Cell Biotech’s DUOLAC Selects Kang Ji-young as New Brand Model

DUOLAC, a leading probiotic brand in South Korea, has selected former announcer and broadcaster Kang Ji-young as its new brand model. The appointment is part of the brand’s strategy to strengthen its R&D-driven premium probiotic image and more effectively communicate DUOLAC’s core competitive advantage — gut survivability.

DUOLAC expects strong synergy with Kang Ji-young, citing her professionalism and trustworthy communication skills as qualities that align closely with the brand’s direction. In particular, the company believes her clear and reliable delivery will help effectively convey the importance of probiotics that survive and reach the intestines, moving beyond the market’s current consumer focus on guaranteed bacterial counts.

Rather than competing simply on the number of probiotics, DUOLAC focuses on actual delivery efficiency within the body. To achieve this, all products are formulated with the globally patented "Dual Coating" technology, designed to help probiotics survive even in harsh gastric acid and bile acid environments. Through this technology, Cell Biotech continues to differentiate itself in the premium probiotic market by securing both probiotic survivability and stability in the gut.

In addition, DUOLAC plans to expand consumer engagement through various online and offline marketing activities with Kang Ji-young, including TV commercials, digital content, and brand campaigns.

A representative from Cell Biotech stated, “Kang Ji-young is a figure who can create strong synergy with the premium brand values pursued by DUOLAC through her professionalism and credibility,” adding, “We will continue striving to communicate DUOLAC’s differentiated technology and the importance of gut survivability to consumers in a clearer and more accessible way.”

Meanwhile, Cell Biotech, the company behind DUOLAC, is a leading Korean biotech company that achieved the localization of probiotics by becoming the first in Korea to successfully mass-produce probiotics in 1995. DUOLAC, the premium probiotic brand based on Dual Coating technology, has maintained the No.1 position in probiotic exports for 12 consecutive years.
