Pollution causes the formation of free radicals. These molecules are produced as normal byproducts of cellular metabolism or by exposure to external sources such as X-rays, air pollution, cigarette smoking, and pesticides.

Free radicals have an unequal number of electrons, which creates a problem because electrons “like” to be paired. This means that free radicals will steal electrons from healthy molecules to stabilize themselves. Then what the molecule turns into a free radical and the chain reaction continues.

When your skin is exposed to these free radicals, it goes into a state called oxidative stress, and a prolonged state of oxidative stress accelerates skin aging process1.

In particular, it contributes to the loss of collagen and elastin fibers, which leads to fine lines, sagging and changes in texture. It can also cause dark spots for some.

But it is not only about these “signs of aging” – oxidative stress affects the main functions of the skin: oxidative stress is also involved in the reduction of barrier function, increased sensitivity and decreased moisture.

So, why your skin may be more sensitive and dry when air pollution is high.
