reflectionmeasurementscarrotjuicehemoglobinOptischeReflektionsmessungenKarottensaftHämoglobinObjective: To increase the carotenoid concentration in skin by drinking carrot juice to generate an optical response and to determine an in vivo absorption spectrum of the carotenoids and compare it to ex vivo ...
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...
Photooxidative damage is suggested to be involved in the pathobiochemistry of several diseases affecting the skin and the eye, and carotenoids may protect light-exposed tissues. Lutein and zeaxanthin are the predominant carotenoids of the retina and are considered to act as photoprotectants preventing...
When the incident angle of the polarized light exceeds the critical value, the total reflection is achieved, and the signal of the reflected light is converted either to a resonance angle or wavelength, which is identified by the detector attached to the equipment. (Prabowo et al., 2018, ...
β-Carotene, β-cryptoxanthin, and α-carotene are pro-vitamins A [20,21], and carotenoids in general have antioxidant [20,22], anticancer [21,23], anti-inflammatory, antidiabetic, neuroprotective, and anti-obesity effect [22]. They protect skin, tissue, and cells from environmental toxins ...
