Living in the city can be stressful to the skin: high concentrations of pollutants in the air will stress your skin through the production of free radicals. Free radicals are high energy molecules that are missing an electron and will go about starting chain reactions and destroying molecules in their search for the missing electron. The molecules they stole electrons from will become ROS* themselves and continue a chain reaction. What we see in a polluted city is a “cloud” of very fine particles floating in the air, and the air smells strange.
