what tanning lotion are u using when u tan and what
moisturizer are u using at home.
what level bed are u laying in for 8 mins (20 min, 15 min, 10 min)??
even though your time is not that high, it may be too much too fast and could be over exposure. I would suggest taking a couple of days off and then going back to every other day. However, I am still curious about your lotions and level of bed.
