Abstract:
Provided is a microneedle patch which is easily to be applied on a skin surface. One or more holes are provided inside a protective sheet of the microneedle patch, and one or more cutting lines running from an outer edge of the protective sheet toward the holes are also provided. The cutting lines may be symmetrically arranged on both sides of the hole. Providing an incision on the outer edge of the cutting lines of the protective release sheet facilitates cutting along the cutting lines. In the use of the microneedle patch, both sides of the cutting line of the protective release sheet are held and torn so as to bring out a microneedle array adhesive sheet and apply it on a skin. Then the microneedle array surface is slightly compressed, thereby the microneedle is inserted into the stratum corneum.
