Based on the coefficients of determination it was concluded that in vivo spectrophotometric reflectance measurements of human skin were highly useful for determining the eumelanin content of skin and to classify the pheomelanin content of skin non-invasively. This may be used individually and in population-based studies.

This study demonstrates that for a duration exposure of 20 min, facial skin treated with O/W achieves a lower temperature than facial skin treated with petrolatum. The two emollients had in all other aspects the same effect on the response of facial skin to cold.
