Self tanning lotion

When using Jergens, people say to moisturize.

Sorry for sounding stupid, but does that mean like put a regular light lotion on before the jergens? Or just put on jergens?

I only put it on after a shower and I air dry until it's all soaked in and dry and then I'll get dressed. I wash my hands everytime and I apply it to the tops of my hands and feet with a foundation brush.
