ils forment une couche de cellules mortes nommées squames, par apoptose. Cette couche constitue une barrière de protection et réduit la perte d'eau de l'organisme.
Les kératinocytes sont en perpétuel renouvellement. Ils mettent environ 1 mois pour aller de la couche basale au stratum corneum mais ce processus peut être accéléré en cas d'hyperprolifération de kératinocyte (psoriasis).

Tests de sécuritéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Vitamin C60 BioResearch Corporation has developed the world’s first cosmetic ingredient containing 2-aza-8- oxohypoxanthine (AOH), under the trade name Repista. This article describes the cellular activation effects of the AOH active ingredient on normal human epidermal keratinocytes. DNA microarray analysis using NHEKs suggested the AOH active ingredient promotes epidermal turnover, differentiation, and maturation, as well as the metabolism of old skin cells. In addition, all tests in the safety evaluation conducted on the AOH active ingredient were negative, indicating that it is a safe cosmetic ingredient. Note de contenu : - What is Repista ?

- ECOTOXICITY STUDIES : Growth inhibition study of bacillus ferment filtrate extract on freshwater algae (pseudokirchneriella subcapitata) – Ready biodegradability – Stability and future applicationsNote de contenu : The concepts in beauty are constantly changing, bringing novel innovations in the cosmetic industry. The industry is also adapting to eco-friendly ingredients and packaging technologies, biodegradable cosmetics, environmentally safe products, and innovations to preserve the skin microbiome. We have earlier reported the extracellular metabolite from the probiotic strain Bacillus coagulans MTCC 5856 to have antimicrobial and skin protection activities. We examined the skin and environmental safety aspects of the ingredient in the present study. The studies were conducted as per the Organization for Economic Co-operation and Development (OECD) guidelines. Mutagenicity potential was studied by the Ames test. Environmental safety was conducted to assess the effect of the ingredient on microalgae and other zooplankton. LactoSporin was found to be safe in the ecotoxicity studies at a concentration of 100 mg/ L. It was readily biodegradable and was nonmutagenic. These results suggest that LactoSporin is an eco-friendly cosmetic ingredient with antimicrobial and skin-protecting properties.

VectorisationIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : Organic silicon has been linked to positive effects on the skin rejuvenation, mainly by the oral route. Thus, the main objective of the present study was to assess whether monomethylsilanetriol (MMST, a source of organic silicon) can deliver silicon to the epidermis and dermis, when applied topically in a cream. Once the hypothesis was confirmed, the present study also evaluated whether the product was toxic to keratinocytes ; additionally, its possible antioxidant activity was assessed.
- Methods : The ex vivo skin permeation profile was determined using human skin in Franz-cells equipment; cytotoxicity was assessed using HaCaT keratinocytes. Antioxidant capacity was determined as scavenging activity, measured according to the 1,1-diphenyl-2-picrylhydrazil free radical method.
- Results : The permeation percentage was almost 60% of the applied MMST, with a large quantity of drug found in the viable epidermis and dermis. The cell viability assay showed no significant difference in the percentage of viable keratinocytes among the treated groups at the doses used. In terms of antioxidant activity, the IC50 value obtained was 2400 μg mL−1. Low antioxidant activity, negligible toxicity for keratinocytes and a significant percentage of permeation were observed.
- Conclusion : We provide evidence that MMST applied topically can deliver silicon to the skin in biorelevant levels for cosmetic purposes.Note de contenu : - MATERIALS AND METHODS : Si quantification - Ex vivo skin permeation - Cytotoxicity : cell viability assay - Antioxidant activity

Tests de sécuritéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : A 2-year sampling campaign was realized on French Mediterranean beach (Palavas-les-Flots Hérault) in order to measure the concentration of UV filters released from the sunscreen used by bathers. Multiple factors suspected of playing determining roles in the UV filter pattern in water were explored, such as the seasonal and daily time evolutions, or the vertical and horizontal distributions, and they were regarded through the UV filter characteristics.
- Methods : The beach was monitored during periods of high and low tourist attendance, typically before, during and after the summer peak. The beachgoers attendance was counted. Bathing water was sampled distinctly from the bulk column and from the top surface layer, testing different sampling tools. Sediments and mussels were also sampled and analysed as potential UV filter sinks. Three organic UV filters (octocrylene OCR, avobenzone BMDBM and octyl methoxycinnamate OMC) and one mineral (titanium dioxide TiO2) were studied here as representatives of the current cosmetic market.
- Results : Summer peak attendance on the beach was confirmed associated with peak levels of UV filter concentration in the bathing water, even more pronounced during a heat wave period. This relation was also observed at day scale with an afternoon peak, suggesting a rapid evolution of the UV filter pattern in water. Contrasted fates were measured between the four studied UV filters, that could be mainly explained by their respective characteristics, i.e. particulate or dissolved, hydrophilic or lipophilic, lifetime. Generally, this resulted in a concentration ranking TiO2 > OCR > OMC > BMDBM, ranging from 0.5 to 500 μg/L. The most lipophilic and recalcitrant OCR was found most vertically differentiated and over concentrated in the top surface layer of water. Finally, a large horizontal heterogeneity was also observed in the UV filter concentration pattern, raising the need for sample replicates that cover a significant area.
- Conclusion : This work fulfils some knowledge gaps on the issue of UV filter release in coastal environments, not only by providing original field data and methodological recommendations but also importantly in the comparison made of organic and mineral UV filters, which are often considered separately and rarely evaluated at the same time.Note de contenu : - MATERIALS AND METHODS : Study site: Palavas-les-Flots Beach - Sampling methods - Geographical recordings - Water analysis - Polypropylene sorbent sheet analysis - Sediment analysis - Mussel analysis
