Early morning in Gangnam, Seoul, Dr. Jung Min-sang slips on his white coat and reviews his daily patient roster. Among the first 10 appointments, seven live with varying degrees of periodontal distress: persistent bleeding when brushing, dull pain when biting into firm food, and for those with long-neglected symptoms, localized necrotic gum tissue and frequent dental caries. After 23 years in clinical practice, the scene is familiar—but it never sits right with him.

Through years of consultations, Dr. Jung observed a widespread gap in everyday oral care. Most people treat mouthwash as little more than a breath-freshening quick fix. Conventional alcohol-based formulas deliver temporary antibacterial effects but irritate already fragile gum mucosa, gradually wearing down the periodontal barrier. Gentle, alcohol-free alternatives, meanwhile, often stop at surface-level comfort, doing little to address active gum bleeding, tissue necrosis, or the bacterial root of tooth decay. “Oral care shouldn’t force people to choose between effective and gentle,” he says. Driven by that conviction, he and his team at the Seoul University Oral Biology Laboratory embarked on a five-year journey to reimagine the daily mouthwash.

The result is this purple restorative mouthwash—the physical embodiment of Dr. Jung’s “repair first, protect always” philosophy.

Where most formulas settle for soothing symptoms, this one targets the foundation of periodontal health. Active restorative compounds penetrate deep into gum soft tissue to support the repair of necrotic and damaged periodontal cells, improve local microcirculation, and ease redness, swelling and bleeding at the source. Over time, it helps receding, vulnerable gums regain firmness and rebuild their natural defensive barrier.

Against tooth decay, the formula deploys a targeted antibacterial system. It seeks out and neutralizes caries-causing bacteria in the oral cavity, interrupting the decay cascade before it takes hold. By reducing plaque buildup in hard-to-reach gaps and fissures, and leaving a long-lasting protective film over enamel, it fills the blind spots of daily brushing and deprives “cavity bugs” of any place to thrive.

The signature pale purple hue is the team’s quiet aesthetic touch. Food-grade color-correcting pigments use complementary color theory to instantly neutralize yellow surface tones left by coffee, tea and daily habits—one 30-second rinse leaves teeth looking naturally brighter. Paired with a low-irritation mint base, it delivers long-lasting fresh breath, balancing clinical-grade care with everyday confidence.

Crafted entirely without alcohol or peroxide, the pH-balanced formula has been rigorously tested for sensitive mouths. There is no harsh burn, no stinging aftertaste—just clean, calm comfort. Dr. Jung insisted on 20 individually sealed single-use sachets, too. His vision was simple: professional periodontal care shouldn’t be confined to the dental chair. It belongs in briefcases, travel bags and desk drawers, ready to work its quiet magic in 30 seconds after meals, before meetings, or on the road.

“Truly great care fits seamlessly into daily life—you barely notice it’s there,” Dr. Jung often says. And in every pale purple sachet, that clinic-born craftsmanship is already guarding smiles, one rinse at a time.
