The mouthwash category grapples with a substantial awareness-usage gap, necessitating robust efforts to integrate it into the oral care routine of the audience. This is as a significant portion of Malaysians are still uninformed about proper oral health routine. Compounding the situation is Listerine’s comparatively lower budget when pitted against the toothpaste category. As the market leader in the mouthwash category, Listerine faces the challenge to reshape public perception and understanding of oral health, leveraging festive periods marked by increased food intake. The strategic focus during cultural events like Chinese New Year (CNY) therefore becomes paramount, aligning with customs and beliefs of spring cleaning that symbolizes clearing the old and bad luck for the new. In essence, the goal is to bridge the awareness-usage gap by associating Listerine with cultural practices and creating a meaningful impact during festive seasons.
