not sure on the details pumpgirl, but i would say there are definitely chemicals in spray tans that you might not want to be having contact with. i'd look around for one that is the safest if i were you.. there is bound to be someone around who does a low chemical fake tan....? also i think a rub on one would be better than a spray to save you inhaling fumes and them getting in that way, but its all absorbed through your skin into your blood stream. good luck! you know, pale can be quite attractive as well :-)
