Abstract
The present invention relates to an antiwrinkle composition that includes, in a physiologically acceptable medium: PA1 a dispersion of a film-forming polymeric system containing at least one polymer capable of forming a film permeable to water vapor, having a Young's modulus ranging from 10.sup.8 to 10.sup.10 N/m.sup.2 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.degree. C. and a relative humidity of 40%, and PA1 a dendritic polyester polymer having terminal hydroxyl functional groups.
