Abstract: Exposure to pollution can cause oxidative stress, premature ageing, inflammation, and diseases. Since most of us are exposed to pollution, protection is important. This can be achieved through skin protection or through protection with respect to food and food supplements. There is a wide range of products on the market with anti-pollution claims. However, it is important that these claims are thoroughly validated by proper efficacy testing. When skin cells are exposed to pollution factors, changes in a number of skin properties can be observed, such as lipid composition, lipid and protein oxidation, pH, sebum secretion rate, oxidative stress, inflammation markers, and collagen and elastin levels. These can be measured and used as markers to verify anti-pollution claims. In the present review, we summarize some of the most important in vitro and in vivo tests that are used to determine if an ingredient or formulation has anti-pollution efficacy.
