Vieillissement cutanéIndex. décimale : 668.5 Parfums et cosmétiques Résumé : Facial imaging and quantitative image analysis of facial skin features, especially of those features associated with aging and beauty such as wrinkles and dark spots, are essential and routine in cosmetic science and aesthetic dermatology. However, these methods and services are reserved primarily for the research lab, clinic, spa or department store counter. Toward the goal of bringing this technology into the home, we have developed a web-based imaging system whereby facial images, captured using ordinary digital cameras and with modest attention to lighting, resolution and zoom, can be uploaded to a central server and analyzed for the severity of facial wrinkles and dark spots. Photographic standardization, essential for reproducible and quantitative image analysis, is aided by a universal headband worn during image capture. Functioning as an internal reference standard, color ships and other graphic information on the headband are employed by server-based software to verify image quality and make corrections for variation in lighting, resolution, and registration prior to image analysis. In this paper, we compare the web-based system's precision, accuracy, and linearity to a benchmark facial imaging system (VISIA). We also assess the system's utility for tracking changes in facial skin hyperpigmentation before and after dermatologic treatment.

VaselineIndex. décimale : 667.2 Colorants et pigments Résumé : Fingerprinting and DNA comparisons are the most commonly used methods in criminal investigations. However, lip prints can also be used as a supplementary tool because of the uniqueness of morphological patterns. A lip print not only can be used for personal screening by its pattern, it also carries genetic information that enables personal identification. Nowadays, there are various kinds of plants that are used for biological and histological staining due to an increasing market value associated with their application and sustainability. This study assessed the ability of natural dye extract to develop latent lip print contrast images and to preserve DNA for short tandem repeat analysis. Results revealed that roselle extract showed potential for the development of vaseline-treated lip print contrast images on bond paper. Moreover, when roselle extract-stained paper was compared with unstained paper, short tandem repeat profiles were not affected. Therefore, such dyes could be utilised for the development of latent lip print contrast images and their application could be extensively used to establish a personal identification database for reference in criminal investigations.

shampooingsIndex. décimale : 668.5 Parfums et cosmétiques Résumé : For many women, hair colour is an important part of their beauty routine. Women have been using a variety of approaches to cover up their greys. Today, hair colour is used to generate a myriad of results ... from achieving flawless coverage from root-to-tip to creating vibrant rainbow tresses. As women age, the desire to look younger by covering grey hair (a sign of ageing) has been the main driver for using permanent (oxidative) hair colour. The appeal of the vibrant, bold, fashion hair colours has driven the use of temporary and semi-permanent hair colours. But colour fading is a concern for both permanent and temporary/semi-permanent hair dyes, as they tend to fade fast, and often off-shade.
