We present a novel method for studying the changing characteristics of sebum excretion of facial skin over a 3-hour period. Sebum production can be quantified by analysis of the pore patterns formed on a sebum-sensitive tape (Sebutape). We applied the CIE principles of reflectance colorimetry by measuring L*, a* and b* of Sebutapes every 15 min during 3 h of sebum collection. This combined technique yielded valuable new informations on the kinetics of sebum excretion, allowing the distinction between the follicular reservoir effect and the sebum flow.
我们提出了一种新颖的方法，用于研究面部皮肤在3小时内皮脂分泌的变化特征。皮脂分泌量可通过分析在皮脂敏感胶带（皮脂测试带）上形成的毛孔图案来量化。在3小时的皮脂收集过程中，我们每隔15分钟测量一次皮脂测试带的L*、a和b，应用了CIE反射比色法原理。这种联合技术产生了关于皮脂分泌动力学的有价值的新信息，能够区分毛囊储存效应和皮脂流动。
