These properties are discussed in this short review, in particular, the physical and chemical barrier characteristics of the stratum corneum, which we now know are only possible due to the presence of water at precise and carefully controlled levels and locations. The review discusses the pivotal role water plays in both stratum corneum mechanics/integrity and stratum corneum regulation/maturation and reinforces the critical role played by cosmetic products, which "moisturize" and augment statum corneum barrier function.

Simulation, Méthode deIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Contrary to the skin biological end points used for determination of the sun protection factor and UVA protection factor, generation of excess free radicals in skin mainly reactive oxygen species is potentially the source of much skin damage and soo represents a more general biophysical answer to the effects of sun exposure of different wavelengths. By applying electron spin resonance spectroscopy to human skin biopsies, we determined in previous work a free radical action spectrum covering the ultraviolet and visible light range. Convolution of the action spectrum with sunlight spectral irradiance (280nm-700nm) showed the importance of visible light in free radical generation. This unexpected finding led us to perform further investigations. Firstly, an existing sun simulator was modified so that its outputtruly mimics the sun's full spectrum, including visible light. Human skin biopsies were irradiated either by this device or a conventional UV source, confirming our previous calculations : half of the free radicals are generated in the 400-700nm visible wavelength range.
Secondly, the visible spectrum of the modified sun simulator was divided into narrow-band lights using different pairs of short and long pass-filters. Human skin biopsies impregnated with specific spin traps were exposed to the different narrow-band lights in order to identify different types of free radicals. Generation of dangerous radical species like O2, OH and CH-R was observed in different parts of the visible range, confirming the relevance of the free racial action spectrum and its ability to predict skin protection.Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=3807

The cornified envelope is the final skin barrier which protects against external aggressions such as UV light and reduces water loss. Skin aging is associated with decreased functionality of this barrier and reduced epidermal differentiation. We present a new bioactive complex for the stimulation of protein synthesis associated with cornified envelope and markers of epidermal differentiation. Composed of a hydrolyzed oat protein extract and particularly the synthesis of proteins such as filaggrin, late envelope protein and small proline-rich proteins, all markers of epidermal differentiation, in a reconstitued human skin model as measured by DNA array chip analysis, reverse transcription-polymerase chain reaction and immunohistochemistry. When a cream containing 3% of this bioactive complex was applied to the skin of 25 human volunteers, an increase in skin hydration of more than 60% after 14 days of application and a reduction of wrinkles and roughness by more than 50% in 4 weeks were observed compared with a placebo cream. In conclusion, the bioactive complex stimulated synthesis of proteins which are important for epidermal differentiation and skin barrier function and was helpful infighting skin aging.
