Abstract

A method for caring for and/or making up wrinkles includes the application to a wrinkled skin using an applicator of a mixture formed at the time of use from a composition in the form of a powder includes at least one antiwrinkle active principle and from a supplementary composition includes a solvent medium for the said antiwrinkle active principle.

         2 . Cosmetic method for caring for and/or making up wrinkled skin comprising at least the following stages consisting in:
 a) having available at least
 an application means exhibiting an application surface; 
 a composition in the form of a powder comprising at least one antiwrinkle active principle in the solid state, the said composition being substantially devoid of solvent for the said active principle, and 
 a solvent medium comprising at least one solvent for the said active principle with the said composition and the said solvent medium coexisting separately, 
   b) impregnating and/or coating the application surface of the said application means with the said solvent medium, and   c) bringing the said application surface treated according to b) into contact with the said composition for the purposes of withdrawing the said composition, and   d) bringing the said application surface treated according to c) into contact with the said wrinkled skin,   it being possible for stages b) and c) to be carried out consecutively in the chronological order b) then c), or simultaneously.
