PURPOSE: An in vivo apparent optical density and diffusive characteristics diagnosis device is provided to allow for a simultaneous measurement of in vivo apparent optical density and diffusion. CONSTITUTION: A method for measuring an in vivo apparent optical density comprises a step of applying drugs or cosmetics to a predetermined area of a skin; a step of receiving, by using an optical fiber member, the light reflected from the skin tissue by applying the light of 200 to 1000nm in a vertical direction to the skin; a step of detecting the reflected light at a predetermined time interval and storing a spectrum; and a step of calculating kinetics by displaying, on a screen, the spectrum stored in the previous step and representing the change of intensity of reflected light in a graph.
