I have lived in a very dry climate for last 6 years, it has become a necesity for me. I use a body wash in the shower several times a week--whatever brand SWMBO happens to buy. I have recently started using moisturizers on my face nightly too, seems to make a difference in my skin.
My liquid soap has moisturizers in it, but that is just dumb luck. I just like the brand. Sometimes the liquid soap leaves me feeling too smooth, like I have something on my skin. Girlfeiend says it is the moisturizers in the soap.
At the risk to repeat, I live in a very humid city, but still I must to moisturize my face and body at least 3 times per day.
