Moisturize--get Body Drench excellent lotion, use it a few times a day especailly after tanning and showering.
Do not shower at least 2 hours after tanning, do not tan at least 1 hours after showering.
Start off slow in a tanning bed. If you have problems tanning start out 5 mins a session at first, after about for days of tanning go up to 10 mins per session, then 15 mins then 20 mins. It may take you 10 sessions but you will see some color. I was the same way, my grandsons are part mexican and tan without trying and I am right up with them now.
