A needleless microprotrusion system for infusion of a medicament into a patient includes a plurality of microprotrusions having a length sufficient to penetrate a stratum corneum of the patient. A chemodenervating agent is disposed for delivery by the microprotrusions and a substrate is provided for supporting the microprotrusions and conforming the microprotrusions to a patient's fossa axilaaris in order to enable uniform penetration of the microprotrusions into the corneum.
