This is an overview of my body material. It has three groups: Tanner - Darkens the albedo texture. Skin Pores - add detail normals (such as skin pores) to the normal map. Skin Shader - contains a principled shader with specific settings. A group can be included in many materials, but it is global. If you tab into a group and edit what is inside, every material that utilize the group is effected. This become useful when making renders of several characters, as it is inefficient to alter a setting in several body/face materials, compared to edit the setting once inside a group.

I find a little increase in gamma can help skin from being too pale. A multiply node with black or dark brown can also be helpful to dull down the skin if it appears too bright in a render.
