Abstract: A profile of optical reflectance relative to a depth within a depth range from an epidermis to an upper layer of a dermis is created based on a coherence signal obtained by optical coherence tomography, an evaluation index is determined by calculating a difference between reflectance at a local minimum point and reflectance at a second local maximum point from the created profile, and skin conditions are evaluated based on the evaluation index.
