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 interventions proposed to prevent or mitigate their effects on the skin.
