Detailed answer

Air pollution contains harmful particles such as dust, smoke, and chemicals that can negatively affect dry skin. These particles can penetrate the skin and cause oxidative stress, leading to increased production of free radicals that damage the skin's natural moisture-retaining abilities. Additionally, air pollution can disrupt the skin barrier function by weakening the outermost layer of skin, allowing more moisture to evaporate. This can result in further dryness, flakiness, and irritation of the skin. To protect dry skin from the effects of air pollution, it is important to cleanse the skin thoroughly to remove these pollutants, use a moisturizer to replenish lost moisture, and consider using products with antioxidant properties to counteract the oxidative stress caused by pollution. Additionally, avoiding heavily polluted areas, using air purifiers indoors, and wearing protective clothing like scarves or hats can also help minimize the impact of air pollution on dry skin.
