There used to be aging packages at DAZ 3D to do these things.
I think there are rudimentary age morphs that are part of the Morphs ++ Packages. I don't know if they still carry them.

Tempesta3D has a number of aged characters for both V4 and M4 in their store... https://www.renderosity.com/mod/bcs/?uid=558334 you'll have 4 pages of unique characters to examine!!
Good luck!
