Tiara,
I went for a trial to try it out if I like it. Basically those who have never tried indoor tanning before can only tan for max 9 mins. Subsequently,you can increase the time as you attend more sessions. They come in 5-20 sessions up to individual. I have yet to go for the 2nd tan as my chest area is currently healing and peeling too. It also depend on your skin type, i belongs to those that burn easily and turn red. Therefore lotions is a must after the tan to prevent your skin from dehydrating.They will provide you their special tanning lotion to bring out the colour
Usually they recommend tanning sessions once to twice a week depending on your skin type. My BS coordinator mentioned that twice is enough to even out the colour and the rest is to maintain it as she is a regular goer.
