Hi,

I do mobile spray tanning as an evening job and have checked with my supplier plus done other research. The solution is sugar based and only reacts with your top layer of (dead skin) cells, it doesn't enter your blood stream so there are no more dangers to having a spray tan than to using shampoo, body lotions, fake tan creams etc. If you don't wish to inhale it then I think a mask is definitely a good idea. If you get one that is a natural based solution there should be no reactions to your skin. But i would always have a trial anyway to see if you like the colour.
