it's kind of like on bars - maybe ur skin will get harder and stronger after some practice and then won't peel off so soon from the turns. chalk is a good idea. Dominique Moceanu used to wear those beam slippers, so do some of the international gymnasts, not much in the U.S., but you could try them out, they're like around $15. also, another option is to take out those pirouetting turns on the beam when you get to optionals and put in more jumping dance skills!
