Blending in tanlines with spray tan.

Question: I'm looking to get rid of an awkward t-shirt tan before prom, will the spray tan only make my tanner spots tanner or will the spray tan be able to make me all the same color and hide the tan lines?

Answer: If you have a booth spray tan you will still finish with tan lines, because booth spray tan covers everything evenly, so everything will get darker, even the places that do not need to have any more color.
It will just blend in better, but not perfectly.
You could give yourself another coat in lighter places with a self tanner, but it is much easier to go to a salon where you get spray tanned by hand.

The technician will simply fill in the white places first, and then give you another coat over the whole body and all your tan will come out even.
