What is a good way to add skin shade detailed with paint? like in the lines and folds of the face.
If we are talking about headsculpts for 1/6 figures I am the type of person who thinks that the shading should be achieved by the sculpt itself naturally under different light conditions, but some people apply washes of a darker skin tone. If painting miniatures or models, then washes are a must.
Here's a small tutorial of how to apply wash on a miniature:

It's the same principle if you are to apply on a sculpt.
He uses premade washes by citadel. You can thin the paint with water and then apply it just the same.
