We aimed to investigate the psychological characteristics of their event-specific make-up behavior. Methods: The Psychological Characteristics of Makeup behavior by Event Study questionnaire (N=529; aged 50-80 years) included 30 items related to emotional experiences, 45 items related to personality factors, and 60 items related to makeup behavior, which were divided into three event categories. Principal component analysis was used for factor extraction and the Vermax method for factor rotation. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed, and this review was registered at PROSPERO (CRD420250651697). Results: Four factors with 12 items were examined for personality factors. Five factors with 18 items were examined for make-up behavior. Conscientiousness was the strongest correlation of personality factors and politeness was the strongest correlation of make-up behavior. Conclusions: The findings suggest that the new older generation has positive emotional experiences prior to participatory events, values social norms and harmonious relationships with others. Psychologically, we found that they have a strong psychological predisposition to actively participate in the events they attend and to seek out external beauty.

Introduction By the late 2070s, the number of people aged 65 and over worldwide is expected to reach 2.2 billion, surpassing the number of people under 18 [1]. In high-income countries, continuing increases in life expectancy are now mainly due to declining mortality among those who are older [2]. This has led to an ongoing debate in Japan about raising the retirement age to 75 or more [3,4]. Research into the growing elderly population and aging well has been ongoing for decades. “Aging well” includes successful aging, active aging, healthy aging, positive aging, productive aging, and competent aging [5,6]. High-income countries have seen the emergence of the Active Senior Generation, a group of 50–75-year-olds with a wealth of work experience and economic and spending power [7]. South Korea entered an aging society in 2000, when the population aged 65 and over exceeded 7%, and an aged society in 2015, when the population aged 65 and over exceeded 14%. It is expected to enter a super-aged society by 2026, when the population aged 65 and over will exceed 20 percent [8]. By the middle of the 21st century, it is expected to be like Japan, where 30% of the population is over 60 years old [9]. In 2021, as South Korea joins the ranks of high-income countries [10] and the elderly
