PROBLEM TO BE SOLVED: To provide a technique for quantifying a skin condition of a subject with a high degree of accuracy.SOLUTION: A method of evaluating a skin condition uses skin image data which is acquired by receiving reflection light obtained by reflecting linear or point-like light projected on a skin of a subject by a surface and the inside of the skin and corresponds to an evaluation target area of the skin. The method of evaluating a skin condition includes: acquiring pieces of the skin image data comprising a set of images of a skin area apart from a projection position of the light on the skin by a prescribed distance with respect to respectively different, prescribed distances; calculating distribution values of reflection light intensity in the evaluation target area of the skin with respect to the respective prescribed distances from plural pieces of the skin image data acquired with respect to the respective prescribed distances; and evaluating the skin condition of the evaluation target area in accordance with respective spatial distributions of the reflection light by the skin surface and the inside of the skin that are indicated by the distribution values of the reflection light intensity that are calculated with respect to the respective prescribed distances. |
