[article]  inSOFW JOURNAL > Vol. 145, N° 12 (12/2019) . - p. 24-26 Titre : Breaking new ground in the exploration on skin microbiome Type de document : texte imprimé Auteurs : Catherine Zanchetta, Auteur ; Mathias Fleury, Auteur ; Denis Whaler, Auteur ; Mélanie Pélican, Auteur Année de publication : 2020 Article en page(s) : p. 24-26 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Biomolécules actives Dermo-cosmétologie Microbiome cutané Peau -- Soins et hygiène Produits hydratants Index. décimale : 668.5 Parfums et cosmétiques Résumé : Yogurtene® Balance is a mix of spray dried yogurt and inulin, a vegetable fructose polysaccharide derived from chicory which has been widely used for its gut microbiome health benefits, due to its prebiotic activity. Thanks to this unique composition, Yogurtene® Balance is able to protect and rebalance the skin microflora towards one of a typically younger skin, while significantly improving skin hydration. The active, rich in yogurt constituents and prebiotics supporting the skin friendly bacteria, was deeply studied by Givaudan Active Beauty researchers. Its performance was clinically proven in a rinse-off application (bar soap), demonstrating the impact of Yogurtene® Balance on skin microbiota composition. i-MAPS, the first instant microbiome analysis and profiling system, is a scientific breakthrough combining microbiome research and new technology that opens the door for customers to explore the personalisation of beauty products involving the skin microbiome. Using bioinformatics, i-MAPS uses a combination of different techniques in a specific sequence to create individual profiles by mapping the skin microbiome in approximately seven hours compared to seven days for a standard analysis. Every profile provides exclusive information about the bacteria present on the microbiome and correlates it to a skin type such as oily, sensitive, or prematurely ageing.

Evaluation of the hydrating benefits of a cationic hyaluronic acid : From biological evaluation to consumer home use trial / Justine Blanc Catala in INTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Vol. 46, N° 5 (10/2024)  

[article]  inINTERNATIONAL JOURNAL OF COSMETIC SCIENCE > Vol. 46, N° 5 (10/2024) . - p. 795-805 Titre : Evaluation of the hydrating benefits of a cationic hyaluronic acid : From biological evaluation to consumer home use trial Type de document : texte imprimé Auteurs : Justine Blanc Catala, Auteur ; Catherine Zanchetta, Auteur ; Candice François, Auteur ; Emilie Chapuis, Auteur ; Nathalie Joset, Auteur ; Marie Meunier, Auteur ; Florian Loeser, Auteur ; Shan Godbille, Auteur ; Amandine Scandolera, Auteur ; Romain Reynaud, Auteur ; Fabrice Lefevre, Auteur Année de publication : 2024 Article en page(s) : p. 795-805 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Analyse sensorielle Consommateurs -- Préférences Cosmétiques Dermo-cosmétologie Evaluation Hyaluronique, acide L'acide hyaluronique est un type de polysaccharide (plus précisément une glycosaminoglycane) non fixé à une protéine centrale et largement réparti parmi les tissus conjonctifs, épithéliaux et nerveux animaux. Il se trouve notamment dans l'humeur vitrée et le liquide synovial. Il est l'un des principaux composants de la matrice extracellulaire ainsi que de certaines mucoprotéines lorsqu'il est associé à une fraction protéique. Depuis les années 1990, il est très utilisé dans divers dispositifs médicaux, médicamenteux et cosmétiques (présenté dans ce dernier cas comme "antistatique, humectant, hydratant, conditionneur cutané, anti-âge, etc."), bénéficiant d'un effet de mode grandement soutenu par une large publicité commerciale. Contribuant de façon significative à la prolifération et à la migration des cellules, l'acide hyaluronique est aussi impliqué dans la progression de certains cancers. (Wikipedia) Justification de l'allégation Peau -- Soins et hygiène Produits hydratants Statistique Index. décimale : 668.5 Parfums et cosmétiques Résumé : Active ingredients are often assessed based on physiological measurements, but innovative technologies to measure skin sensations can provide a holistic volunteer assessment of the use of an ingredient. In this paper, the hydrating benefits of a cationic hyaluronic acid (HA) were evaluated alongside clinical biometrics and innovative cognitive measurements to determine how biological benefits correlated with volunteers' feelings and perceptions of hydration. The results demonstrated that cationic HA provides hydrating benefits at the clinical level due to its film-forming properties. Through the use of innovative behavioural measurement tools, we were able to show that these outcomes are perceived by naïve consumers in real-life conditions. In addition, the benefits of cationic HA reported by users were in accordance with the mental representation they had related to the use of HA, thus the product achieved complete sensorial embodiment. We can conclude that the combination of clinical evaluations and home use trials consolidates product assessment when seeking to measure consumer satisfaction with proven biological benefits.
