Abstract

The present invention relates to a hyaluronic acid-based hydrogel which is a hyaluronic acid-peptide crosslinked body crosslinked using a peptide crosslinking agent. More specifically, the present invention relates to a hyaluronic acid-based hydrogel and a method for producing same, wherein a crosslinked body having novel physical properties is obtained using a relatively small amount of a crosslinking agent that forms peptide bonds, unlike conventional crosslinking agents, and the hyaluronic acid-based hydrogel has the advantages of: being safe and having few side effects; the physical properties of a filler being adjustable according to the amount of peptide crosslinking; and having a high elasticity ratio.
