Plant-Based Period Pads Launch in US After Korean Success

Millions of people who menstruate may soon have access to a period pad that ditches plastic entirely for plants.

Inertia, a femtech company founded by scientists from Korea's top tech university, just launched Prism Pads in the United States. The product replaces the synthetic plastics found in most menstrual pads with materials derived from organic cotton, cellulose, and sugarcane.

The breakthrough centers on LABOCELL, a plant-based absorbent core that does the heavy lifting without superabsorbent polymers. These plastic-based SAPs appear in nearly every disposable pad on the market, even ones marketed as organic that only use natural cotton on the surface layer.

Prism Pads take a different approach. The entire structure uses plant materials: organic cotton certified by international standards on top, a bio-based absorbent core in the middle, and a sugarcane-derived backsheet on the bottom. No chlorine bleaching. No artificial fragrances or dyes. No plastic polymers touching skin.

The pads earned a USDA certification showing 82% biobased content. They also received a five-star rating from Dermatest for skin compatibility, addressing concerns many people have about irritation from conventional period products.

The Ripple Effect

Back in South Korea, Prism Pads became the number one feminine care product at Olive Young, the country's biggest health and beauty chain. The company has moved more than 10 million units since launching, showing strong demand for period products that prioritize both effectiveness and sustainability.

The US launch arrives as more consumers scrutinize what goes into products that contact their bodies for days each month. Traditional pads can contain dozens of synthetic chemicals and plastics, raising questions about long-term health impacts and environmental waste.

By proving that plant-based alternatives can work just as well as synthetic materials, Inertia is opening doors for the entire feminine care industry. When one company demonstrates commercial success with cleaner ingredients, competitors often follow, creating positive change across the whole market.

The shift toward transparent, sustainable period care gives people real choices about what they use during menstruation while reducing plastic waste that takes centuries to break down.
