5 Surprising Things That Age You
What it ages: Your skin
The science: The air you're exposed to on the highway is no friend to your complexion. Traffic-related pollution can lead to age spots, according to a review in the Journal of Investigative Dermatology, while another review in Frontiers in Environmental Science found that pollution contributes to overall skin aging, plus other problems like acne, eczema and psoriasis.
What you can do: Until someone comes up with a way to make a long commute shorter (get on that, scientists), these tips should help. First, if you drive an older car, roll your windows down instead of up when you're sitting in traffic. (With an older air-filter system, you'll just breath in your car's own exhaust if you keep them up). Second, apply a topical antioxidant product to your face, neck and chest in the morning to help protect your skin from environmental pollution.
