I do an airbrush spray tan and I love it ! I feel much more comfortable that someone who is trained in equipment and the proper way to airbrush is tanning me. Mine generally lasts for about 1 week sometimes a little longer. What my airbrush person has told me that with any type of do it yourself tan (airbrush, lotions, towelettes, regular spray tans, etc.) the length that the tan will lasts depends on the length of time the product is left on the skin before the first shower (I usually get tanned around 3pm and shower the next morning), and it will also depend on your skins ability to tan. For example I tan very easily, and (knock on wood) have never had a problem with the way the tan faded, but my friend who is very pale, doesn't tan easily, her tan lasted for 4 days and faded weird. It is up to personal preference, but I love getting airbrushed, its fast and provides great color. Also, many hair salons or beauty salons will provide airbrushes who are certified to airbrush tan !
