Human skin is exposed daily to various environmental factors, including air pollutants and ultraviolet (UV) light. Air pollution is recognized as a significant environmental risk to human skin, promoting aging and inflammation that lead to skin disorders, wrinkles, and pigmentation issues. Moreover, components of air pollution can synergize with UV light, amplifying skin damage. Despite this, the role of air pollution in modulating cellular senescence in skin cells and its contribution to skin aging remains poorly understood. This review summarizes the current knowledge on air pollution components, their role in cellular senescence and skin aging, and the therapeutic and cosmetic...

The increase in air pollution over the years has significantly impacted human skin. The skin is exposed to ultraviolet radiation (UVR) and environmental air pollutants such as polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), oxides, particulate matter (PM), ozone (O₃), and cigarette smoke. Although human skin functions as a biological shield against pro-oxidative chemical and physical air pollutants, prolonged or repetitive exposure to high levels of these pollutants can have profound negative effects. Such exposure has been linked to skin aging, as well as inflammatory and allergic skin conditions, including atopic dermatitis, eczema, psoriasis, and acne. Among the most...

Research Summary: The role of cosmetic products is rapidly evolving in our society, with their use increasingly seen as an essential contribution to personal wellness. This suggests the necessity of a detailed elucidation of the use of nanoparticles (NPs) in cosmetics. The aim of the present work is to offer a critical and comprehensive review discussing the impact of exploiting nanomaterials in advanced cosmetic formulations, emphasizing the beneficial effects of their extensive use in next-generation products despite a persisting prejudice around the application of nanotechnology in cosmetics. The discussion here includes an interpretation of the data underlying generic information reported...

Research Summary:  Natural substances have traditionally been used in skin care for centuries. There is now an ongoing search for new natural bioactives that not only promote skin health but also protect the skin against various harmful factors, including ultraviolet radiation and free radicals. Free radicals, by disrupting defense and restoration mechanisms, significantly contribute to skin damage and accelerate aging. Natural compounds present in plants exhibit antioxidant properties and the ability to scavenge free radicals. The increased interest in plant chemistry is linked to the growing demand for plant materials as natural antioxidants. This review focuses on aromatic and medicinal...
