Abstract

A modified hyaluronic acid derivative is described having the —CH2-OH group of the N-acetyl-D-glucosamine unit (GlcNAc) modified to an aldehyde group having the structure —CH2-O—CH2-CHO where the degree of modification is 1.0% to 15.0% for preparing a crosslinked hydrogel for use in aesthetic applications. The modified hyaluronic acid derivative is prepared by reacting a glycerol-modified hyaluronic acid with an oxidizing agent such as periodate.
