High Pollen, High Impact

Agency: Hearts & Science
Client: Opella - Allevia

In a category dominated by habit and price-driven switching, Allevia changed the game. Harnessing real-time pollen data and hyper-targeted creative, we intercepted hayfever sufferers at their most vulnerable moment: when symptoms struck. Our agile, data-fuelled strategy made Allevia the only logical choice. The result? Unmatched growth, record-breaking engagement, and a category-defining shift that left competitors scrambling. As the only hayfever brand to grow in 2024, Allevia didn’t just defend its #1 position—it made itself the only brand that truly mattered.
