◎ Conditions the oral environment* and prevents bad breath for a long time
A triple approach to the cause of bad breath.
By conditioning the oral environment*, it keeps your breath fresh for a long time.
*By removing dirt and creating a clean environment.
◎ All products are non-alcoholic, low-irritation, and don't sting*
All products are non-alcoholic, making this mouthwash easy to use even for those who are sensitive to irritation.
