Biore (ビオレ,Biore), also stylized as Bioré, is a skincare brand owned by the Japanese company, Kao (花王,Kao). Kao sold the first Biore product, "Biore Facial Foam" in 1980. They soon began selling makeup remover and cleansing wash in the following years, which were marketed at "office ladies" or "OLs". In 1999, they revamped their "Biore Facial Foam". Over the next decade, Kao continued developing different kinds of makeup remover and face wash. Biore is also sold in the United States.
Biore began a marketing campaign featuring Boys Over Flowers, particularly the F4 in early August 2016. They also posted advertisements in the Tokyo subway system. Biore's website also has a quiz, which tells the customer which product to use with F4's comments.
