Study of optical spectroscopy instruments for human skin sebum measurement

There are many techniques and instruments that are currently available to give better results for measuring the quality of human skin. In this study, two non-invasive spectroscopy instruments namely NIR Ocean Optic Spectrometer and ASD FieldSpec 3 Spectroradiometer were used to find the correlation between the clinical instruments (DermaLab Sebum Module). From the spectra of the reflectance that were generated at certain wavelength, the quantity of the sebum could be detected. The results of the three separated analyses showed different values and the best result was when the analysis was separated into five face regions.
