The present invention relates to an injectable hydrogel, including, in weight, in a physiologically acceptable carrier fluid: 0.01 to 5 % of glycerol and 0.1 to 5 % of cross-linked hyaluronic acid, or one of the salts thereof; characterized in that the hyaluronic acid or one of the salts thereof is cross-linked by the formation of covalent bonds using bifunctional or polyfunctional molecules, said injectable hydrogel being sterilized in moist heat and having viscoelastic properties such that Tanδ at a frequency of 1 Hz is less than or equal to 1.10. The present invention also relates to a method for producing said hydrogel, to a kit containing said hydrogel, as well as to the use thereof in dermatology. |
