The invention concerns the use of hydrogels as a means of applying active
substances in the therapy of skin ailments and/or in the cosmetic treatment of
sensitive areas of skin and nail. These gels are flat, stiffly flexible
structures shaped to fit the contours of particular parts of the human body
and containing therapeutic and/or cosmetic active substances. These gels can
be placed on the skin instead of the usual semi-solid or liquid preparations
and plasters, providing a simple, clean way of applying the active substances
and contributing significantly to the healing of skin ailments and/or to
maintenance of the natural functioning of the skin. The hydrogels are also
suitable for the release of active substances to plants.
L'invention concerne des hydrogels qui constituent une forme galénique appropriée à l'utilisation de principes actifs dans le traitement médical d'affections cutanées et/ou le traitement cosmétique de zones sensibles de la peau ou des ongles. Ces hydrogels en nappe constituent des structures rigides-élastiques adaptées aux contours des parties du corps humain et contiennent des principes actifs thérapeutiques et/ou cosmétiques. Ces hydrogels peuvent être appliqués sur la peau de manière simple et hygiénique, à la place des préparations classiques semi-liquides ou liquides ou d'emplâtres, et contribuent singulièrement à la guérison d'affections cutanées et/ou au maintien des fonctions naturelles de la peau. Ces hydrogels s'utilisent également pour délivrer des principes actifs à des végétaux.
