NOVEL PROLINE-DERIVATIVE BASED COSMETOLOGICAL AND/OR DERMATOLOGICAL COMPOSITIONS AND USES THEREOF

摘要

The present invention relates to the necessities of life, and more particularly to the field of cosmetology and dermatology. It relates more particularly to novel cosmetological and/or dermatological compositions which bring about a very significant increase in the deposition of collagen type (III) in the extracellular matrix, characterized in that they contain, as active ingredient, a combination of a 4-hydroxyproline fatty acid amido ester, of formula (I): in which R<SUB>1</SUB> and R'<SUB>1</SUB> are identical or different aliphatic chains containing from 10 to 24 carbon atoms that are in a straight line or branched, and of an extract of the epicarp of the Opuntia ficus-indica (Barbary fig) fruit in an inert, nontoxic excipient or carrier suitable for topical use. Use in the form of a fatty cream or gel for the increased production of collagen, without amplifying that of procollagen (III) or of enzymes of the metalloproteinase family.
