Airbrushing for makeup utilizes a freehand technique to apply makeup while manipulating aspects such as distance and PSI strength (air pressure) to produce certain effects and coverage. Airbrush makeup artists will either use a circular motion or forward-back motion with the air gun when applying foundation. Both dual-action and single-action airbrushes can be used for airbrushing makeup and require slightly different techniques.
A single-action airbrush is generally considered easier to use because depressing the trigger releases a fixed ratio of makeup to air. However, in order to achieve different levels of coverage and detail the nozzle has to be changed between applications.
Generally an airbrush makeup artist will work with a PSI range between 0-35 PSI. Many compressors designed for personal use in the home will not achieve airflow greater than 15 PSI. A low PSI is preferable when airbrushing makeup around the face and eyes while full body application (such as covering blemishes or tanning) is easier and faster with a higher PSI.
Pinkiou-Airbrush makeup is applied by layering several passes of makeup. This allows the artists to build upon previous layers to produce subtle changes. When applying foundation between 6-12 drops of makeup are used. The makeup is sprayed onto the face at a distance of 6-12 inches.
Stencils are commonly used to assist the application of difficult areas such as eye-liner. Stencils are also available for body-art and temporary tattoos.
