This invention relates to a sterile injectable aqueous formulation that is ready to use and resorbable, which is used for cosmetic purposes as a cohesive particulate viscoelastic gel containing i) cross-linked hyaluronic acid or one of its salts at a concentration between 1% and 4% (mass/volume)； with the cross-linking that is performed making it possible to obtain a gel having a base of cross-linked hyaluronic acid having a so-called cohesive structure, and ii) hydroxyapatite, at a concentration between 5% and 60% (mass/volume), said hydroxyapatite being in the form of particles having an average size less than or equal to 200 μm； with the said sterile injectable aqueous formulation having viscoelastic properties such that Tanδ at a frequency of 1 Hz is less than or equal to 0.60.本發明係關於一種用於美容目的之呈內聚性微粒黏彈性凝膠形式的即用型且可再吸收之無菌可注射水性調配物，其含有i)濃度為1%至4%(質量/體積)之交聯玻尿酸或其鹽中之一者；其中進行該交聯從而使得有可能獲得具有所謂之內聚性結構之具有交聯玻尿酸基質的凝膠，及ii)濃度為5%至60%(質量/體積)之羥磷灰石，該羥磷灰石呈平均尺寸小於或等於200μm的粒子形式；該無菌可注射水性調配物具有黏彈特性從而使得在1Hz之頻率下的Tanδ小於或等於0.60。
