Skin health and pollution are directly related to each other. People living in cities with less pollution tend to have better skin than those living in polluted places. Another factor that determines the health of your skin is climate. If you are planning to move to a new city, make sure to check the pollution rate and the climatic conditions of the place.

Here is a list of the four best cities that help maintain healthy skin.

1. Portland, Oregon
The climate in Portland is great for your skin. Since it is raining most of the time, people don’t get extreme sun exposure. Portland is surrounded by nature that keeps the city free of pollution. Pollution causes inflammation to the skin and speeds up the aging process. The air is clean and free of pollution. Portlanders are less likely to suffer from sunburn. They also are less likely to smoke. The combination of a clean environment, less sun, and no pollution makes it a great city for your skin.

2. San Francisco, California
Second on the list is San Francisco. The city has zero ozone days and a high density of dermatologists per capita. Residents of the city are quite particular about their skin health. They use sunscreen and moisturizers daily. San Francisco has a very low skin cancer death rate. If there is any pollution in the air, it is cleaned out by the fog. Most dermatologists receive their training at UCSF and Stanford. The city has sophisticated skincare facilities, which makes it easier for people to maintain their skin health.

3. Seattle, Washington
Seattle is known for its cloudy weather. The sun shines 47% of the time in Seattle. Lack of sun exposure is great for healthy skin. Even though it rains most of the time, the sun can be quite harsh during the day. Residents wear a good amount of sunscreen and moisturizer. Low pollution levels in the city allow your skin to breathe. The city also has very few ozone days. This is another indication that the climate is beneficial for your skin. In comparison to other cities, Seattle has low levels of skin threats.

4. Honolulu, Hawaii
Skin health and pollution go hand-in-hand. According to Julie Kenner, MD, founder of Kenner Dermatology Center in Hawaii, free radicals in pollution can cause oxidative damage to the skin. They cause changes to the skin’s DNA and worsen the effects of UV rays on the skin. The capital of the Aloha State has zero high-ozone days. It may come as a shocker to some, but Honolulu also has the lowest rate of air-particle pollution in the country. Since the sun is always out, residents are more vigilant about sun protection, making it a great city for healthy skin.
