The object of the present invention is an injectable sterile aqueous formulation, ready-to-use, resorbable, used for aesthetic purposes as a particulate, cohesive, viscoelastic gel comprising i) crosslinked hyaluronic acid, or one of its salts, at a concentration of between 1% and 4% (mass/volume)； the crosslinking carried out providing the possibility of obtaining a gel based on crosslinked hyaluronic acid with a so-called cohesive structure, and ii) hydroxyapatite, at a concentration of between 5% and 60% (mass/volume), said hydroxyapatite being in the form of particles with an average size of less than or equal to 200 μm； said injectable sterile aqueous formulation having viscoelastic properties such that tan δ at the frequency of 1 Hz is less than or equal to 0.60.
