Detailed answer

Air pollution can disrupt the natural protective barrier of the skin, leading to various skin issues. Pollutants such as particulate matter, heavy metals, and oxides can penetrate the skin and cause oxidative stress, inflammation, and damage to the lipid bilayers of the stratum corneum. This disruption weakens the skin's defense mechanism, making it more susceptible to moisture loss, dehydration, irritation, and accelerated aging. Air pollution can also increase the production of free radicals, leading to collagen breakdown, uneven skin tone, and the development of fine lines and wrinkles. Additionally, pollutants can trigger the activation of enzymes that degrade skin proteins, further compromising the skin barrier function. It is crucial to protect the skin from air pollution by using effective skincare products, practicing regular cleansing, and applying a barrier-forming moisturizer with antioxidants.
