Jannik Sinner arrives at Roland Garros as the world No. 1 and one of the defining stories of the 2026 season, fresh off a historic Italian Open title in Rome. The Italian defeated Casper Ruud 6-4, 6-4 to become the first Italian man to win the tournament since Adriano Panatta in 1976, while also completing the full set of ATP Masters 1000 titles.
As Sinner’s profile continues to rise, so does the visibility around everything connected to him — from his on-court dominance to the brands aligning with his ascent. In sports, athletes compete amidst a sea of logos. Sponsorship is everywhere. Logos cover caps, shirts, rackets, and shoes—every surface becomes brand real estate, each one fighting for the audience’s attention.
But La Roche-Posay found one thing that has never been sponsored. One thing that’s been right beside athletes all along: their shadow.

That’s the premise behind Shadow Sponsor, the bold new sports sponsorship by La Roche-Posay, created in partnership with the world’s #1 tennis champion Jannik Sinner. The Italian-born Sinner, known for his redheaded complexion, has partnered with La Roche-Posay for the past three years to promote the importance of sun protection.
In a category-first move, La Roche-Posay is officially “sponsoring” Jannik Sinner’s shadow—positioning it as the world’s #1 Shadow Ambassador—to transform a simple visual cue into a powerful behavioral trigger for sun protection.
Why shadows? Because shadows are built-in UV indicators: the shorter and sharper your shadow, the stronger the UV. By anchoring sun safety to a universally visible signal, La Roche-Posay introduces a new mental shortcut: Shadow Protection Factor—a simple mnemonic designed to drive real-world behavior change at scale and turn awareness into instinct.

A first in sports, the creative idea is simple but impactful: If you see your shadow, protect yourself. The unique sponsorship launched with a hero film introducing audiences to an unexpected voice. “I’m the sign the sun’s out. I’m the sign UV is strong. I’m the sign you need protection,” says Sinner’s shadow in the campaign, reframing SPF as an intuitive, always-on habit.
“Sponsors spend millions to be seen. La Roche-Posay spent time and energy to protect from what can’t be seen, UV radiation,” said Alexandra Reni Catherine, Global General Manager at La Roche-Posay.
Global skin cancer cases are projected to rise significantly, with melanoma incidence expected to increase by nearly 50% by 2040.* Athletes, especially outdoor athletes, are at a greater risk as they receive significantly higher UV exposure and routinely exceed safe limits.

La Roche-Posay, the life-changing skincare brand recommended by 100,000 dermatologists worldwide, continues its 50-year fight against skin cancer by using creativity to bridge the gap between awareness and action, embedding sun protection into everyday life in a way that feels immediate, personal, and impossible to ignore.
The campaign also showcases La Roche-Posay’s Anthelios range, including UV Pro-Sport and UVMune formulas, engineered for high-intensity activity and extreme conditions—reinforcing the brand’s authority in dermatological sun protection.
