Airbrush is just a different way of applying foundation. The airbrush is 7% thinner then traditional foundation. It creates a fine mist of foundation on to the face resulting in a flawless, even, and long-lasting finish, as opposed to a traditional application with sponges and brushes. You can spray on layers which build up coverage on the skin and depending on how many layers you put on, you can obtain various degrees of coverage. It can really adhere to the skin and last longer into the evening. If you prefer your skin to have really full coverage it may be the choice for you. It does cover tattoos and birthmarks very well. Both are beautiful and traditional can be made just as long-lasting as airbrush if done properly.
