I purchased the Groupon for Three Level 1 Mystic spray tans for $37 and some change. I went last night and the sign said that level one would increase your tan 1-2 shades. That's all I wanted. The girl behind the desk was super nice and friendly! The machines have come a long way since I last used one and the automated directions were given very clearly. There is also a sign that states to wait 5-8 hours after for the color to develop before showering or getting wet.
Well it has been about 14 hours, I haven't showered and I am not even 1 level darker. I am going to have to go back today or tomorrow and hope that going again makes a difference.
