What lotion should I use for an arid environment?

I am going to be working in a very arid environment. It won’t necessarily be hot, but maybe on occasion I might break a sweat. Naturally my skin tends to be dry and I apply lotion after my shower every day. I’m worried that my simple lotion is not going to cut it in this environment. As it is right now my skin gets itchy in the dry spots and I scratch till it bleeds.

I think that I’d need something that is not just a cream I use to help keep my skin healthy, but it has to be something that actually protects it throughout the day. Something that is almost like a seal on the skin.

What lotion can any of you recommend that would help keep my skin protected?
