I was working on something so I couldn't be more specific, but I checked what I used for one of my older female characters for which I used the photo of a young woman in Headshot.
I used a number of morphs that seem to come from the Ultimate Morphs pack:

This includes updated morphs from the older Essential Morphs pack as well as new ones. There are also useful morphs that come with Headshot.
For the skin I used things like wrinkles, pores, freckles, etc. that can be found in SkinGen. I have the additional SkinGen content that is available for purchase; I'm not quite sure how far you'll get with the base content.
Below is a composite screen capture of the various settings that I used:

I haven't done much with the new wrinkle system but that would give further options.
