In the warmer months, we can say goodbye to pesky cold-weather skin problems like pasty, dry skin and chapped lips. But summer brings with it a host of different skin woes, like bug bites, rashes and, perhaps worst of all, sunburn.
"We all know about sunscreen," Jessica Wu, M.D., author of "Feed Your Face" and skin and beauty expert for Daily Glow tells The Huffington Post. "[But there are] less obvious links to skin health."
To help draw attention to some of those links, Wu and Daily Glow analyzed 55 of the biggest cities across the United States to determine "where skin is most likely to shine and which locations need to clear up their complexion," according to a press release.
Each city was evaluated based on a number of criteria established by Wu and the team, including number of dermatologists per capita, skin cancer rates, climate, air pollution, tanning beds per capita, and percentage of adults of exercise regularly and smoke.
"Smoking is bad for your skin in a lot of different ways," Wu tells HuffPost. Lighting up reduces the amount of oxygen in the blood, decreasing circulation by up to 40 percent, she says, so smokers often have a worse complexion. There's also "the mechanical effect" of smoking, she says. Smokers are likely to have wrinkles on the lips and around the mouth from all that puckering.
Using data from the American Academy of Dermatology, the CDC, the Census Bureau, the American Lung Association and more, Daily Glow has ranked the 55 cities from best to worst. Granted, you're not likely to pack up and move just because your place of residence happens to land on the bottom half of the list. But there are a few simple things you can do to make any environment even slightly more skin-healthy, says Wu.
First, think about what you're doing when you're outside, and how it relates to your sunscreen, she says. If you're sweating a lot or you're in water, you need extra protection. Also, take altitude into consideration. In more mountainous areas you'll be exposed to more UV rays, she says, so be extra careful about reapplying sunscreen, especially if you have light eyes, light skin and fair hair, she says.
