Abstract: The present invention relates to a kit comprising: at least one microneedle sheet comprising a substrate layer and a plurality of microneedles on the substrate layer, the microneedles comprising at least one water-soluble or water-dispersible polymer; and at least one applicator comprising at least one application surface, wherein the substrate layer of the microneedle sheet is capable of being attached to the application surface of the applicator. The kit according to the present invention can allow a user to easily store an applicator for microneedles without breaking the microneedles.

Abstract: Systems, devices, and methods are described for providing a cosmetic device configured to deliver an active component into a skin and a method for manufacturing such a cosmetic device. In an embodiment, the cosmetic device includes an anisotropic magnetic element located in or on the head part of the body and configured to generate a magnetic field which induces diamagnetism in the active component. In an embodiment, the anisotropic magnetic element has a honeycomb magnetization pattern.
