I want to say the name of the stuff is Lanacaine (?).
It's got benzocaine in it to dull the pain. I don't tan well, never did, but I keep a tube handy for when myself or the kids overdo it in the sun. My oldest didn't listen to his mom last year (sunscreen) and he blistered up really bad. (He's a redhead with really fair skin)
We also had a type of Aloe with either benzocaine or lidocaine in it that seemed to help. (Well,...if you squirt a bunch directly on the affected area the poor kid screamed like you'd just sliced his nipples off with a chainsaw...so go easy on it at first)
