Description

technical field [0001] The present invention relates to a cosmetic. Background technique [0002] The ultraviolet rays radiated from the sun to the ground include UV-B with a wavelength of 290nm-320nm and UV-A with a wavelength of 320nm-400nm. 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 sunscreen is very necessary. [0003] Generally, commercially available sunscreens are heavy in texture and have added some chemical sunscreens. Applying heavy 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 causes skin symptoms.
