A COMPOSITION BASED ON PERHYDROSQUALENE AND COLLAGEN-POLYVINYLPYRROLIDONE FOR FILLING MINOR CUTANEOUS DEPRESSIONS

The instant invention relates to a composition based on collagen-polyvinylpyrrolidone and perhydrosqualene for filling, through intracutaneous route, minor skin depressions to improve its aspect without producing a negative immune reaction or rejection of extraneous body, to a process for preparing it and to its use for the prevention and treatment of minor skin depressions through a temporary mechanical effect to prevent thus the encapsulation of the substance, because depending, among various factors, on the time, some compositions can generate a reaction against the extraneous body deriving in an inflammation of the treated region and fibrosis. The composition of the instant invention is characterized because it is prepared at a controlled alkaline pH and forms a stable, foamless emulsion.
