Collagen, which occurs naturally in the body, consists of one-third of the protein. Its synthesis is important for forming the human body, such as skin, bones, and cartilage. Hydrolyzed collagen,  also known as collagen peptide,  can be acquired from pig`s skin or fish scales by degrading the collagen into smaller molecular weight with zymolysis or other methods. Recent studies revealed that the collagen peptide is effective for lengthening the diameter of collagen tissue and increasing the density in the human skin dermis. GNS`s Collagen Water is made with Hydrolyzed collagen sourced from fish scales and fish skin under 3,000 molecular weights to improve skin condition. Hydrolyzed collagen comprises a small molecular peptide with glycine, proline, and hydroxyproline. These small molecular peptides are easily absorbed and decomposed.
