Kelijin is a mid-to-high-end brand under Juzi Biotechnology Company, which is positioned in the field of functional skin care. It has anti-wrinkle firming and whitening as its core effect and is suitable for all skin types. Kelijin owns the national patented ingredient human collagen. This ingredient was released at the end of 2000 by using genetic engineering technology and high-density fermentation through bacterial fermentation and yeast fermentation. , a scientific invention was born from this. This human collagen prepared with different cell systems overcomes the inherent problems and defects of traditional animal collagen and has extremely high safety and effectiveness.

In 2003, Xi'an Juzi Biogenetic Technology Co., Ltd. officially registered the Kelijin trademark, which represents that Kelijin has officially entered the public eye. Among them, Kelijin's core ingredient human collagen, the patented technology has now been in biomedical engineering, It is widely used in many fields such as medical devices, medical skin care products, preventive medicine, nutritional medicine, etc. As the core component of the Corlign brand, it is a scientific research result of 20 years of dedicated research by 100 doctoral and master's students, which can greatly improve skin care capabilities.
