I will definitely try the epsom salt trick.
I also shave my legs with hair conditoner, and I love it! And I save money from buying shaving cream.
One more trick: If you're out at a public restroom and your face is a little oily, use the toilet seat covers to blot out your face. The waxy paper is amazing, it will zap that oil without disturbing your face makeup. I read this in a magazine several years back and have been doing so since then. In fact, the other day I was in a bathroom doing this and the girl at the sink next to me exclaimed, "I do that too! It totally works!"
