Health Promotion Board's Less Salt Your Way OOH Advertising Campaign Reaches Singapore Commuters
Singapore's Health Promotion Board (HPB) and creative agency TBWA\Singapore have developed Less Salt Your Way, a public-health campaign that encourages people to ask for less salt, sauce or gravy and to select lower-sodium options. Rather than frame the request as a difficult dietary instruction, the creative makes it feel like an ordinary expression of personal preference.
The campaign extends from film and digital communications into Out-of-Home Advertising and Singapore MRT Advertising. Its bright-red graphics and high-contrast yellow text are designed for quick recognition in the rush of station entrances and concourses.
Outram Park MRT Advertising Turns Platform Doors Into Public-Health OOH Media
At Outram Park MRT station, the provided photograph shows campaign panels beside train doors. One announces 10 million Healthpoints to be won, while another urges commuters to “Ask for or choose less salt your way.” QR codes on the artwork provide a bridge from a physical transit placement to further campaign information.
Unlike a generic road billboard, station advertising can speak to commuters during the everyday transitions between travel, shopping and eating. The use of Indoor OOH Advertising helps place a public-health message directly into that rhythm.
Circle Line Station Takeover Uses Floor Advertising and Transit Media at Scale
The second photograph captures a Singapore transit concourse with large yellow campaign lettering across the floor and matching wall graphics near the fare gates. The statement “10 Million Healthpoints To Be Won” becomes part of the route passengers walk through, illustrating how Floor Advertising can complement posters and other station-wide media.
With one creative language across multiple surfaces, the campaign demonstrates the value of Integrated OOH Advertising and Transit Media. A commuter encounters the same message as a visual environment rather than as one isolated ad.
The Mouth Library Brings Interactive OOH and QR Code Advertising to HarbourFront MRT
The creative idea behind the wider campaign is The Mouth Library, a collection of expressive characters with different ways to request less salt. The campaign film uses playful personalities, ranging from a rapper to a singer and a Korean-drama-inspired character, to show that there is no single correct way to ask.
For November 2026, HPB also brings an interactive experience to HarbourFront MRT station. Visitors can scan QR codes and try different mouths, connecting a mobile interaction to a physical environment. This is an example of Interactive OOH and Experiential OOH, although the two supplied photographs depict the separate, static transit advertising executions.
OOH Campaign Strategy: Why Contextual Messaging Works in Public Transportation
The execution is an example of Contextual OOH Advertising: it delivers a small, actionable behavior-change message in locations where diverse audiences cross paths. Bright colors, clear calls to action and placement across commuters' sightlines all help the message remain legible.
The campaign also uses a promotional hook. HPB has announced 10 million Healthpoints available through competitions and partner activities running from September 22 to November 30, 2026. This creates a participation layer that can complement the awareness generated by the physical media.
What Brands Can Learn From This Singapore Transit Advertising Campaign
- Make the message practical: ask for less salt, sauce or gravy is an action that can be understood immediately.
- Design for the environment: combine large typographic floor graphics with high-visibility platform advertising.
- Connect physical and mobile channels: QR-enabled experiences can extend an encounter with station media.
- Use one consistent visual system: repeated colors and campaign language strengthen recognition across locations.
- Keep formats accurate: static station wraps and floor graphics are OOH formats; their presence does not establish programmatic DOOH delivery.
Final Reflection: Local OOH and Public-Awareness Advertising Can Make Everyday Choices Visible
By integrating transit posters, floor graphics, digital storytelling and an interactive experience, Less Salt Your Way demonstrates how OOH Marketing can make a public-health message familiar and approachable. Its strongest creative move is to make a small request feel socially normal, using commuters' everyday environments to carry that invitation.
