Okuchi Lemon, with its memorable catchphrase “See the dirt and say goodbye to bad breath,” is a mouthwash that solidifies and washes away dirt and residue left behind in the mouth, as well as protein, one of the causes of bad breath.
This innovative product uses chitosan and tea leaf extract to bind with the protein, one of the causes of bad breath, by rinsing for 20 seconds, making it visible as brown clumps.
