Abstract
Devices and methods for electrostatic application of cosmetics are described. In one embodiment, a system for electrostatic deposition of cosmetic material on a surface includes: a housing; a nozzle configured for breaking the cosmetic material into cosmetic particles and for directing the cosmetic particles out of the housing and toward the surface; and a reservoir configured for holding the cosmetic material. The reservoir is connected to the nozzle. The system also includes an airflow conduit configured to provide air to the nozzle; and a nozzle electrode configured proximately to the nozzle. The nozzle electrode is configured to charge the cosmetic particles.
