Start working those arms out!
I guess, for me, my skin goes through good periods and bad periods. OK, not good, but not god awful. When I lost quickly they would look bad. Then after a stall they would be a bit better.
And then, working them out makes a world of difference. I think its kind of like the hanger the skin hangs on...still I wont be hailing a taxi in a sleeveless shirt, but I can wear sleeveless shirts without feeling too self conscious.
