A HORIBA Jobin Yvon spectrofluorometer with double grating monochromators for both excitation and emission can be used for noninvasive in-vivo determination of sunscreen PFA via diffuse-reflectance spectroscopy. Because of the extremely low level of stray light that these monochromators allow, our spectrofluorometers can measure highly scattering samples, such as human skin, with excellent sensitivity and precision. Diffuse-reflectance DR) spectra of human skin both with sunscreen and without can be directly measured in vivo and differentiated within minutes. The ratio of spectra with and without sunscreen results in trans- mittance spectra of sunscreens, which allows calculation of PFAs. This non-invasive method provides an alternative diagnostic tool for quick and accurate determination of PFA of sunscreen products.
