A kind of microcapsule structure with what sun-screening agent includes a hollow shell and a suntan lotion core. The material of the hollow shell contains polyvinyl alcohol (polyvinyl alcohol),And it surrounds and defines an internal capacity room； The suntan lotion core is accommodating what room,And the effect of containing sunscreen products composition,Thereby,The microcapsule structure of the utility model sun-screening agent utilizes the characteristic of material,When ambient temperature rises or is irradiated with ultraviolet radiation,The shell layer surface can generate many holes,And make the composition in the suntan lotion core by slowly releasing in the grade holes,Therefore when the utility model is coated with what skin,The composition that can effectively extend in sunscreen products stops the time of what skin surface,It can increase sun-proof effect and reduce user and mend the number wiped.一種用於防曬劑之微膠囊構造，包含一中空殼層，及一防曬液核。該中空殼層之材質含有聚乙烯醇(polyvinyl alcohol)，且包圍界定一內部容室；該防曬液核是容置於該容室，且含有防曬品的功效成份，藉此，本新型防曬劑之微膠囊構造利用材質的特性，在外界溫度上升或受到紫外線照射時，該殼層表面會產生許多孔隙，而使得該防曬液核當中的成份由該等孔隙中緩慢釋出，故將本新型塗佈於肌膚時，能有效延長防曬品中的成份停留於肌膚表面的時間，能增加防曬的效果並減少使用者補擦的次數。
