Abstract
Change in appearance is a significant stress factor experienced by postpartum women. This study focused on postpartum cosmetic behavior. Objective 1 was to understand the condition of postpartum cosmetic behavior. Objective 2 focused on understanding the relationship between cosmetic behavior and mental health. The participants were 206 multiparous women in their 20s to 40s who had given birth in the past year. Result 1 showed that the time spent on cosmetic behavior was significantly reduced after childbirth. Moreover, the content of cosmetic behavior was simplified after childbirth. Results 2 showed that those who were satisfied with the cosmetic behavior had a higher self-affirmation, which reduced feeling down.
