ABSTRACT: Background: Evidence of effects by cosmetic therapy was obtained from participants who answered the questionnaires in psychological studies, and we need another method to validate. Purpose: The purpose of this study was to clarify effects of cosmetic therapy, investigating changes in facial expression of elders of nursing homes and analyzed by AI. Method: Elders with mild dementia in two nursing homes received cosmetic therapy once by a certified specialist. Elers put on makeup for themselves together following the specialist. The duration of cosmetic therapy was about one hour. They answered the questionnaires about well-being before and after it. Researchers took pictures of them. AI analyzed photos. Elders and staff described impression. Results: Elders’ face changed from calm, modest, suppressed, serious, tension and introverted to bright, open, soft, lively, familiar, and diplomatic. Categories of elders’ impression were “Feeling good,” “Waking up,” and “Feeling beautiful.” Categories of staff’s impression were “Promoting elder’s memory,” “Importance of doing by themselves,” “Elder’s positive behavior,” “Reflecting staff’s assumption,” and “Staff’s new finding.” Conclusion: Elders experience felt good or happy becoming bright and beautiful. Putting on makeup by themselves in cosmetic therapy makes elders active. Staff found the ability of the elderly. Cosmetic therapy was useful for well-being of elders in nursing homes.
