Introduction
Concerns about adverse effects of air pollution on our health are on the rise worldwide. Main pollutants are particulate matter (e.g. from exhaust, smoke, pollen or ash), gaseous compounds (e.g. nitrogen and sulfur oxides or ozone), sunlight (e.g. UV- and blue light) and heavy metals. Not only the lungs but also the skin is exposed and this exposure can lead to e.g. signs of premature skin aging, damage to the skin barrier and cause pigmentation disorders. Pollution can exacerbate dry and irritated skin as well as increase skin impurities.
