Pollution can have negative effects on skin health in several ways. Air pollution can lead to the formation of free radicals on the skin, which can accelerate the aging process and cause damage to skin cells. Pollutants such as diesel exhaust particles and heavy metals can clog pores, leading to acne and other skin conditions. Additionally, pollution can cause inflammation and irritation, making the skin more prone to sensitivity and redness. To minimize the impact of pollution on skin health, it is important to cleanse the skin regularly, use antioxidant-rich skincare products, and protect the skin with a barrier such as sunscreen.
