Effects of Air Pollution on Cellular Senescence and Skin Aging

Effects of Air Pollution on Cellular Senescence and Skin Aging

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 emerging role of nanotechnology in skincare

The emerging role of nanotechnology in skincare

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...

Skin care and rejuvenation by cosmeceutical facial mask

Skin care and rejuvenation by cosmeceutical facial mask

Research Summary: Skin health is an important aspect of aesthetics. Dermatologists and scientists continually strive to develop novel methods and materials to achieve healthy skin. Facial cosmetics help keep skin moisturized and remove sebum to maintain proper skin health. The use of suitable cosmetics according to one's facial skin type results in healthier skin. Among these cosmetics, facial masks are the most prevalent products utilized for skin rejuvenation.Facial masks are divided into four groups: (a) sheet masks; (b) peel‐off masks; (c) rinse‐off masks; and (d) hydrogels. Each type offers specific advantages for particular skin types based on the ingredients used....

Contribution of Topical Antioxidants to Maintain Healthy Skin—A Review

Contribution of Topical Antioxidants to Maintain Healthy Skin—A Review

Research Summary: The skin is constantly exposed to various environmental stresses, particularly the damage caused by pollution and ultraviolet (UV) radiation. As a consequence, the outer layer of the skin can be negatively impacted by the harmful influence of some of its surface components. The mechanisms involved in the degradation processes promoted by UV radiation are driven by the direct absorption of radiation via cellular chromophores, the formation of excited states, and the consequent chemical reactions. In addition, photosensitization mechanisms occur, in which UV light is absorbed by sensitizers that become excited, leading to the formation of reactive oxygen species...
