Abstract: The state of blood vessels deep in the face is easily identified. An evaluation method includes acquiring information relating to an evaluation target person, the information including an actual age of the evaluation target person and an answer to a questionnaire about skin of a face of the evaluation target person; and predicting a state of a blood vessel in a deep part of the face of the evaluation target person from the information relating to the evaluation target person.

Abstract: The reason why under-eye sagging has changed is determined. A method according to an embodiment of the present invention includes acquiring information on a three-dimensional shape of an under-eye area of a subject when the subject is in a vertical position before a change in under-eye sagging of the subject and information on a three-dimensional shape of the under-eye area of the subject when the subject is in the vertical position after the change in the under-eye sagging; and determining a reason for the change in the under-eye sagging, based on a volume difference between the three-dimensional shape of the under-eye area of the subject when the subject is in the vertical position before the change in the under-eye sagging and the three-dimensional shape of the under-eye area of the subject when the subject is in the vertical position after the change in the under-eye sagging.

Abstract: Factors that cause a sagging appearance are found, and sagging is evaluated based on the found factors. A method according to one embodiment of the present disclosure includes a step of acquiring a gravity-induced prominence amount and a gravity-induced hollowness amount that are acquired from a change between a three-dimensional shape of a three-dimensional face image of a subject in a horizontal position and a three-dimensional shape of a three-dimensional face image of the subject in a vertical position; a step of calculating an intrafacial movement induced sag amount and an anteroposterior buccal sag amount from the gravity-induced prominence amount and the gravity-induced hollowness amount; and a step of evaluating a type of sagging and a degree thereof based on the intrafacial movement induced sag amount and the anteroposterior buccal sag amount as indices.
