Detailed answer

Air pollution releases harmful particles, such as PM2.5 and toxic gases, that can penetrate the skin and cause oxidative stress. This leads to the production of free radicals, which damage collagen and elastin fibers in the skin, resulting in wrinkles, fine lines, and sagging. Air pollution also triggers inflammation, disrupts the skin's natural barrier function, and increases the risk of skin conditions like acne and eczema. Moreover, pollutants can induce the formation of dark spots and uneven skin tone. To protect the skin from air pollution, it is important to cleanse thoroughly, use antioxidants, and wear sunscreen daily.
