"Tanmaxxing" is one of the latest viral TikTok trends doing the rounds.
Burger King Belgium used the sharp marks left by sunburn to argue that some things are better left on the grill.
Created by Happiness Brussels, "Leave The Flame Grilling To Us" pairs aggressive tan photographs with the brand's signature line.

The campaign appears across social media, digital OOH, wildposting, and the tram network along the Belgian coast.
Burger King gets to comment on a risky social trend, and the joke works as both memorable advertising and a nudge toward healthier skin habits.
Burger King Makes Sunburn Part of the Brand
The creative centers on the stark white shapes left behind when clothing or accessories shield skin from the sun.
A cap leaves its outline, sunglasses create their own frame, and necklaces and shorts produce similarly recognizable patterns.
Each mark becomes evidence of Burger King's flame-grilled cooking.

The placement adds another layer. Social and digital formats meet audiences online.
Out-of-home ads do the harder job, since the Belgian coast tram puts the work into the environment, where sun exposure is part of the trip.
Most executions skip branded items, leaving the sunburn pattern and the headline to do the work.
When product imagery appears, it remains secondary to the visual gag.
The campaign also avoids stepping into health-advertising territory, and it does not pretend to act as a PSA.

Burger King connects a recognizable consequence of overexposure to a brand asset it has spent decades establishing.
The payoff for any brand is ownership, since a gag tied to long-running brand positioning stays yours even when competitors chase the same trend.
Gen Z Takes Its Skincare Advice From Influencers
"Tanmaxxing" arrives as sun-safety knowledge remains uneven, particularly among younger audiences.
The American Academy of Dermatology’s 2026 Practice Safe Sun Survey found that 64% of Gen Z respondents had encountered sunscreen misinformation online.
The same survey also showed that 36% of Gen Z names Instagram or TikTok influencers as their primary source of skincare advice.
More than 160 million U.S. adults got a suntan in 2025, including nearly 60 million who did so intentionally.
Tanning pulls in far more people than a niche social trend suggests.
The survey covers U.S. adults, and Burger King is running the work in Belgium, though the TikTok behavior it answers moves across both markets.
The data gives marketers a clearer framework for approaching health-related trends without positioning brands as medical authorities.
- Track the creator conversation. Marketers should watch for emerging trends and misinformation where responsible brand messaging can add value.
- Anchor the joke in brand truth. Companies should tie trends to existing brand assets to stay credible without overstepping expertise.
- Put the media where the behavior happens. Brands should consider where and when behaviors occur to make media placements more relevant and useful.
Any brand entering a health conversation has to keep the claim inside what it actually sells, the same test that good influencer marketing passes.
Our Take: Can Placement Make the Joke Matter More?
The Belgian coast tram may be the smartest part of the campaign.
Burger King took a behavior that lives on TikTok and put its answer where people are actually sitting in the sun.

We think that placement makes the joke matter more, since a sunburn gag reads differently on a tram platform in August than on a phone screen in February.
The risk is that the same visual reads as a trophy, as tanmaxxing videos treat a deep burn as the goal.
The tagline sits dead center in most of the executions, so everybody catches the warning.
Media choice becomes part of the argument when a brand comments on a risky trend, which is why the tram beats the timeline here.
