In summer 2017, South Korean women filed a class-action lawsuit against sanitary product manufacturer Klean Nara after widespread allegations of negative health effects such as reduced menstrual flow, change in blood odor and viscosity, and skin rashes, after using Klean Nara’s Lilian pads. Both accurate and timely knowledge and safe materials were at the crux of the issue in this case.
For interview, our team recruited 10 Korean and US women ages 18- 40 who regularly purchase sanitary products. In the interviews, we specifically found that:
They lack of reliable information related to women health
They focus on seeing objective information and safety rating criteria
They desire to share menstrual experiences related to product use
They have time-sensitivity of information
Based on the interview findings, we had hour-long brainstorming session to freely exchange ideas and rated the ideas with the criteria of relevance to the problem and expected impact to the primary users.
The Rotten Cherries platform seeks to combine third- party independent laboratory evaluations with community engagement tools (such as forum-like elements) to foster a conversation surrounding sanitary products and menstrual health.
Ingredient Information and Safety Rating: An at-a-glance rating method using green, yellow or red icons next to each product, drawing from approaches used by existing consumer product safety databases
Forum: Users can submit their experiences and provide feedback on existing discussions by navigating to tabs for reviews and comments
Cycle Tracker: An integrated menstrual cycle tracker and detailed symptom tracker allows women to monitor their cycles for fertility or general health purposes
We iterated two round prototyping sessions with total 10 females and modified the application user interface and flow with the user feedback.
▪ Participants were concerned about security and identity. Updates to our prototype included requiring sign-in to ensure security. Anonymous commenting is available for user convenience after log-in. Approved users also had the option of creating a unique username to protect their real identity.
▪ Participants wanted to quickly know the credibility of the product information. As a result, we modified our rating icons slightly from a color-coded system to icons with text ‘safe,’ ‘fair,’ or ‘harm’. We also made sure to visibly reference the information that informed our rating decision, so users had easy access to the original documentation.
▪ Integrated a forum-style comment section on each product page where users could comment and start discussion threads. Each comment has a heart button to allow users to mark when a comment is particularly helpful to them. Users can follow the discussions of product pages of interest, viewable from ‘My Page.’
▪ Added an activity log on the user’s personal profile page recording their reviews and comments to help track issues of interest.
▪ Added symptom tag functionality on product pages to provide users with at-a-glance information regarding other user’s reported concerns with products.
