Detailed answer

Air pollution, such as fine particulate matter (PM2.5) and volatile organic compounds (VOCs), can have detrimental effects on the skin, especially for those with redness or rosacea. These pollutants can penetrate the skin and cause inflammation, leading to increased redness and irritation. Additionally, air pollution can disrupt the skin barrier function, making it more susceptible to external irritants and exacerbating rosacea symptoms. It is important for individuals with these skin concerns to take appropriate measures, such as using antioxidant-rich skincare products, wearing protective clothing, and avoiding high pollution areas, to minimize the negative impact of air pollution on their skin.
