Abstract
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.
