VISCOELASTIC GEL FOR DERMATOLOGICAL USE

摘要

The invention relates to a polysaccharide gel of natural origin for dermatological use that comprises an aqueous solution of the polysaccharide of 0.1 to 5% by weight/volume, for example hyaluronic acid, and a viscous and strongly hydrophilic biocompatible alcohol at 0.5-5% by weight/volume, for example glycerol, and optionally the adjuvants that are commonly used in dermatology. The gel is prepared by mixing the polysaccharide solution and the strongly hydrophilic viscous alcohol before sterilizing the entire mixture by, for example, moist heat.

主权项

1. A polysaccharide gel of natural origin that is used for injection in dermatology, characterized in that it comprises an aqueous polysaccharide solution at 0.1-5% by weight/volume, and a viscous and strongly hydrophilic biocompatible alcohol at 0.5-5% by weight/volume, obtained by preparation of an aqueous solution of the polysaccharide and the alcohol, then sterilization of this solution, and optionally the adjuvants that are commonly used in dermatology, whereby the sterilization after mixing the components has the effect of appreciably increasing the viscosity of the resulting gel.
