Skittles do you exfoliate just before just before going? If not do that and use and really good moisturizer between sessions, that should help.
Mystic Tan sells an exfoliater and moisturizer, but a brown sugar scrub will do better and is cheaper.
And I really like Supre Hempz moisturizer....you can get it on ebay for around $10 and will last you a long long time.
