Smog looks bad, smells bad, and shamelessly makes metropolitan cities look crummy. Could this city works disaster also have the same marring effect on your skin?

According to AIRNow, a hybrid of government group that provides the public data on national air quality levels, Ozone is a major part of urban smog. Ozone can impair breathing, and cause coughing, throat irritation, and breathing discomfort. Plus, evidence suggests that ozone can lower resistance to respiratory disease like pneumonia, damage lung tissue, and aggravate chronic lung disease, like asthma or bronchitis.

Now, pioneering studies on ozone could add oxidative skin damage to smog’s growing list of ill health effects. An investigation in the International Journal of Cosmetic Science mimicked typical smog exposure levels on human skin cells. Researchers noticed that ozone exposure significantly reduced vitamin E concentrations on the skin cells by 70%.

To help counter the oxidative stress that ozone exerts on the skin, scientists tested the potential of various antioxidants like vitamin C as an ozone
protector. The results published in Toxicology in Vitro concluded that raw vitamin C did
prevent ozone induced cellular damage to skin cells.

Ironically, while vitamin C may protect against ozone induced skin damage,
a study in Free Radical Biology and Medicine found that ozone exposure could actually
reduce amounts of vitamin C and vitamin E in the upper layers of mice
skin.

You can reduceozone’s stress on the skin by using vitamin C and E. Today even
the most inexpensive skin moisturizers contain some quantity of vitamin C (ascorbic
acid) and Vitamin E (alpha-tocopherol). To combat the effects of ozone nutritionally,
consume food sources like fruits and vegetables for vitamin C while enjoying nuts and
nut-based oils for vitamin E.
