Background
In recent years, with the continuous deterioration of the environment, air pollution has become an important factor that endangers human health, such as PM2.5, which is a pollutant particle with an aerodynamic equivalent diameter of 2.5 μm or less. The particles are not only a pollutant, but also a carrier of toxic substances such as heavy metals, polycyclic aromatic hydrocarbons and the like, and have great damage to the skin. Air pollution has become an important factor in exogenous skin aging. Therefore, research on the influence of air pollution on skin is carried out, and research on anti-pollution skin care products is particularly important.
Contaminants in the air, when in contact with the skin, can cause a decrease in the viability of skin cells and can cause toxic damage to keratinocytes. Such damage can lead to visible changes in the skin, such as dryness, redness, swelling, wrinkles, and the like. And the keratinocytes release inflammatory factors IL-1 alpha and TNF-alpha, activate NF- κB signaling pathway, generate a large amount of inflammatory factors such as IL-8, COX2, PEG2, VCAM-1 and the like, and further cause immune cell recruitment and migration, vascular reactions such as vasodilation, permeability change and the like, and finally cause skin inflammation acute phase reactions of redness, swelling, pain and itching. The skin tolerance is poor and the skin is sensitive after long time. In addition, reduction of thiol groups in skin, which increases tyrosinase activity, may cause skin pigmentation, and cause skin aging, due to reduction or partial removal of thiol groups in skin by inflammatory reaction.
In the current commercial cosmetics, only a few products have anti-pollution effects, the anti-pollution effects are mainly concentrated on the aspect of cleaning skin, the effects are relatively single, various pollution sources cannot be comprehensively resisted, and the anti-pollution effects are not obvious.
