the brand problem:
listerine has long been hailed the fresh breath giver and clean mouth maker. But in more recent years, new science data has reported that some listerine products and mouthwash in general have given consumers negative side effects. So how does Listerine position its brand and product benefits among millennial, information-seeking audiences today?

my challenge:
Repositioning the well-known old-school mouthwash brand among millennial audiences.
