Seoul– As global communities move beyond mask mandates, South Korean biotech company LUCA AICELL has introduced LUCA V-Defense, a drug-free nasal spray designed to act as a physical shield against respiratory viruses and allergens. The plant-based spray is emerging as a popular preventive tool amid ongoing threats from illnesses like COVID-19, influenza, and Mycoplasma pneumonia.
Unlike conventional nasal sprays that rely on steroids or antihistamines, LUCA V-Defense uses a non-medicated formula to create a protective barrier on the nasal lining. The spray features lambda carrageenan—derived from red algae—and antimicrobial lipids, which coat the nasal mucosa to block pathogens from binding to cells. The ingredients also offer anti-inflammatory and anti-allergic benefits, helping to prevent conditions like allergic rhinitis.
In a recent third-party laboratory study, the spray demonstrated 99.7% antiviral efficacy against SARS-CoV-2 within one minute of application. LUCA’s proprietary lipid nanocoating technology is credited with enhancing this rapid protection.
Sales of LUCA V-Defense have more than tripled in the last quarter, driven by growing demand from families and frequent travelers. With no vaccine available for Mycoplasma pneumonia, a leading concern for children, many are turning to non-pharmaceutical alternatives for everyday protection.
LUCA V-Defense is classified as a medical device, not a drug, and has earned FDA listing in the U.S., CE certification in Europe, and MFDS approval in South Korea—affirming its safety for daily use across international markets.
The spray is positioned as a safer alternative to traditional nasal decongestants, which can lead to rebound congestion or mucosal damage with prolonged use. LUCA V-Defense is steroid-free and suitable for sensitive users, including children, pregnant women, and individuals with chronic allergies.
“As the world enters a post-mask era, LUCA V-Defense offers a new approach to personal respiratory protection,” said a LUCA AICELL spokesperson. “It’s not just about preventing illness today—it’s about building a sustainable wellness habit for the future.”
LUCA V-Defense is available for over-the-counter use and is intended for daily application in high-risk environments such as public transit, schools, workplaces, and airports. (Source: IANS)
