Spectroscopie RamanIndex. décimale : 668.5 Parfums et cosmétiques Résumé : In the field of corneobiology, the skin barrier has been pointed out to play a crucial role in skin homeostasis. In the treatment of dry skin, it is important to repair and augment the skin barrier in order to achieve positive and long-lasting results. To adequately describe the hydration state of the human skin, a number of complementary measuring techniques are often employed. Therefore, besides the classic methods of corneometry and the determination of the transepidermal water loss, we tested our moisturising active Hydro-Gain and the two industry standards, glycerol and hyaluronic acid, in a PCR-array and in a study using confocal Raman spectroscopy. In the comparison to glycerol and hyaluronic acid, Hydro-Gain gave the best results regarding skin moisturisation and we also found evidence that Hydro-Gain stimulates strengthening of the skin barrier.

NickelLe nickel est un élément chimique, de symbole Ni et de numéro atomique 28.
Le nickel est un métal blanc argenté qui possède un éclat poli. Il fait partie du groupe du fer. C'est un métal ductile (malléable). On le trouve sous forme combinée au soufre dans la millérite, à l'arsenic dans la nickéline.
Grâce à sa résistance à l'oxydation et à la corrosion, il est utilisé dans les pièces de monnaie, pour le plaquage du fer, du cuivre, du laiton, dans certaines combinaisons chimiques et dans certains alliages. Il est ferromagnétique, et est fréquemment accompagné de cobalt. Il est particulièrement apprécié pour les alliages qu'il forme.

Protection cutanéeIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : Barrier creams (BCs) are marketed as locally applied medical devices or cosmetic products to protect the skin from exposure to chemicals and irritants. Generally, the mechanism of action of such products is mainly due to the formation of a superficial thin film between the skin and the irritant or sensitizer, thus reducing or totally blocking the cutaneous penetration of such agents. Specifically, studies focusing on the effectiveness of commercial protective creams to prevent nickel cutaneous penetration are extremely scarce. The aim of the current work, therefore, is to evaluate the protective role of a commercially available barrier cream for nickel and compare the results with a simple moisturizing, following exposure to Ni powder.
- Methods : Marketed BCs were evaluated and tested. Human skin absorption of Ni was studied in vitro using static Franz diffusion cells.
- Results : Our results demonstrate that the application of both formulations caused a reduction of Ni inside the skin (8.00 ± 3.35 μg cm−2 for the barrier cream and 22.6 ± 12.6 μg cm−2 for the general moisturizing product), with the specialized barrier cream being statistically (p = 0.015) more efficient on forming a protective barrier, thus evidencing the importance of some ingredients in such formulations on the nickel dermal accumulation.
- Conclusions : The composition of the formulations based on film-forming or chelating agents may play an imperative role in reducing the cutaneous penetration of Ni.Note de contenu : - MATERIALS AND METHODS : Materials - Formulation - Preparation of nickel powder in synthetic sweat solution - Skin samples preparation - Skin digestion after the experiment - Analytical measurements - Statistical analysis

ProbiotiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Modern cosmetics is demanding of ingredients able to positively interact with skin ecosystem in which billions of microorganisms live and where the equilibrium of protective and pathogens should be maintained. The beauty industry is moving forward to find the way to incorporate in cosmetics recipes probiotics, prebiotics or probiotic derived ingredients, well known in food supplement market.
The present paper aims at demonstrating the efficacy of a specific probiotic-derived ingredient able to strengthen skin barrier and its natural defenses promoting skin ecosystem well-being by preventing pathogens colonization.Note de contenu : - Methodology

Produits hydratantsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : The moisturizing performance of Gmoist® Sea-Gel was evaluated based-upon 14 healthy volunteers. It was found that skin moisture content markedly increased and TEWL effectively decreased after Gmoist® Sea-Gel applied for 7d. Then using real-time fluorescence quantitative PCR technology, HaCaT cells were cultured with Gmoist® Sea-Gel to study six genes ex¬pression level related to skin hydration and barrier function. Results showed Gmoist® Sea-Gel significantly promoted the INV, TG-1, FLG and CASP-14 mRNA's expression after 24 hour's treatment. Gmoist® Sea-Gel can upregulate cornified cell envelope related genes expression, promote the degradation of filaggrin into natural moisturizing factors to strengthen skin hydration and barrier function.

Tailles des cellulesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : The purpose of this pilot in vivo study was to investigate corneocyte size and transepidermal water loss (TEWL) in facial cheek and volar forearm skin as a function of consecutive tape stripping. Changes in corneocyte size and transepidermal water loss (TEWL) were measured as a function of stratum corneum (SC) depth at both anatomical sites. To our knowledge, this is the first published quantitative comparison based on these parameters. This work complements our previously published studies on face skin barrier recovery at 24 h and 4 weeks post-tape stripping [Gorcea et al., Skin Res. Technol., 19, 2013, e375-e382 ; Gorcea et al., Int. J. Cosmet. Sci. 35, 2013, 250].
- Methods : Transepidermal water loss in vivo measurements of forearm and facial skin sites were taken before tape stripping commenced (baseline) and after each tape was collected. Optical microscopy and image analysis techniques were employed to characterize corneocyte size as a function of skin depth (tape strip number) for both anatomical sites.
- Results : Transepidermal water loss increased significantly from baseline with sequential tape stripping at both anatomical skin sites. Volar forearm skin required approximately three times as many tapes to 'damage' the SC barrier (arbitrarily defined as twice baseline TEWL) compared to facial cheek skin demonstrating significant differences in barrier properties between cheeks and forearms (P < 0.05). Corneocyte size decreased significantly with depth for both sites (P < 0.001). Corneocytes from face skin were significantly smaller than corneocytes from volar forearm skin.
- Conclusion : Statistically significant differences between facial and body skin stratum corneum cell morphology and transepidermal water loss were demonstrated and quantitatively measured as a function of tape stripping.Note de contenu : - METHODS : Volunteer recruitment - Tape stripping - Transepidermal water loss - Corneocyte surface area- Statistical analysis
