The World's First Deodorant Device Powered by Bio-Plasma Technology
"I haven't used deodorant in 3 months. Here's why."
A New Era for Odor Care. The Deodorant That Never Existed Before
Conventional deodorants work by using aluminum salts and triclosan to block sweat glands and reduce perspiration. They're effective, but they come with the risk of skin irritation and other health concerns.
PlaDeo started with a different question.
"What if, instead of blocking odor, we eliminated its cause?"
Where Medicine Meets Technology
PlaDeo is the world's first bio-plasma deodorant device, designed to eliminate the bacteria at the root of body odor — without any chemicals or sweat-gland blockers. Reactive oxygen species (O3, OH-) safely sterilize odor-causing bacteria and break down odor molecules.
Developed jointly by the Plasma Medical Research Center at Hanyang University College of Medicine and CodeSteri Inc., the technology is the result of five years of research, two published papers, a registered patent, and a CES Innovation Award.

Ranked #1 Most Innovative Deodorant Formula by TrendHunter
Selected as the world's most innovative deodorant by TrendHunter, the world's largest trend analysis platform.
Clinically Grounded, Officially Patented
Korean Patent No. 10-2712188 (registered September 25, 2024) — a plasma-based electronic deodorant technology that eliminates the microbial root of odor without toxic ingredients.
Scientifically Validated in a Leading Peer-Reviewed Journal
Published in Scientific Reports (2024), a peer-reviewed journal from Nature Portfolio. Confirmed to eliminate odor-causing bacteria (including Staphylococcus hominis and Corynebacterium xerosis) and neutralize key odor molecules (including S3M and M2H3M).
Clinically Tested on Real Users Under IRB Approval
Approved by the Clinical Trial Center at Hanyang University Hospital (HYU-2024-293). Across 33 participants from 19 countries (60% female, 40% male), 94% reported noticeably reduced or eliminated odor.
Validated on Wadiz First
Funded on Wadiz -- chosen first by backers who recognized innovation and health.
"I could get through summer without worrying about sweat -- I noticed the biggest difference right after a shower."
"Underarm odor always came back by 3pm no matter what I used -- now it just doesn't. It's honestly surprising."
"Easy to use, and the effect seems to last well after use too."
Sold in 43 Countries, 700+ Units and Counting
Through its Indiegogo campaign, "PlaDeo: World's First Bio-Plasma Deodorant Device," PlaDeo has sold over 700 units across 43 countries -- earning the trust of consumers worldwide as a new personal care solution built to replace traditional deodorant.
"Something as basic as odor care shouldn't require applying chemicals to your skin every day. That belief is what started this project."

Frequently Asked Questions
PlaDeo's Proven Innovation
What exactly is PlaDeo and how does it work?
A patented bio-plasma technology generates reactive oxygen species like O3 and OH-, sterilizing odor-causing bacteria and breaking down odor molecules — with zero chemicals.
Is plasma technology safe to use on skin?
The silicone pad never directly touches your skin, and the plasma-generating component stays roughly 100mm away from it. Class II double insulation meets international safety standards.
Why does the non-contact design matter?
It reduces skin irritation, keeps usage hygienic (no cross-contamination), applies plasma safely, and eliminates any electrical risk.
Does it work for severe body odor (bromhidrosis)?
PlaDeo isn't a medical device, but it directly targets the bacteria that cause bromhidrosis.
Is PlaDeo legally protected?
Yes — Korean Patent No. 10-2712188, registered September 25, 2024.
Scientific & Clinical Validation
Is this product scientifically validated?
Clinical trials showed a 94% odor-reduction rate, published in Scientific Reports, part of the Nature portfolio.
Has it been tested on real users?
Yes — an IRB-approved clinical trial at Hanyang University (HYU-2024-293) in October 2024, with 33 participants from 19 countries.
Safe for Everyday Use
Is it safe to use every day?
Yes. It contains no aluminum salts, triclosan, or other chemicals, and has passed clinical and safety testing.
Can people with sensitive skin use it?
Its chemical-free, non-contact design minimizes the risk of skin irritation.
Does it produce ozone?
KTR testing measured 0ppm ozone, well under Korea's 0.2ppm safety limit.
Use & Care
How do I use it?
Simply hold it against your underarm after a shower or before heading out — that's it.
How long does one charge last?
Up to 150 minutes, or roughly 10-20 days depending on use.
Are refills or consumables required?
None. It's a fully self-contained device that only needs charging.
How do I charge it?
With the included USB-A (5V/2A adapter) to USB-C cable.
Where It's Made & What the Name Means
Where is PlaDeo made?
In South Korea, co-developed by the Plasma Medical Research Center at Hanyang University College of Medicine and CodeSteri Inc.
How is it different from the earlier name, "Pragrant"?
Pragrant was the research-stage prototype. PlaDeo is the finished consumer product — refined in design, safety-certified, and clinically validated. PlaDeo = Plasma + Deodorant.
Please Note
PlaDeo is designed for external underarm use only. Do not use on: inside the mouth or nose, ears or ear canals, eyes or the skin around them, or wounded or damaged skin. If you experience persistent or unusual body odor, please consult a medical professional.
