摘要：
The present invention refers to the injectable hyaluronic acid composition which is crosslinked viscoelastic hyaluronic acid gel comprising DNA fractions. More particularly, it refers to the injectable hyaluronic acid composition comprising a hyaluronic acid composition crosslinked in the basic conditions with the degree of crosslinking between 0.1 and 200%, which is mixed with the DNA fractions of 0.1 to 50 wt %. The DNA fractions are selected, for example, from polynucleotide (PN) and polydeoxyribonucleotide (PDRN). The composition used for cosmetic purposes or therapeutic purposes, have improved viscoelastic rheological properties and enzyme resistance.
