The Soothing Cup comprises a menstrual cup and an incubator. A seaweed-based hydrogel turns the cup into a bio-membrane that can interact with the vaginal environment while the incubator enables users to grow their own anti-inflammatory bacteria on their personal menstrual cups to reduce periods discomfort. The level of care required in this ritual creates an intimate connection between the menstruator and the cup, reducing the desire to purchase single-use hygiene products whilst challenging the societal stigma around periods.
