Detailed answer

Air pollution contains particles like dust, smoke, and chemicals that can penetrate the skin and trigger inflammation and allergies. These particles can disrupt the skin's natural barrier, leading to increased sensitivity, redness, and irritation. Prolonged exposure to air pollution can also worsen existing skin conditions such as eczema and acne. Additionally, pollutants can activate oxidative stress and generate free radicals, which accelerate skin aging and damage collagen and elastic fibers. To protect the skin, it is important to cleanse thoroughly, use products with antioxidants, and shield the skin with sunscreen and a physical barrier like a scarf or mask in polluted areas.
