“…Similar results were presented by A.I. Nicoara et al [ 39 ], who observed that silver enhancement increases the SPF significantly, especially when compared to the pristine samples. For the emulsion with the model physical filter, which was TiO 2 , the time before the application was 29 min; after application, the time of natural sun protection was extended by 4 min, while after water bathing, a similar value was recorded as before the application of the cosmetic, which was 30 min on average.…”

The following work describes the synthesis of new physical filters based on TiO2/SiO2 and TiO2/Ag nanostructures. Titanium dioxide nanoparticles (TiO2 NPs) were applied as control material and a popular physical UV filter. The advantage of using materials on the nanometer scale is the elimination of the skin whitening effect that occurs when using photoprotective cosmetics containing titanium dioxide on a macro scale. In addition, the silica coating makes the material less harmful, and the silver coating enriches the material with antibacterial properties. Nanoparticles and nanostructures have been characterized by Energy Dispersive X-Ray Analysis (EDX), the Scanning Electron Microscope (SEM), Transmission Electron Microscopy (TEM), and Fourier-Transform Infrared Spectroscopy (FT-IR) methods. Due to the use of physical filters in anti-radiation protection cosmetics, water-in-oil (W/O) emulsion has been prepared. All cosmetic formulations have been tested for stability. The sun protection research with the Sun Protection Diagnostic SP37 was carried out. These studies made it possible to determine the natural sun protection time and to compare the synthesized materials. Furthermore, one of the most important parameters when describing this type of cosmetic is water resistance, which has also been measured. The results show that the new type of material of TiO2/Ag used as a new physical filter in emulsion W/O shows the best sun protection compared with other obtained nanomaterials. It is most likely due to the improved optical properties of the combination of noble metals, for example, silver with TiO2.

“…The skin barrier is the first line of defence against environmental pollutants. 1 The epidermis is the outermost layer of the skin and is damaged by long-term exposure to environmental pollutants, resulting in oxidative stress and skin ageing. 2 One of epidemiological studies have shown that air pollution, including exposure to particulate matter (PM), sulphur dioxide and nitrogen dioxide, is closely related to the incidence of skin diseases.…”

Particulate matter (PM2.5) is an environmental pollutant causing skin inflammatory diseases via epidermal barrier damage. However, the mechanism and related gene expression induced by PM2.5 remains unclear. Our aim was to determine the effect of PM2.5 on human skin tissue ex vivo, and elucidate the mechanism of T helper 17 cell‐related inflammatory cytokine and skin barrier function. We verified the expression levels of gene in PM2.5‐treated human skin tissue using Quantseq (3′ mRNA‐Seq), and Gene Ontology (GO) terms and protein–protein interaction (PPI) networks were performed. The PM2.5 treatment significantly enhanced the expression of Th 1, 2, 17 and 22 cell‐related genes (cut‐off value: │1.2 │ > fold change and p < 0.05). Most of all, Th17 cell‐related genes are upregulated and those genes are associated with skin epidermal barrier function and Aryl hydrocarbon receptor (AhR), a xenobiotic receptor, pathway. In human keratinocyte cell lines, AhR‐regulated genes (e.g. AhRR, CYP1A1, IL6 and IL36G), Th17 cell‐related genes (e.g. IL17C) and epidermal barrier–related genes (e.g. SPRR2A and KRT71) are significantly increased after PM2.5. In the protein level, the secretion of IL‐6 and IL‐36G was increased in human skin tissue following PM2.5 treatment, and the expression of SPRR2A and KRT71 was significantly increased. PM2.5 exposure could ruin the skin epidermal barrier function via AhR‐ and Th17 cell‐related inflammatory pathway.

“…All above-mentioned health issues are partly related to diets in healthy populations [ [18] , [19] , [20] , [21] , [22] ]. Constipation is inversely associated with the Japanese traditional diet, including a high intake of rice, miso soup, and soybean with limited intake of bread and confectionaries [ 19 ].…”
