Your smile is more powerful than you think

Smiles can change our mood, make someone’s day and even break down barriers - but sometimes we forget about the power of our smile. Whether you’re getting ready for a night out, or about to have the job interview of a lifetime – you should make your smile the best it can be.

If you don’t believe us, explore this page to find out how powerful a smile really is.



Download the Smile Detector app

iOS app Android App

The Smile Detector app from our film is now available for you to download. Use your phone’s camera to feel when someone is smiling and share the power of a smile.

The app has also been developed working closely with sight loss charity Royal National Institute of Blind People (RNIB) to make sure it is fully accessible to blind and partially sighted people.

How to get it

You can download it for free for iOS or Android devices in their app stores. Just search for “Listerine Smile Detector” or click the links above.

How it works

Just download the app and open it up. Choose the front or rear facing camera on your phone and point it at someone to be notified when they smile. The app will also play a sound when it detects a smile, but if a vibrate is enough you can mute it by clicking on the settings icon.
