Face masks for use in pressurized drug delivery applications such as aerosol , drug delivery systems and a method of reducing aerosol deposition in the region of the eyes are presented. The face masks according to the various embodiments disclosed herein contain features that reduce the inertia of the aerosolized drug in perinasal areas. This results in a reduction in the amount of aerosolized drug that is deposited in the region of the eyes by inertial impaction, while at the same time, the features are constructed to maintain the flow of the aerosolized drug into the face mask so that the aerosolized drug is effectively delivered to the respiratory system of the patient.
