L'Oréal Paris · Brand Ambassador · announced at the Cannes Film Festival, May 2025
Becky Armstrong named a L'Oréal Paris Brand Ambassador
In May 2025, Thai actress Becky Armstrong was announced as a Brand Ambassador for L'Oréal Paris — the world's largest beauty brand — on the opening night of the 78th Cannes Film Festival, where L'Oréal Paris has been the official makeup partner since 1997. By the end of that week she was the brand's single most valuable face at Cannes.
How L'Oréal Paris introduced her

"Our ambassador from Thailand" · L'Oréal Paris
L'Oréal Paris presented Becky as its ambassador from Thailand at the brand's Cannes dinner on 14 May 2025, a day after she walked the festival's opening red carpet in its colors, under the brand's "Lights on Women" and "Worth It" banners. The brand's own TikTok post introducing her drew more than 200,000 likes — its most engaged Cannes post that year.
Paraphrased from L'Oréal Paris's Cannes 2025 posts · L'Oréal Paris on TikTokThe honor
L'Oréal Paris is the biggest beauty brand in the world and its ambassador roster is the most visible in the industry — a small international family that has included Eva Longoria, Kendall Jenner, Viola Davis, Jane Fonda and Andie MacDowell. Cannes is where the brand shows that family off: L'Oréal Paris has been the festival's official makeup partner since 1997, and the red carpet on opening night is, in practice, the brand's biggest campaign of the year. Being introduced there is the announcement.
Becky walked that carpet on 13 May 2025 in a white strapless gown as the brand's newest ambassador, two months after being named a Chanel House Ambassador in Paris — the fastest two-title run of any Thai actress. The next evening L'Oréal Paris hosted her at its Cannes dinner and posted the introduction that made it official. The week's trending record is on Global Highlights, alongside the L'Oréal trending party her fanbase ran around it.

The numbers
L'Oréal Paris measures its ambassadors the way every beauty brand now does — in earned media. Becky's first week in the role is the clearest case on this site:
- $11.1MEarned Media Value generated at Cannes 2025 — 44.1% of L'Oréal Paris's total EMV for the festival, making her the brand's top influencer of the event in her first week as ambassador
- #1Beauty influencer by Media Impact Value at Cannes 2025 — $12 million MIV and a 40.8% engagement rate; a Launchmetrics Top Placement for L'Oréal Paris
- #2Top creator engagement in the Asia-Pacific region for the festival (Wearisma)
- $1.1BTotal MIV generated across fashion, beauty and luxury at Cannes 2025 — the pool Becky was the beauty leader of
For a U.S. reader used to seeing those figures attached to American names: this is a Thai actress, in her first week with the brand, out-earning the rest of L'Oréal Paris's Cannes lineup combined. The full data set is on Global Highlights.
What followed
The appointment was not a one-off Cannes booking. In the year since:
Le Défilé, Paris
On 29 September 2025 Becky walked L'Oréal Paris's runway show, "Liberté, Égalité, Sororité", at the Hôtel de Ville during Paris Fashion Week — the same runway as Kendall Jenner, Eva Longoria, Cara Delevingne and Andie MacDowell, and her first Paris runway walk.
Thailand campaigns
L'Oréal Paris Thailand built its 2025–26 launches around her, including the Laque Résistance event in Bangkok. Her fashion career page has the full campaign list.
Global ambassador
In 2026 the role widened to Global Brand Ambassador — the title Tatler cited when it named her a Gen.T Leader of Tomorrow, and — with Chanel and the BoF 500, celebrated at the BoF 500 Gala in Paris the same week as Le Défilé — one of the credentials Tod's referenced when it signed her in August 2026.

When did Becky Armstrong become a L'Oréal Paris ambassador?
She was announced as a L'Oréal Paris Brand Ambassador at the 78th Cannes Film Festival in May 2025, walking the opening red carpet on 13 May and being introduced at the brand's Cannes dinner on 14 May. In 2026 the title became Global Brand Ambassador.
What is EMV, and why does 44.1% matter?
Earned Media Value estimates what the organic coverage around a person or event would have cost as paid advertising. Becky generating 44.1% of L'Oréal Paris's Cannes EMV means nearly half the brand's measurable attention that week came through her — more than any other ambassador the brand had on the Croisette.
