What is the function of a compressor in air-brushing nails?

The function of a compressor in air-brushing nails is to provide a source of pressure to push the paint out of the gun. This is essential for the air-brushing technique, as the compressor generates a steady stream of air that atomizes the paint, allowing it to be sprayed evenly onto the nails. The correct pressure from the compressor ensures that the paint flows smoothly and adheres properly to the surface of the nails, resulting in a professional-looking finish. In contrast to other options, which either relate to heating, mixing, or drying, the compressor’s primary role is focused on delivering consistent air pressure, which is fundamental in achieving the desired application of nail art.
