Abstract:
1. A polysaccharide gel of natural origin that is used for injection in dermatology, comprising an aqueous solution containing 1.5-5% by weight/volume of hyaluronic acid of high MW 2.0 to 3.0 MDa, and glycerol at 0.5-5% by weight/volume, obtained by preparation of an aqueous solution of hyaluronic acid and the glycerol, then moist heat sterilization of this solution, and optionally adjuvants selected from the group consisting of vitamins, mineral acids, mineral salts, and nucleic acids, whereby the sterilization after mixing the components has the effect of appreciably increasing the viscosity of the resulting gel, compared to the gel without glycerol.
