Complex combining an organic silicon derivative with hyaluronic and acid calibrated fragments, for preventive and repairing action of cutaneous damages

摘要

The invention concerns a complex based on an organic silicon derivative. The invention is characterized in that said derivative is combined, by weak bonds, with one or several hyaluronic acid calibrated fragments of molecular weight comprised between 150 and 750 kDa, said derivative being of general formula (I): RxSi(OH)4-x, (I) wherein: R is a (C1-C4)alkyl, and x=1 or 2. The invention also concerns the use of such a complex in the prevention or the repair of cutaneous damages.
