Detailed answer

Environmental pollutants such as dirt, smoke, and chemicals can clog the pores and lead to the accumulation of debris on the skin's surface. This can result in the enlargement of pore size as the excess buildup stretches the pore walls. Additionally, pollutants can increase sebum production, further contributing to pore enlargement. These pollutants can also induce inflammation and oxidative stress, which can weaken the collagen and elastin fibers supporting the pores, causing them to appear larger. Protecting the skin from pollutants with proper cleansing, regular exfoliation, and the use of antioxidant-rich skincare products can help minimize the impact on pore size.
