Pollution & Dark Spots
Did you know that constant exposure to traffic-related air pollution can contribute to dark spots? Often, when we think about what causes hyperpigmentation, we think of sun damage, genetics, and aging. But research shows that pollution also increases your risk. According to a study, exposure to an air pollutant like nitrogen dioxide was associated with more dark spots on the cheeks. One way to safeguard yourself from this kind of damage is to use products formulated with antioxidants and to apply broad-spectrum sunscreen daily to prevent new spots from forming.
