It’s our last installment on the worst cities in the country for your skin. TotalBeauty.com conducted a study to find which cities are most harsh on our skin and we’ve taken the liberty of adding our commentary. Take a look at the five worst to see if your city made the unfortunate list.

#5: Phoenix, Arizona: “But it’s a dry heat!” Whoever came up with that never knew the wrath of severely dry skin. Without the hydration it needs, the lipid layer depletes and skin dries out as a result. To make up for the moisture deficit, Dr. Zein Obagi recommends drinking more than 8 glasses of water daily and avoiding hot water like the plague.

#4 Las Vegas, Nevada: Your skin’s luck runs out fast in this city. Las Vegans endure triple digit temperatures, a dry climate and high smoking rates, but its stress level is so high it’s stressful. Rosacea, acne, psoriasis — all of them flare up under stress. Meditate, take up yoga, count to 10. For the sake of your skin, Las Vegas, relax.

#3 Pittsburgh, Pennsylvania: Take away the pollution and you still have the tanning beds. Take away the tanning beds and you still have 20 percent of the city puffing away. No need to fear, Pittsburgh. Dr. Zein Obagi’s daughter, Dr. Suzan Obagi, is assistant professor at the Cosmetic Surgery and Skin Center at University of Pittsburgh. When she’s not making women look younger, she’s dermatologist to the Pittsburgh Steelers. Consider her your saving grace!

#2 Houston, Texas: Ninety percent humidity and high ozone pollution prove you can’t mess with Texas, but Texas — Houston specifically — can mess with your skin all it wants. Pollution is one thing, but high ozone pollution will make your skin more susceptible to burns and damage layers of tissue. Three words: Ess. Pea. Eff.
