Role of Natural Antioxidants in Anti-Pollution Skincare: A Comprehensive Review

Pollution is becoming increasingly evident owing to rapid urban development and an increase in the number of industries that produce pollutants. Various pollutants, such as particulate matter, gases, and metals, can penetrate the skin and cause organ damage through free radical generation via various methods, including oxidation, inflammation, ageing, and uneven melanin distribution. Consequently, the need for anti-pollution agents, particularly antioxidants that eliminate free radicals, has increased significantly. This review describes the mechanisms of action of five antioxidants, including green tea, turmeric, vitamin C, vitamin E, and butterfly pea flower, in protecting the skin against pollutants. Articles were found in various databases, such as PubMed, Google Scholar, and Science Direct, involving experiments conducted both in vitro and in vivo in humans. Hence, these antioxidants have protective properties and can be used independently or in combination to enhance the efficacy of anti-pollution products.
