Detailed answer

Exposure to pollutants in the air, such as toxins, dust, and smoke, can have a negative impact on the skin, potentially leading to sallow or dull complexion. These pollutants can clog the pores, impede the natural cell turnover process, and cause inflammation, resulting in a lackluster appearance. Additionally, pollutants can increase oxidative stress and free radical damage, which further contribute to a sallow complexion. It's important to cleanse the skin thoroughly and use protective measures like antioxidants and sunscreen to minimize the effects of pollutants on the skin.
