According to the World Health Organization (WHO), 92% of the world’s population lives in places with too much air pollution.[1] In addition to affecting people’s health, pollution causes visible damage to skin. This article will help you learn how to boost your natural defenses against free radicals and reduce the effects of oxidative stress, such as the premature aging of skin.

What is oxidative stress?

Free radicals are unstable molecules from the oxygen we breathe and are essential to life and to health. However, when there are too many of them in our bodies, they damage our healthy cells. This is called oxidative stress, a natural phenomenon that keeps the body from defending itself adequately against inner and outer attacks.

Causes of oxidative stress: Environment and lifestyle

Pollution outdoors and indoors (air fresheners, scented candles, etc.)
Exposure to blue light (computer screens, cellular phones, tablets, etc.) and ultraviolet light
Chronic stress
Excessive alcohol consumption
Smoking
Imbalanced diet (high in fats and low in antioxidants)
Ingestion of pesticides and food additives
Sedentariness or over-exercising

Genes and aging also contribute to oxidative stress.

What does oxidative stress do to your skin?

Oxidative stress has been linked to many chronic illnesses, including diabetes. This phenomenon also has a major impact on skin, since it causes premature aging.
