Jeju Green Tea Fermented Skincare Line 'Green Tea Essence'

The Green Tea Essence line is a core product series developed by Hanlyeon Bio over five years of research and development. It primarily uses three-year-old organic green tea cultivated on Jeju Island, combining the traditional "Seven Steaming and Seven Rolling" method with modern microbial fermentation technology. Through the proprietary patented "Low-Temperature, Low-Speed Fermentation" technology (Patent No.: KR10-2022-0056789), active ingredients with a molecular weight as low as 600 Da are extracted, enabling rapid penetration into the dermal layer of the skin. This line consists of five products—toner, essence, cream, mask, and eye cream—forming a complete skincare regimen.
The star product, "Green Tea Fermented Repair Essence," features a dual-chamber tube design: Chamber A contains fermented green tea polyphenols, while Chamber B contains hyaluronic acid. When dispensed, the two components mix to activate dual benefits of antioxidant protection and deep hydration. According to clinical trials conducted by the Korean Dermatological Research Institute, after 28 consecutive days of use, skin moisture content increased by 35%, wrinkles reduced by 23%, and skin elasticity improved by 18%. The product has passed dermatological sensitivity testing and is free from alcohol, mineral oil, and artificial colorants, making it suitable for all skin types. The packaging design integrates traditional Korean hanji paper craftsmanship with modern minimalist aesthetics, earning the 2023 iF Design Award. Currently available through premium channels such as Lotte Department Store and Shinsegae Duty-Free in Korea, the product has also entered the Chinese market via cross-border e-commerce platforms, receiving strong consumer response.
