Detailed answer

Pollution can have detrimental effects on the skin, especially for those with uneven skin tone. When exposed to pollutants, the skin can become inflamed, leading to redness and irritation. Additionally, pollutants generate free radicals, which cause oxidative stress and damage the skin's cells. This oxidative stress can disrupt the normal processes of melanocytes, leading to hyperpigmentation and further exacerbating uneven skin tone. To protect against pollution, it is important to cleanse the skin thoroughly to remove pollutants, use antioxidant-rich skincare products to neutralize free radicals, and consider using physical barriers like sunscreen or protective clothing when in highly polluted environments.
