Do you find it necessary to use the other two steps, ie, the moisturizer/lotions? I am just using step 3, the mousse. It works okay, but I'm wondering if the other two steps have been found to get better results. If I had to take a guess, I would say probably, but I've not had luck with the multiple step sunless tanners, so I'm skeptical. Just wondering what your experiences are with it for those who use St. Tropez (or have suggestions of kinds that may even work better) Thanks!
