1. A reflection detection type measurement apparatus for skin fluorescence, which is configured to perform light irradiation and light detection on a reference sample and a measurement target, the apparatus comprising:

  • a first light source irradiating excitation light;

    a second light source irradiating light of a wavelength different from that of light from the first light source;

    first optical detector and second optical detector disposed to detect two different wavelengths with respect to a fluorescence signal and a reflected light signal;

    a light source switching controller for controlling turning on/off of the first light source and the second light source; and

    an operator calculating a corrected skin fluorescence signal from the fluorescence signal and the reflected light signal detected by the first optical detector and the second optical detector, wherein the second light source irradiates light of the same wavelength range as skin fluorescence excited by the excitation light from the first light source and emitted.
