I wasn't displeased with the coverage or appearance of it. They were running a special at the time so two appointments were $25. Apparently it has an enzyme that reacts with the skin that causes the tan look, but there is iodine in the solution so they can see it and hopefully get an even coat. That's how it was explained to me. There are tanning beds at the gym where I'm a trainer so, I guess that's gonna be what I do from now on.
