PROBLEM TO BE SOLVED: To provide a simple but highly precise technique replacing beauty of skin to third party's eye to objective numerical values by using iridescence shown by horny layer cell itself as an evaluation index to provide information useful to discriminate skin status and to appropriately select articles of toilet. SOLUTION: Of discriminant techniques of skin, the present discriminant technique of skin is characterized by irradiating a horny layer cell with light at angle of 0 to 45 degrees, of the horny layer cell taken from skin, by observing interference light obtained via reflection from the horny layer cell, and by discriminating as more beautiful skin to higher brightness degree of iridescence of the interference light concerned.
