What Dermatologists Know About Wrinkles That You Don't
Pollution is another culprit in aging, says Peredo. In fact, a 2016 study from German researchers looked at the impact of traffic-related air pollution on skin quality. This type of pollution spews nitrogen dioxide into the air, exposure to which was associated with a greater number of wrinkles on the cheeks of women, particularly women older than 50, the researchers found. Peredo recommends patients use sunscreens that are formulated with antioxidants that act like a shield against air pollution, such as Alastin's HydraTint Pro Mineral Broad Spectrum Sunscreen SPF 36, which contains free-radical scavengers like algae and tea extracts. Eating foods rich in antioxidants, such as berries, leafy greens and tomatoes, is also important for blocking the free radicals from pollution and UV rays that can lead to wrinkles.
