Detailed answer

Air pollution, particularly exposure to pollutants like particulate matter and ozone, can impair collagen production in the skin. These pollutants generate free radicals that promote oxidative stress, leading to the breakdown of collagen and inhibiting collagen synthesis. This can result in accelerated skin aging, including the appearance of wrinkles, sagging, and loss of elasticity. Additionally, air pollution can also contribute to inflammation and skin barrier dysfunction, further compromising collagen production and overall skin health.
