PlaDeo—a sleek, handheld device powered by cold atmospheric plasma—is engineered to neutralize odor-causing bacteria under your arms, offering a scientific, deodorant-free approach to staying fresh using ionized gas and reactive oxygen species (ROS).
Impact:
Eliminates Odor at the Source: PlaDeo uses ROS like hydroxyl radicals and superoxide ions to destroy bacteria (e.g. Staphylococcus hominis, Corynebacterium xerosis) that produce smelly VOCs, and breaks down existing odor molecules—all without blocking pores or using chemicals . Clinically Supported Results: A trial with 33 everyday deodorant users across 19 countries showed that 94% of participants experienced a significant reduction—or complete elimination—of underarm odor after using the device 1–2 times daily. Lab tests confirmed that a 3-minute session killed over 90% of targeted bacteria . Safe, Skin-Friendly Design: The device maintains a 1?cm gap to protect skin from ROS exposure. Its battery supports approximately 2.5 hours of usage per charge, ideal for daily freshening . Chemical-Free Hygiene Trend: As consumers shy away from potentially harmful deodorant ingredients like aluminum salts or triclosan, PlaDeo offers a non-toxic, residue-free alternative tailored to sensitive users, medical facilities, gyms, or travel settings . Award-Winning & Readily Available: Building on the CES Innovation Award-winning “Pragant,” this evolved PlaDeo is now on Indiegogo for US?$149 (retail estimated at US?$249), signaling commercial readiness .
Why It Matters:
PlaDeo represents a shift from fragrance and sweat suppression to microbial management—enabling odor-free comfort without chemicals or skin clogging. That’s a game-changer for personal care: it bridges wellness, sustainability, and medical-grade efficacy in a compact, daily-use device.
If successful, PlaDeo could reshape deodorant products—promoting science-first, chemical-free hygiene as the next generation standard.
