CodeSteri Introduces PlaDeo: A Revolutionary Bio-Plasma Deodorant

On June 17, 2025, CodeSteri Inc., a fledgling startup affiliated with Hanyang University College of Medicine in Seoul, South Korea, unveiled PlaDeo, touted as the world's first bio-plasma powered deodorant device. This innovative product aims to effectively combat underarm odor and provide a solution for axillary bromhidrosis, a condition characterized by chronic underarm odor, without reliance on traditional chemical agents.

The device utilizes a unique plasma technology that generates reactive oxygen species (ROS) such as hydroxyl radicals and superoxide ions. These elements work to neutralize odor-causing bacteria and residues on the skin, offering a non-toxic and residue-free alternative to conventional deodorants which typically mask odors with synthetic fragrances or block sweat glands with aluminum salts.

Dr. Ji-Soo Park, a biomedical engineer at Hanyang University, emphasized the significance of this advancement, stating, "PlaDeo represents a paradigm shift in personal hygiene products, focusing on a scientifically grounded approach to odor control that prioritizes user safety."

PlaDeo's efficacy is backed by a peer-reviewed study published in *Scientific Reports* in 2024, which found that 94% of participants experienced substantial odor reduction after consistent use of the device. The clinical trial, conducted at Hanyang University Hospital, further validated these results, establishing PlaDeo not merely as a hygiene product but as a clinically relevant solution for individuals struggling with persistent body odor.

As consumers increasingly seek out chemical-free and scientifically supported alternatives in personal care, PlaDeo arrives at a pivotal moment. With growing concerns regarding the long-term health risks associated with ingredients found in traditional deodorants, such as triclosan and aluminum compounds, PlaDeo meets a burgeoning demand for effective and health-conscious innovations. Moreover, its compact and portable design renders it suitable for diverse environments, from gyms and offices to eldercare facilities and hospitals, where discretion and hygiene are paramount.

In a statement, Dr. Elena Kim, a dermatologist and clinical researcher, noted, "The introduction of PlaDeo aligns with current health trends, particularly among consumers who are more informed about the ingredients in their personal care products. It offers a safe and effective alternative that is likely to resonate with today's health-conscious market."

The CES Innovation Award winner in the Health & Wellness category in 2020, PlaDeo has received recognition for its disruptive potential in the personal care technology landscape. It is now available for pre-order on Indiegogo, where potential backers can support the campaign and learn more about the product.

As PlaDeo enters the deodorant market, it raises critical questions about the future of personal hygiene products. Will this bio-plasma technology pave the way for further innovations in personal care, and how will it influence consumer preferences in a market increasingly driven by health consciousness and scientific validation? Only time will tell, but the launch of PlaDeo certainly marks an exciting chapter in the evolution of deodorant technology.
