Smog is a type of air pollution that is formed when sunlight reacts with certain pollutants in the air, such as carbon monoxide, nitrogen oxides, and volatile organic compounds. It can be harmful to the skin in a number of ways.
First, smog can cause irritation and dryness of the skin. The pollutants in smog can strip the skin of its natural oils, leading to dryness and a feeling of tightness. In addition, smog can irritate the skin, causing redness, itching, and even rashes.
Second, smog can accelerate skin aging. The free radicals in smog can damage the skin cells, leading to the development of fine lines, wrinkles, and age spots.
Finally, smog can increase the risk of skin cancer. The UV radiation in smog can damage the DNA in skin cells, increasing the risk of skin cancer. It is important to protect your skin from smog by using sunscreen and wearing protective clothing when you are outside, especially on days when smog levels are high.
In summary, smog can cause irritation, dryness, and accelerated skin aging, as well as increase the risk of skin cancer. It is important to protect your skin from smog by using sunscreen and wearing protective clothing.
