Fluorescent image analysis for evaluating the condition of facial sebaceous follicles

Background/purpose: Conventional methods, such as ‘Sebutape’ and ‘Sebumeter,’ can provide quantitative information on sebum excretion but cannot reflect the condition of sebaceous follicles that can be indirectly evaluated with fluorescent colors of sebum. The images of sebum excretion can be obtained with an ultraviolet‐A light that is generally called ‘Wood's Lamp.’ In this study, we describe fluorescent image analysis methods for the detection of sebum and the color segmentation of sebum to evaluate the condition of sebaceous follicles.
