The standard D65 illuminant and remove specular reflection mode were selected, and the samples were measured perpendicular to the UltraScan VIS lens. Each sample skin color, three different positions of the peel sample were analyzed. Six samples per group were measured to minimize the experimental ...
proteins, and lipids by generating intracellular chemical intermediates such as reactive oxygen species (ROS). This type of UV radiation causes mutagenesis in eukaryotic cells, photoageing and other skin disorders2. In contrast, UV-B (315–280 nm) radiation...
anthocyanins are commonly found in epidermal cells in petals and in the subepidermal cells of leaves. On the other hand, carotenoids are commonly located in the plastids and vacuoles via plastid-vacuole interactions
The dermal levels of carotenoids can be measured noninvasively by reflection photometry, which was used to follow 尾-carotene levels in skin after supplementation.doi:10.1002/1097-0231(20001230)14:24<2408::AID-RCM181>3.0.CO;2-KWilhelm Stahl...
