ABSTRACT:
Light Lo is allowed to be applied on the skin S, the internal scattered light Li in the region from the surface of the skin S to the microcirculation system is detected preferably in at least three wavelength regions of 400 to nm, 500 to 600 nm, 600 to 800 nm, or 800 to 1500 nm, and the optical properties which are affected by blood circulation, such as skin color, spots, and discoloration are determined. With these optical properties, the surface state of the skin can be evaluated better.
