It is not good to tan more than once in the same day!!  Your skin needs 24 hours and some needs 48 hours in between sessions.  If you do, it won't tan any faster and you risk damaging your skin.  Moisturize, moisturize, and did I forget to say moisturize.  Body Drench is fantastic stuff, don't shower too close to sessions, 2 hours after tanning, 1 hour before tanning those times are minimum.  Use tanning lotion.  Moisturize a few times a day and always during tanning session with proper step lotion, use moistuizer after showering and after tanning sessions and just for the heck of it.  If you get to the point you are dark but not getting darker, go a couple sessions with a step one lotion then go back to a higher step lotion and the lotions with hemp and bronzers are great.
