Absolutely. One of the most important things that you must do is to thoroughly exfoliate before spray tanning. The shallower the dead skin layer on the surface of your skin, the more time it will take for this layer to build up before it starts rubbing off. That means the better the exfoliation, the more even your tan will be throughout it's life and the longer it will last. The best exfoliation by far is with a mitten. Of course it is just as vital to moisturize every day after spray tanning to keep your skin from drying out and exfoliating prematurely.
