Studies show that environmental factors can cause major changes in both the structure and biophysical properties of the skin, leading experts to deem air pollution as a “factor of aging.” When your skin is constantly exposed to these damaging factors over an extended period of time, it becomes more vulnerable to free-radical damage.
Excessive free-radical exposure harms the skin by damaging DNA and cell membranes that help keep skin intact, plump and firm. When the membranes are destroyed or disrupted, skin cells no longer perform their normal functions, like processing nutrients and eliminating waste.
Pollution can also trigger inflammation and activate the enzymes that destroy collagen and elastin, resulting in thin, wrinkled, rough, blotchy skin.
