Excessive exposure to these two types of ultraviolet rays will cause sunburn to the skin. Various cells in the dermis release inflammatory mediators such as histamine, 5-hydroxytryptamine, and kinin, which dilates blood vessels and increases permeability in the dermis. Generally manifested as erythema, edema, blisters and pigmentation, desquamation and so on. Therefore, the application of tea polyphenol sunscreen is very necessary. [0003] Generally, tea polyphenol sunscreens on the market are heavy in texture and have added some chemical sunscreens. Applying thick tea polyphenol sunscreen in hot summer will cause discomfort to the skin, and the use of some chemical sunscreens also increases the chance of skin allergies and even ca...
