You can get the same effect by applying your liquid foundation with a stippling brush. Dab your foundation in the normal spots - nose, cheeks, chin, forhead. Spread the foundation all over your face using many, many rapid circular movements with the brush. Afterward, do the same circular motions with a large powder brush and setting powder.
Alternatively you can use mousse foundation instead of liquid formula, which tends to give an airbrushed effect by itself.
I don't think it's practical to airbrush your makeup on a daily basis. That seems like something reserved for special occasions only.
