Current methods for analysis of sebum excretion have limitations, such as irreproducible results in repeatable
measurements due to the point measurement method, user-dependent artifact due to contact measurement or qualitative
evaluation of the image, and long measurement time. A UV-induced fluorescent digital imaging system was developed
to acquire facial images so that the distribution of sebum excretion on the face could be analyzed. The imaging system
consisted of a constant UV-A light source, digital color camera, and head-positioning device. We describe the system
characterization for acquisition of a fluorescent facial image and the image analysis method. The imaging modality
provided uniform light distribution on the facial mannequin model and presented a discernible color fluorescent image.
Valuable parameters of sebum excretion were obtained after image analysis. The imaging system, which provides a non-contact
method, was proven to be a useful tool to evaluate sebum excretion and to characterize the pattern of sebum
excretion. When compared to conventional "Wood's lamp" and "Sebutape" methods that provide similar parameters for
sebum excretion, the method described herein is simpler and more reliable to evaluate the dynamics of sebum excretion
in nearly real-time.
