A new hydrogel made of crosslinked glycosaminoglycans, particularly crosslinked hyaluronic acid, chondroitin or chondroitin sulfate, having reversible linkages using boronic acid or boroxole derivatives leading to new benefits. Glycosaminoglycans that are crosslinked via an alkoxyboronate ester anion formed between a diol portion of a diol-functional moiety grafted to a first glycosaminoglycan and a boronate hemiester grafted to a second glycosaminoglycan.

A new hydrogel made of double crosslinked glycosaminoglycans, particularly crosslinked hyaluronic acid, chondroitin or chondroitin sulfate, having reversible linkages using boronic acid or boroxole derivatives leading to new benefits. Double crosslinked glycosaminoglycans, one linkage via two ether 5 bonds with a hydroxyl group of each of two glycosaminoglycans and another linkage via an alkoxyboronate ester anion formed between a boronate hemiester grafted to one of the glycosaminoglycans and a diol function of to the other glycosaminoglycan. The diol function may be a backbone diol function or a diol portion of a diol functional moiety grafted the other 10 glycosaminoglycan.
