high pressure booths are a waste of money, I own a Hollywood Tans, if there is one near you try the HT54. Get a package of 6 along with a bottle of brazilian hemp lotion (it contains bronzer in it). I will give you a schedule on how you should tan and you will be nice and dark, not red.
Go tanning every three days and increase your minutes to the maxium of 10.
Session 1 - 7 minutes
Session 2 - 8 minutes
Session 3 - 8 miniutes
Session 4 - 9 minutes
Session 5 - 9 minutes
Session 6 - 10 minutes
Thats should give you a good base tan in a span of 18 days, its sounds like a long time but its the only way to do it without un-necessary burning, remember burning is bad for you!!
