ABSTRACT:
The present invention relates to a process for the production of cross-linked hyaluronic acid (HA) derivatives, in particular multiple, e.g. double cross-linked hyaluronic acid derivatives. The invention also provides novel cross-linked HA derivatives, products containing them and their uses in medical and pharmaceutical and cosmetic applications.
