Colgate lets a million unique smiles replace its logo — 'A Million Logos'
Against Asia-Pacific 'smile shame', Colgate turned its logo smile into each user's own via an AI generator — 899M+ reach and LIA Gold.
Colgate-Palmolive (Colgate)
What it had to solve
Oral-care advertising had spent decades showing only perfect teeth, and Colgate's own research found 94% of people in Asia-Pacific feel they can't smile freely, with 2 in 5 having experienced smile shame. Even Suzie Wadee, the brand's new ambassador with imperfect teeth, was shamed online — so Colgate set out to redefine what a beautiful smile means while lifting engagement and positive brand sentiment.
How it works
For decades oral-care advertising showed only flawless teeth, teaching audiences that a beautiful smile means a 'perfect' one. Colgate's research across Asia-Pacific found 94% of people felt they could not smile freely and 2 in 5 had experienced 'smile shame' — often triggered by social media comments. Even Suzie Wadee, the brand ambassador hired for her real, imperfect smile, was shamed online.
The fightback used Colgate's own iconography: the brand's logo is a smile, so on World Smile Day Colgate invited everyone to put their own smile there. A proprietary AI tool trained on more than 15,000 orthodontic photos traced a user's smile from a scan and rebuilt the Colgate logo around it, with illustrators hand-refining each result to keep the unmistakable mark while mirroring that person's teeth.
The campaign layered earned and owned media: PR released the smile-shame research, over 100 influencers received personalised toothpaste boxes printed with their own smiles as the logo, outdoor and social showed unique smiles, and Colgate employees shared their own stories on LinkedIn. The AI generator itself became a badge of confidence, producing shareable personalised smiles and hashtags.
Results reported in the award entry: more than 899 million reach (21x expectation), over 1,200 earned articles at 35x ROI with 100% positive sentiment, engagement up 14–29% in key markets, and a 10.4% uplift in Colgate's World Smile Day brand association on TikTok. The work won a Gold at LIA 2024 in Direct/Integrated and a Bronze in Direct at ADFEST 2025.
Why it lands
- The idea weaponized Colgate's own logo, the single most valuable brand asset, instead of buying a new message.
- Personalization made the movement real: each user's actual teeth became the creative, so participation was the campaign.
- Starting from a real research pain point — smile shame — gave the brand a purpose beyond product claims.
- The World Smile Day timing gave an unbranded cultural moment a brand owner for the first time.
What it did
The campaign reached over 899 million people (21x expectations), generated more than 1,200 articles at 35x ROI with 100% positive PR sentiment, and lifted engagement 14–29% in key markets, including a 220% increase in views on TikTok and Meta. The generator produced 2,400 personalized stickers and 2,300 hashtags, and Colgate's World Smile Day brand association rose 10.4% on TikTok. The work won a Gold at LIA 2024 in Direct/Integrated and a Bronze at ADFEST 2025.
What you can take
The most valuable visual asset can carry the argument: when people are ashamed of their smiles, letting them put their own smile inside your logo turns brand identity into proof of belonging.
Since then
Colgate's 'A Million Logos' grew from a World Smile Day push into a sustained Asia-Pacific platform, generating over 899 million impressions and hundreds of earned articles, according to the award entry. The personalised-logo generator kept working as a social tool after launch, and the case swept 2024–2025 industry awards, including LIA Gold and ADFEST Bronze. For Colgate it became a template for purpose-led marketing: lead with research, make the consumer the creative, and let the logo — not a new film — deliver the point.
