H.A. Supreme is a series of serum products from the Hada Labo family that promotes a mix and match approach. The line features three product SKUs - Vita, Cera, and Cica - each with specific functions. By combining Cera with Vita during the day and Cica during the night, consumers can achieve optimal results for their day and night skincare routines.

To encourage consumers to build a day and night usage routine, we have collaborated with Jer Lau @ Mirror to promote the Day and Night Duo. The campaign draws a parallel between polyphony and serum application, highlighting the amplified efficacy of combining different elements or nutrients from mix and match product usage. Jer's well-known singing skills and beautiful voice are utilized to efficiently introduce the product concept.

To further promote the Day and Night Duo, Hada Labo has extended the idea to social media, using feed and story features to encourage fans to try the mix and match routine for themselves. Through this campaign, Hada Labo successfully raises awareness among consumers and educates them about the benefits of a comprehensive skincare routine that combines different products to achieve optimal results.
