散射反射分光光度法(DRS)是一种用于体内测量人体表防晒剂对UVA吸收作用的新技术。通过测定使用防晒剂前后皮肤光反射的变化而获得吸光度。根据吸光度,可以计算防晒剂在特定UV光源和生物学作用光谱下对UVA的防护效果。用DRS法体内检测了使用防晒剂前后和UV暴露前后皮肤对UVA的
Diffuse reflectance spectroscopy (DRS) is a new technique for in vivo measurement of UVA absorption by human skin sunscreens. Absorbance was obtained by measuring changes in skin light reflectance before and after the use of sunscreens. Based on the absorbance, the protective effect of the sunscreen agent on UVA can be calculated under a specific UV light source and the biological action spectrum. The DRS method was used to examine the UVA of the skin before and after the use of sunscreens and before and after UV exposure
