Abstract

Abstract The present invention relates to compositions for the treatment of the skin containing up to 25% by weight of at least one polymer having carboxyl or carboxylate groups and aldehyde groups of chiefly rectilinear or cross-linked C--C compounds, the ratio of carboxyl or carboxylate groups to aldehyde groups in said polymer being in excess of 0.5:1, and particularly between 1.1:1 and 16:1, preferably between 2:1 and 9:1, and the polymerization degree being at least 3, preferably 3 to 100; as well as the method of skin treatment.
