The film starts with a question; "Have you ever heard that you have bad breath?" Then show the hidden camera video. There are several people having a meeting in a room. When a man leaves the room to get a report, people start to gossip about his bad breath. They say bad things about him such as "He should drink only water," "He wouldn't get a girlfriend with that bad breath." When the man with bad breath returns, people pretend they haven't talked anything bad about him, and even give him a complement, saying, "Look at you, so handsome!" Then the copywrite comes up; 'Everyone knows, but nobody tells. The Only Solution: GARGLIN-Mouthwash.' The video ends with a message: 'Tag a @friend with bad breath!’

We released a film at Facebook that comes as a candid shot where people talk behind the person’s back about his bad breath. This film served as a wake-up call to wonder “Does my breath stink, too?”

And we told them to ‘tag a @friend with bad breath’, so that with a simple tag, people can drop hints to their friends with bad breath.

People who have suffered from friends with bad breath have become a human media by a simple action of tagging. They have delivered this advertising to the exact target audience in a direct and precise way.

Just in 3 weeks after the release date on September 1, 2015, this Facebook video was viewed 955,000 times.

In other words, 955,000 people are now suspicious of their breath.

Garglin sales increased by 17% merely in 3 months.

(Quarter sales before vs. after Sep 1, 2015)

It’s an astonishing result in the stagnant market for mouthwash of Korea.

Beyond being a simple viral video, this campaign improved people’s behavior by urging them to check their own breath.

If you’re having trouble telling someone their breath stinks, just show them this ad.
