The present invention relates to a process for preparing low molecular weight acetylated hyaluronic acid and its use. The low molecular weight acetylated hyaluronic acid according to the present invention is prepared by carrying out both the low molecular weight hyaluronic acid and the acetylation step of the polymer, and the low molecular weight acetylated hyaluronic acid prepared according to the method of the present invention is composed of hyaluronic acid Or low-molecular-weight hyaluronic acid, which is superior in collagen synthesis and anti-inflammatory effect. Further, according to the present invention, there is an advantage that hyaluronic acid is not denatured and mass production is easy. |
