Abstract
Secreted skin oil is a complex mixture of lipids, cholesterol, fatty acids, and a large number of other components. Its composition varies among individuals and with changes in physiology. In this paper, the feasibility of obtaining reproducible spectra of skin oils from individuals with a very simple, noninvasive technique is reported. Using pattern recognition algorithms, spectra could be classified on the basis of ethnicity and gender. Differences in spectra between individuals were larger than those between replicate samples taken from the same individual. While there are easier techniques for gender and ethnic identification, our purpose in this paper is to show that information of some value exists in skin-oil spectra. We believe that this approach could be used for such practical discrimination problems such as the determination of high and low cholesterol levels if confirmatory information for training such classifiers were available.
