[Win a chance to meet ENHYPEN!?] Listerine® launches 'ENHYPEN 21-Day Challenge Campaign'

Kenvue's medicated mouthwash brand, Listerine®, is seeing strong results from its partnership with the global group ENHYPEN. Following the success of the first phase, the company is launching the second 'ENHYPEN 21-Day Challenge Campaign' from June 1, 2026, to July 31, 2026. This campaign encourages users to establish a daily oral care habit by using mouthwash for 21 consecutive days. During the period, customers who purchase eligible products can enter a drawing for 325 prizes, including the grand prize: an invitation to a Listerine & ENHYPEN collaboration signing event in South Korea.

[Background of the Campaign] Listerine® is a pioneer in the mouthwash market and the No. 1 selling medicated mouthwash brand in Japan. Incorporating mouthwash into daily brushing routines makes oral health care easy to maintain. By appointing ENHYPEN as ambassadors, Listerine® aims to encourage oral care habits across a wide range of age groups.

*No. 1 Sales: Intage SRI+ (Mouthwash market, Jan-Dec 2025, by value share).

Since March 2026, the 'TO DO LIST LISTERINE®' TV commercial featuring ENHYPEN has been airing, supported by in-store and digital campaigns. This second phase aims to solidify these habits through the 21-day challenge while offering exclusive experiences with the ambassadors.
