L'Oréal reclaimed its eroded slogan by giving it back to its author

For fifty years, L'Oréal Paris's 'Because I'm Worth It' was everywhere, but its feminist fire had softened into a tagline repeated without feeling. The campaign's goal was not to reinterpret the line but to reclaim its power by going back to the woman who wrote it, 23-year-old copywriter Ilon Specht, whose name and voice had never been known.

McCann Paris worked with Oscar-winning filmmaker Ben Proudfoot to capture Specht, facing a terminal illness, telling her own story in her New York apartment — unscripted, with no brand messaging and no product shots. The film premiered on International Women's Day 2025 and became the first branded content acquired by TED, streaming on TED, AMC+ and Prime Video.

The campaign treated the story as cultural restoration rather than advertising: OOH in over 20 countries, avant-premieres at Tribeca X and MoMA's Doc Fortnight, and interactive photo booths that let 12,000 participants step into the slogan's 'I.' Restoring the author's voice also restored the slogan's meaning.

Reclaim the slogan by returning authorship to its writer

Returning authorship to the line's creator gave the slogan back its original defiance.

A documentary had more cultural weight than a commercial could ever claim.

TED's acquisition certified the work as thought, not marketing.

The origin story was an untapped asset no competitor could copy.

When a brand asset loses meaning, don't modernize it — go back to the moment it meant something and return authorship to its source; the story itself becomes the campaign.

The film earned more than 2 billion impressions, a 9/10 IMDb score and a 97.9% like ratio, and drove a 70% increase in brand consideration for L'Oréal Paris. The work made the Cannes Lions 2025 Titanium shortlist and went on to win a Film Grand Prix, a Gold Entertainment Lion and other metals, plus a One Show Gold Pencil in 2026. It also made Ilon Specht known as the author of one of advertising's most famous lines.
