The present invention relates to a system and a method for measuring the ultraviolet ray protection of a cosmetic material, and according to one embodiment of the present invention, the system for measuring the ultraviolet ray protection of a cosmetic material comprises: a light source for emitting light including ultraviolet bands; a transparent plate through which the lights emitted from the light source pass, and having one surface to which a cosmetic material to be tested is applied; a wavelength conversion film, which changes, to a predetermined size, the light, of an ultraviolet band, of the light having passed through the transparent plate and makes the same pass therethrough; and a photosensitive sheet, which accommodates the light having passed through the wavelength conversion film and has a photosensitive property for light of UVA and UVB bands among the ultraviolet bands. La présente invention concerne un système et un procédé de mesure de la protection contre les rayons ultraviolets d'un matériau cosmétique, et selon un mode de réalisation de la présente invention, le système de mesure de la protection contre les rayons ultraviolets d'un matériau cosmétique comprend : une source de lumière permettant l'émission d'une lumière comprenant des bandes ultraviolettes ; une plaque transparente à travers laquelle passent les lumières émises par la source de lumière et présentant une surface sur laquelle est appliqué un matériau cosmétique à tester ; un film de conversion de longueur d'onde, qui change, vers une taille prédéterminée, la lumière d'une bande ultraviolette de la lumière ayant traversé la plaque transparente et la fait passer à travers cette dernière ; et une feuille photosensible qui reçoit la lumière ayant traversé le film de conversion de longueur d'onde et possède une propriété photosensible pour la lumière des bandes UVA et UVB parmi les bandes ultraviolettes. 본 발명의 화장료의 자외선 차단력 측정 시스템 및 측정 방법에 관한 것으로서, 본 발명의 일 실시예에 따른 화장료의 자외선 차단력을 측정하기 위한 시스템은, 자외선 대역을 포함하는 광을 방출하는 광원, 상기 광원으로부터 방출되는 광이 통과하며, 일 면에 테스트 하고자 하는 화장료가 도포되는 투명 플레이트, 상기 투명 플레이트를 통과한 광 중에서 자외선 대역의 광을 일정한 크기로 변환하여 통과시키는 파장 변환 필름, 및 상기 파장 변환 필름을 통과한 광을 수용하여, 자외선 대역 중 UVA 및 UVB 대역의 광에 감광성을 갖는 감광 시트를 포함한다.
