Antiwrinkle composition comprising a combination of tightening polymers of synthetic and/or natural origin and of dendritic polyesters

A method for the preparation of a cosmetic or dermatological composition intended for reducing and/or removing the wrinkles and/or fine lines on the skin, comprising combining:

• a dispersion of a film-forming polymeric system comprising at least one polymer capable of forming a film permeable to water vapour, having a Young's modulus ranging from 108 to 9×1010 N/m2 and producing, after application at a concentration of 7% in water and then drying, a retraction of the isolated stratum corneum greater than 1% at a temperature of 30° C. and a relative humidity of 40%, and
• a dendritic polyester polymer having terminal hydroxyl functional groups, to prepare a cosmetic or dermatological composition intended for reducing and/or removing the wrinkles and/or fine lines on the skin.
