The Impact of Environmental Factors on Skin and Tissue Ageing

Introduction: Ageing is a natural biological process that affects every living being. With the passing of years, due to both internal and external factors, the skin's functions gradually weaken, and its regenerative processes slow down. This manifests as a decrease in elasticity, discoloration, and other visible signs of ageing. Factors such as sunlight, air pollution, smoking, alcohol consumption, diet, and physical activity play a crucial role in determining the rate of the ageing process. The aim of the study: The aim of this article is to review the ageing process of the skin and other tissues, along with the impact of environmental factors. The paper focuses on mechanisms like oxidative stress, inflammation, and the decline in collagen and elastin production. Material and Methods of Research: The literature was collected through searches in the PubMed, Google Scholar databases, and references from the initially retrieved articles with keywords including “skin aging” “environmental factors” and “oxidative stress”. Conclusion:The ageing process encompasses structural and functional changes in the skin and other tissues, as well as alterations at the cellular and molecular levels. With advancing age, collagen and elastin production decreases, resulting in reduced elasticity, firmness, and resilience. Additionally, diminished bone and fat volume weakens structural support, leading to sagging skin and the development of fine wrinkles. The facial contour changes, and the wound-healing process becomes slower. Both genetic and environmental factors influence the ageing process. Environmental contributors such as UV radiation, air pollution, smoking, alcohol consumption, and an unhealthy diet exacerbate oxidative stress, thereby accelerating skin ageing. Conversely, adopting a healthy lifestyle—including regular physical activity, a diet rich in antioxidants, and avoiding excessive sun exposure—can help mitigate these effects and slow the ageing process.
