Abstract

An apparatus that includes at least one nebulizer that includes a mesh material having a plurality of pores, a vibrating actuator coupled to the nebulizer and configured to produce ultrasonic vibration when energized according to a set energy profile, and a reservoir receiver configured to receive a reservoir that holds a topical formulation, the reservoir being coupled to the nebulizer when received. When the nebulizer is placed in contact with the topical formulation, vibration of the mesh nebulizer by the vibrating actuator, according to the set energy profile, ejects droplets of the topical formulation from the plurality of pores, forming a spray.
