To provide a method objectively evaluating the apparent skin state of the face of a subject.
In the method of evaluating the skin state, the luminance of a measurement object part in the face of the subject is measured, its histogram is obtained, and the skin state of the face of the subject is evaluated on the basis of the shape of the histogram. The installation position of a light source is set at a position inclined by -90 to 90 degrees in the view of a horizontal plane to the median line of the subject and the position of inclination of -30 to 75 degrees to the horizontal plane passing through the face of the subject in the view of a vertical plane. The installation position of an imaging means is set at a position inclined by -90 to 90 degrees in the view of the horizontal plane to the median line of the subject and at the position of the inclination of 0 to 75 degrees to the horizontal plane passing through the face of the subject in the view of the vertical plane.
