摘要:
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 0.1% 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), the hydroxyapatite being in the form of particles with an average size of less than or equal to 200 μm; the 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.

摘要:
The present invention generally relates to hyaluronic acid-based compositions for aesthetic use, and more specifically to a dermal filler composition comprising hyaluronic acid crosslinked with citric acid or a salt thereof. Furthermore, the present invention relates to a method for preparing said dermal filler composition and its use for aesthetic purposes, in particular for skin rejuvenation and correction of fine lines.
摘要:
The object of the present invention is a method for obtaining an injectable hydrogel based on hyaluronic acid containing lidocaine hydrochloride and an alkaline agent, sterilized with heat, having hyaluronic acid concentration and flow properties, equivalent to those of the corresponding hydrogel based on hyaluronic acid not containing any lidocaine hydrochloride. The present invention also relates to various uses of the aforementioned hydrogel.
