A method of using a microneedle device and a microneedle device suitable for application to the skin. The microneedles are optionally made of one or more biocompatible polymers that provide a cosmetic advantage when dissolved in the skin. Optionally, the microneedles may also be used to deliver other active ingredients to the skin. The device is characterized in that it comprises a microneedle layer, an intermediate layer of a liquid soluble polymer and an external liquid pervious layer in fluid communication with the intermediate layer. In use, the device is applied to the skin such that the microneedles penetrate the surface of the skin. A liquid (e. G., Water) is applied to the outer layer to dissolve the intermediate layer to separate the microneedles in the skin from the device body. The rest of the device is then removed and discarded. |
