Is there an expert on here on Express Tanning solutions, I use Fake Bake and not even they at Head Office can explain how it works! My questions are if it's water reactive why does it make a difference how long you keep it on for? My clients that I'm trying to convert are always asking me 'but how does it actually work'? hhhmmm I'm not really sure!! Not the best way to market a product! Any help would be much appreciated tia
