BLOSSOM / Menstrual Skin Sticker


Females in poverty lack knowledge of menstruation and suffer from period-shaming. According to professional hygienic advice, a sanitary pad should be changed after 3 or 4 hours of use. But females in poverty often fail to manage their period properly and tend to overuse a pad, which can cause serious vaginal infection. Females can wear BLOSSOM skin sticker when wearing a pad. The color changes of the print, happening in 4 hours, indicate the hours of use and serves as a reminder that tells the user to change the pad to a clean one. It’s low-cost, accessible, and also subtle for females in poverty to wear during the day.
