Vieillissement cutanéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Le vieillissement cutané est un phénomène multifactoriel entraînant de nombreux changements fonctionnels et esthétiques. Les travaux récents en biologie cutanée ont permis d'accroître la connaissance sur le processus de vieillissement, ainsi que sur les mécanismes et la contribution des UV dans le photovieillissement. Ces connaissances ont conduit au développement de nombreuses stratégies de traitement visant à prévenir le photovieillissement, voire à relancer certaines activités biologiques. Cet article présente l'impact de la lumière solaire sur la peau, puis les signes cliniques et les mécanismes du photovieillissement, et enfin une revue des principaux moyens mis en oeuvre dans sa prévention et son traitement.

Nanoparticles have shown a positive development due to its own various properties, functionalities and its applications in Cosmetics. One example where consumer expectations grow and the demand increases are UV protectors or sun creams. It was concluded that nanoparticles can be used in cosmetics like sunscreen to increase UV protection and prevent bacteria growth simultaneously. The available products are characterized by advantages and disadvantages of the various UV protection factors, and so far, no single material combines all desired properties. Nanotechnology shows an advantage character as it can be used to change the properties of the finely produced nanoparticles and influences products from various sectors as well as industries for a wide variety of applications, UV protection being amongst them.

Tests d'efficacitéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : As a result of their complex aetiology and periodicity, dark circles are difficult to characterize and measure, with current assessment techniques relying on specialist equipment, image analysis or proprietary grading scales. There is therefore a need to develop and validate a photonumeric scale for assessing infraorbital dark circles, which can provide an objective and consumer relevant tool for evaluating this condition and the efficacy of treatment products and procedures.
- Methods : A panel of expert clinical evaluators reviewed approximately three thousand facial photographs collected over a 5-year period and selected images representing a dynamic range of dark circles. A 10-point photonumeric scale was created, with corresponding descriptors and images for each grade of the scale. To rigorously validate the scale, linearity, sensitivity and precision were assessed by colorimetry and in-clinic evaluation. Reproducibility was assessed photographically with both experienced and inexperienced clinical evaluators, whereas intragrader repeatability was assessed live in-clinic. The scale was then employed in a split-face randomized clinical trial on 58 subjects to evaluate the efficacy of a cosmetic treatment product over 8 weeks.
- Results : Colour analysis of the images showed the scale was linear, with statistically significant correlations observed when colour data (CIElab; Individual Typology Angle) were plotted against the corresponding grades (r > 0.9, P < 0.001). Colour difference (Delta E) was calculated between the infraorbital zone and the surrounding skin, and when data were plotted against the grades, a statistically significant correlation was observed (r = 0.99, P < 0.01). The magnitude of the Delta E suggested that changes in grade are visibly perceptible to the human eye, and therefore, the scale is sensitive and clinically relevant. Intergrader reproducibility showed strong correlation (0.96) and >90% agreement between experienced evaluators, whereas intragrader repeatability assessment showed >90% perfect agreement between grades. Use of this scale in a clinical trial demonstrated the efficacy of a cosmetic product, with a mean statistically significant (P < 0.001) decrease in grade of 0.74 compared to baseline, and 0.59 versus the untreated control, after 8 weeks of treatment.
- Conclusion : Our photonumeric scale for infraorbital dark circles is sensitive and robust and provides an objective and easy-to-use tool to evaluate dark circles and their treatment.Note de contenu : - MATERIALS AND METHODS : Creation of a photonumeric scale for infraorbital dark circles - Validation of the photonumeric scale - Clinical trial to evaluate the efficacy of a cosmetic treatment product

Produits antisolairesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : In 2017, Cosmetics Europe performed a double‐blinded ring test of 24 emulsion‐type sunscreen products, across 3 in vivo test laboratories and 3 in vitro test laboratories, using a new candidate in vitro SPF test method. Based on the results of this work, an article was published showing how data derived from a new lead candidate method conform to new International Standards (ISO) acceptance criteria for alternative SPF test methods (Any alternative method should consider the matrix effect and if required, specify the matrix applicability of the method; Criterion 1a: Systematic differences between methods should be negligible: 95% of all individual results of an alternative method are within the range of ±2× reproducibility standard deviation of the in vivo method, that is overall bias must be below 0.5× reproducibility standard deviation of the in vivo method; Criterion 1b: Measurement uncertainty of an alternative method should be below the measurement uncertainty of the in vivo method. Candidate method predicted values must fall within the full ‘funnel’ (SPF 6‐50+) limits proposed by Cosmetics Europe (derived from the same minimum test design, that is using the ISO24444 Method to measure at least 24 products across at least 3 laboratories using at least 5 test subjects/laboratory, in a blinded fashion).). Of the 24 sunscreen products tested, the majority of emulsions were of the oil‐in‐water (O/W) type, whereas only one was water‐in‐oil (W/O) and there were no products with a mineral‐only sun filter system. In order to confirm the scope of this method, therefore, a new study was conducted that included 73 W/O (12 mineral + organic, 44 mineral only and 17 organic only) and 3 O/W mineral‐only, emulsion‐type sunscreen products (a total of 76 new sunscreen products). When combined with the previous 24 products (tested in 3 different laboratories), this yielded a new data set comprising a total of 100 emulsion‐type sunscreen products, with SPF values ranging from 6 to 50+ (with a total of 148 data points). These products were tested using the double‐plate in vitro SPF test method and compared with the ISO TC217/WG7 acceptance criteria for alternative SPF test methods. Over 95% of paired in vitro: in vivo SPF values lay within the upper and lower limits of the ISO acceptance criteria funnel, with no bias. This new in vitro SPF test method, therefore, meets the minimum requirements for an alternative SPF test method to ISO24444:2010, for emulsion‐type sunscreen products (which make up the majority of marketed sunscreen products).

Procédés de fabricationIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Process validation for cosmetic products is a requirement under GMP so that manufacturers can prove control of critical aspects of their operations. Cosmetic formulators always need to work closely with process and manufacturing engineers during the formulation development and scale-up stages in order to be able to put in place suitable and realistic methods for manufacturing cosmetic products. Formulating a product at lab scale so that it can be produced on a large scale is a complex process. Most issues that come to light during the scale-up process are usually due to inaccuracies found in the processing method, therefore it is important that the processing method put in place to manufacture a product produces consistent results so that the product retains its quality during its lifespan.
