摘要：The present invention relates to an anti-wrinkle composition containing adispersion of a polymer system comprising at least one polymer of natural origin, and tothe use of this polymer system as a tensioning agent in a cosmetic or dermatologicalcomposition. In particular, a soybean protein commercial product Profam 972.

< P>The polymer used must characteristically have a molecular weight of greaterthan 670,000 daltons and the polymer system obtained must be capable of forming asteam-permeable film, it must have a Young's modulus ranging from 10.sup.8 to

9×10.sup.9 N/m.sup.2 and it must produce, at a concentration of 7%, a greater than 1.5%retraction of isolated stratum corneum at 30° C. and at a relative humidity of 40%.< P>

The composition obtained is used in particular for the immediate treatment ofwrinkles and fine lines on the skin.
