What type of device is typically used in airbrushing?

The correct answer is that an airbrush gun is typically used in airbrushing. An airbrush gun is a specialized tool designed to spray a fine mist of liquid, such as makeup or paint, onto a surface. It utilizes compressed air to create a smooth, even application that can achieve various effects, from light sheens to full coverage. This precision is crucial in esthetics, especially for makeup applications where a flawless finish is desired.

Other devices mentioned, such as brushes, sponges, and sprayers, serve different purposes in makeup application. While a sprayer might deliver substances over a wider area, it lacks the control and finesse of an airbrush gun. Brushes and sponges, though effective for different techniques, do not provide the airbrushing effect, which relies on the air propulsion of the airbrush gun to create a seamless blend without leaving brush strokes or lines.
