摘要
Ultraviolet(UV),ozone(O_(3)),and particulate matter(PM)in air pollutants in the external environment can induce skin aging through oxidative mechanisms such as free radicals,lipid peroxidation,and protein oxidation.Antioxidant cosmetics can be used to defend against oxidative damage caused by the external environment to the skin.In China,the claimed cosmetics need to be managed according to new efficacy cosmetics,but there are currently few reports on the evaluation methods for such new efficacy cosmetics.The efficacy evaluation methods of cosmetics with antioxidant mechanisms under UV,O_(3),and PM models were reviewed,and the skin damage caused by UV,O_(3),and PM were introduced.Suggestions for the application of each model in the efficacy evaluation of antioxidant cosmetics and raw materials were given to provide ideas for new efficacy claims and technical references for establishing a new efficacy evaluation system.
