METHOD FOR APPLICATION OF A COSMETIC COMPOSITION CONTAINING AT LEAST ONE ACTIVE SUBSTANCE TO SKIN AND A MEANS FOR CARRYING OUT THIS METHOD FOR APPLICATION OF THE COSMETIC COMPOSITION

The invention relates to a method for application of a cosmetic composition in the form of a (hydro)gel or a cream containing at least one active substance, in which this cosmetic composition (3) is applied on the skin (1) at the site (2) of desired action, whereupon it is at least partially overlaid by a barrier layer (4), which contains polymeric nanofibers made of or containing as one of its components at least one biocompatible polymer and/or its copolymer and/or at least one biopolymer and/or its derivative, and/or prior to being applied on the skin (1), the cosmetic composition (3) is applied on the surface of such a barrier layer (4), which is subsequently put with its surface with applied cosmetic composition (3) on the skin (1), by which means the cosmetic composition (3) and the site (2) of desired action of its active substance/substances are closed against external influences, but remain accessible to atmospheric oxygen. The invention also relates to a means for the application of the cosmetic composition (3) containing at least one active substance, the means containing the cosmetic composition (3) applied on a barrier layer (4), which contains polymeric nanofibers made of or containing as one of its components at least one biocompatible polymer and/or its copolymer and/or at least one biopolymer and/or its derivative. L'invention concerne un procédé pour l'application d'une composition cosmétique sous la forme d'un (hydro)gel ou d'une crème contenant au moins une substance active, cette composition cosmétique (3) étant appliquée sur la peau (1) à l'emplacement (2) où l'effet est souhaité, mais au moins partiellement sur une couche barrière (4), qui contient des nanofibres polymères constituées de, ou contenant en tant que l'un de ses constituants au moins un polymère biocompatible et/ou son copolymère et/ou au moins un biopolymère et/ou son dérivé, ou contenant un de ceux-ci; et/ou avant application sur la peau (1), la composition cosmétique (3) est appliquée sur la surface de ladite couche barrière (4), laquelle est ensuite appliquée sur la peau (1) par sa surface ayant la composition cosmétique (3). De ce fait, la composition cosmétique (3) et l'emplacement (2) où l'effet de sa ou de ses substances actives est souhaité sont protégés contre des influences externes, mais restent accessibles à l'oxygène atmosphérique. L'invention concerne également un moyen qui permet d'appliquer la composition cosmétique (3) contenant au moins une substance a
