L’Oréal Paris Transforms Plaza del Callao into a Giant Hyaluronic Acid Molecule with an Immersive Experience
On February 4th and 5th, Madrid’s iconic Plaza del Callao became the epicenter of innovation and beauty thanks to a spectacular initiative by L’Oréal Paris. To celebrate the launch of its new haircare line, Elvive Hidra Hialurónico, the brand carried out an activation that combined creativity, technology, and public participation, turning the plaza into a giant hyaluronic acid molecule.

The event, designed by the agency Pixel and Pixel and managed in media by Zenith, aimed to immerse visitors in the world of hyaluronic acid, the key ingredient in L’Oréal Paris’ new product range. To achieve this, an impressive geodesic dome was installed in the heart of the plaza, with a structure designed to represent the hydrating and plumping properties of hyaluronic acid. Inside the dome, attendees could experience firsthand the benefits of the Elvive Hidra Hialurónico line while being filmed by a 360º glam cam, a camera that captures dynamic images from all angles, providing a unique and immersive perspective.
The experience didn’t end there. The videos captured by the 360º glam cam were projected in real-time on the massive outdoor screens of the Callao Cinemas, allowing participants to see themselves on a grand scale and share their excitement with all passersby in the bustling plaza. This interaction not only created an emotional connection between the brand and the public but also amplified the campaign’s visibility, drawing the attention of thousands of people in the area.

The choice of Plaza del Callao as the venue for this activation was no coincidence. Known as one of Madrid’s busiest locations, the plaza offers constant foot traffic and a prime setting for large-scale events. Additionally, the Callao City Lights screens provided an unparalleled platform for high-definition content projection, ensuring that every detail of the experience was appreciated by viewers.
The campaign featured the participation of numerous influencers and beauty and fashion personalities, who eagerly joined the initiative and shared their experiences on social media. This strategic collaboration further expanded the campaign’s reach, generating significant impact on digital platforms and sparking conversation around the new product line.
The success of the activation was reflected in the impressive figures recorded during the two-day event. More than 1.5 million digital out-of-home (DOOH) advertising impressions were registered, reaching an audience of approximately 570,000 unique users. These numbers demonstrate the effectiveness of combining live experiences with digital strategies to maximize a campaign’s reach and impact.
