We love to keep our melanin poppin', but there are some cities that won't let our skin be great.
A new study by experts in air purifiers, dehumidifiers and humidifiers at HouseFresh has revealed the best and worst cities for keeping skin healthy in the United States.
Researchers went from city to city measuring air pollution, hard water and ultraviolet light—all factors that can impact your skin.
"Skin health is something the U.S. takes very seriously, spending over $18 billion on skincare in 2021 alone—more than any other country in the world," James Booth, the managing editor of HouseFresh, tells Newsweek. "With environmental factors such as air pollution still affecting more than 40 percent of people living in the country, the HouseFresh team wanted to find out the effects this is having on your skin and what can be done to prevent further damage."

Researchers created the index score for 328 cities with a metric (air pollution, UV light and water hardness) that was given a weight of 33.33 to add up to 100 in total.
Cities that had cleaner air were rewarded higher scores, while those with less UV radiation and softer water received lower scores for factors like high pollution levels and more UV radiation.
"Studies have shown that air pollution, hard water and UV levels have harmful effects on our skin. For example, too much exposure to UV light can cause skin cancer and other skin conditions like solar elastosis," Booth says.
"Air pollution can cause a variety of health problems when inhaled but it can also cause skin to age prematurely. Meanwhile, bathing in hard water can worsen problems such as eczema and psoriasis."

How to protect your skin
Check out these tips from HouseFresh on protecting your skin from environmental damage:
- Use broad-spectrum sunscreen SPF 30 or higher every day: UV light exposure increases your risk of developing skin cancer and prematurely ages the skin by causing wrinkles and age spots.
- After bathing, moisturize your skin while it's damp: Research has indicated a link between hard water and the worsening or development of skin conditions like eczema.
- Wash your face with high-quality cleanser at the end of the day: Particular matter (PM) is the name given to solid or liquid particles in the air (for example, smoke or dust) that collect air pollution. These particles can become attached to your skin when you're out and about.
