MélasmaLe mélasma (également dénommé chloasme ou chloasma) est une affection bénigne de la peau se présentant sous la forme de taches hyperpigmentées apparaissant sur les zones exposées au soleil, surtout au niveau du visage, du décolleté et du cou.
Le mélasma atteint principalement les femmes, le plus souvent lors de la grossesse, donnant ce que l'on appelle communément le masque de grossesse, mais il peut apparaître en dehors de celle-ci.
Les causes et les facteurs favorisants du mélasma sont essentiellement des facteurs de prédisposition génétique, l’exposition au soleil et aux œstrogènes (lors de la grossesse ou au cours d'une contraception).

In this study, we assess the protective effect of a sunscreen (TDF® Blu Voile Sunscreen) in protecting the skin against the harmful effects of blue light irradiation in vivo and through the in situ quantitative and qualitative evaluation of protein carbonylation in human skin explants.
- Methodology : The protective effect of the test product against blue light was first evaluated ex vivo on human skin explants. The treated and non-treated explants were exposed to 14 J/cm2 of blue light 460 nm following which the protein carbonylation was evaluated by in situ epifluorescence imaging and separation by high-resolution gel electrophoresis. To determine whether the test product could also protect against the immediate and persistent pigmenting effect of blue light, two randomized in vivo studies were conducted, which included respectively 17 subjects with a skin phototype of IV and V (Fitzpatrick classification) and 22 subjects with a skin phototype of IV, V, and VI (Fitzpatrick classification). The duration of the study for each subject was 2 days (D1 and D2) for immediate observations and 5 days (D1–D5) for persistent observations. Specific zones on the subjects' back were either left non-treated or treated with the test product and were then exposed to a unique dose of blue light 415 nm. The onset of pigmentation between the treated and exposed zones was then assessed relative to the non-exposed treated zone through colorimetric measurements of the Individual Typology Angle (ITAo).
- Results : Human skin explants treated with test product showed significantly lower levels of accumulated carbonylated proteins, with a protection of 82%, following exposure to blue light 460 nm. Findings of the in vivo studies also indicated that the test product presented significantly better protective efficacy against immediate and persistent pigmentation induced by blue light 415 nm.
- Conclusion : Hence, it can be concluded that the test product can protect against the oxidative stress as well as the immediate and persistent pigmentation induced by blue light.Note de contenu : - MATERIALS AND METHODS : Test compounds - Blue lights doses - Ex vivo protein carbonylation study - Human skin explants preparation - In situ visualization and semi-quantification of carbonylated proteins - Extraction and absolute quantification of carbonylated proteins - Statistical analysis - In vivo clinical study with volunteers - Evaluation against the immediate pigmenting effect of blue light - Evaluation against the persistent pigmenting effect of blue light - Colorimetric measurement - Statistical analysis

Spectroscopie de résonance paramagnétique électroniqueIndex. décimale : 668.5 Parfums et cosmétiques Résumé : A scale of skin treatments is analysed, which bases on the detection of UV-generated free radicals in pig skin. Physiological and anatomical similarities between man and pig made this animal a good model for man in many research areas. The determination of the Radical Status (free radical response) offers the possibility to see in an early stage the effect of exterior and interior influences. The detection of the skin’s response after a normalized radical generation by defined UV dose combined with the application of external and internal influences enables a comprehensive and easy classification of skin products and therapies. The effect of substances, especially, applied topically on the skin, like it is usual in cosmetics and pharmacy, can be classified. The relevance of the RSF method is demonstrated with the application of numerous different treatments on the skin.

Langues : Anglais (eng) Catégories : Produits antisolaires Tags : 'UVA INDEX' protection' 'Méthode de test In-vitro' 'Protection solaire' Reproductibilité Index. décimale : 668.5 Parfums et cosmétiques Résumé : Due to overexposure to UVA and not only to UVB light significant alterations in damage to human skin were observed. Accordingly, the protection against UVA is a major additional requirement for sunscreens beside the effective prevention of sunburn. Despite the intensive debate on the appropriate measurement and labeling, up to now, no proposal was officially accepted in Europe and US. The recently published determination of the in-vitro PPD protection factor [1] was discerned as a candidate for future, harmonized UVA protection measurement? The method combines the merits of in-vitro as well as of in-vivo determinations. The aim of the present study was to investigate the inter-institutional reproducibility of the new UVA parameter and to determine how to express the UVA protection. Concerning the latter aspect, particular emphasize should be given to the importance of the SPF by describing the UVA protection in relation to the UVB protection efficacy. Seven laboratories participated in the Round Robin study and five marketed sunscreen formulations were tested. The sunscreens were selected to represent the major types of sun protection products. The application amount was fixed at 0.75mg/cm2 for all samples and for all institutes after ensuring in a pretest that the absorbance does not exceed the value of 2.0, because otherwise saturation phenomena could occur. Regarding the calculation of the in-vitro PPD protection factors, a high reproducibility was found. The average standard deviation for all five products was less than 15%. The good correlation between in-vitro and in-vivo PPD factors confirms the relevance of this methods. The UVA INDEX was defined as the relation between the in-vitro PPD factor and the labeled in-vivo SPF. Based on the simple transmission measurement and a calculation that takes into account the in-vivo effectiveness as references, it provides a rapid and valid procedure to evaluate and to differentiate the UVA protection of sunscreens. According to these findings, the UVA INDEX is seen as a potential candidate for UVA determinations. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=10639

Soins de beautéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Over the past decade the beauty industry has been transformed by an increasing global demand for cleaner, safer and more sustainable beauty products. As a result, we have seen the evolution of the clean beauty trend. There is no singular definition for clean beauty, as it means different things to different people-consumer to consumer, brand to brand. Clean beauty embraces both natural and synthetic ingredients, focusing on safety over source. It is important to remember that not all 'natural' ingredients are safe - we would not use poison ivy or lead in a skin care product, and that not all synthetic ingredients are unsafe. 'Clean' should not be confused with 'natural' as a brand can be considered 'clean' without being 'natural'. Note de contenu : - Clean sunscreens

L’utilisation accrue des particules de TiO2 l’échelle du nanométre a engendré des questions sur tous les produits contenant des matériaux nano-échelle. Cette étude examine les effets de l’utilisation de particule de TiO2 a l’échelle du nanomètre sur l’atténuation des rayons UV dans les formulations de crème solaire simple et complexe. Nous avons étudié l’atténuation de la luminosité ultraviolet (UV), la stabilité du produit et les effets sur la fonction barrière de la peau, avec les particules de TiO2 nano-échelle et micro-échelle. Les résultats indiquent que les particules a l’échelle du nanométre, enduits et non-aggloméré, fournissent une excellente atténuation UV, sans diminuer la fonction barrière de la peau. Ceci suggére que les particules de TiO2 a l’échelle du nanométre ont une meilleure efficacité, sans poser des inquiétudes en ce qui concerne leur securité.
