Airbrush tattoos are by far the most realistic looking tattoos. You can touch them immediately, because they dry instantly. No mess! Henna tattoos are easily smeared and are normally a brown color while the airbrushed tattoos can vary in color. The FDA has banned henna for use on the skin, as many people have had serious skin reactions. The "crack, wet and peel" tattoos are messy and can rub off almost as quickly as they are put on. Airbrush Tattoos are the overall best choice.
