Abstract:
A low-molecular-weight hyaluronic acid and/or its salt has an average molecular weight of 5000 to 20,000, and has a molecular weight distribution in which the proportion of components having a molecular weight of 10,000 or less is 40 wt % or more and the proportion of components having a molecular weight of 50,000 or more is 5 wt % or less.
