Modern menstrual cups are revolutionizing period care for millions of people around the world. Every year more and more people ditch a life of pad and tampon consumption and realize the benefits of using a cup. Comfortable, safe, money-saving, and eco-friendly, they give us the ultimate freedom in menstrual care. But they haven’t always been such an enticing option.

The first menstrual cups

Menstrual cups first arrived in 1937 when Leona Chalmers, an American actor, and dancer, filed her first commercial patent. The idea was inspired and was a radical change in thinking at the time. She wanted to change how we look at period care but was unfortunately ahead of her time. People weren’t ready yet for the next step in period care.

Over later decades, more cups entered the market as our attitudes towards feminine care and using cups started changing. But with only tough latex rubber to work with, not everyone found menstrual cups comfortable or easy to use. The shapes were improving but the material wasn’t flexible or long-lasting enough to catch on.

Benefits of silicone

Silicone is a marvelous synthetic polymer with most in common with the rubber family with some plastic properties. It behaves differently than either rubber or plastic and is much more hypoallergenic than latex rubber. Latex rubber has become a common allergen. The flexibility of silicone makes it popular for use in many kinds of products, including cookware. With a soft feel and flexible movement of medical-grade silicone, modern menstrual cups like CapdCup are a perfectly comfortable alternative to pads and tampons. The softness of silicone allows you to move, sleep, work, and even exercise while wearing your cup without feeling it inside. 

Because silicone behaves differently from most plastics, it doesn’t break down and shed microplastics into the world. And it doesn’t leach chemicals when in contact with our skin, making it much safer for vaginal use. In the past decade, we began learning just how damaging microplastics have become to our health and the environment. Because it doesn’t break down the same way as plastic, silicone menstrual cups have a very long lifespan. Each cup can last up to 10 years before needing replacement. Compared with any menstrual care products, including reusables, silicone cups come out on top by a long way.

Menstrual cups continue to evolve
