Thank you for your question! To recreate the shape of the face from the skull, we would use published Facial Soft Tissue Depths as a guide to estimate the thickness of the flesh on a skull. We follow anatomical and scientific methods to recreate the features of the face, for example, we could measure bony parts of the nose and estimate how far the nose sticks out from the skull! Through medical imaging techniques, we are are also able to conclude that the eyeballs sits slightly higher and to the side of the eye socket!
It is not possible to tell the wrinkle pattern or facial blemishes from the skull. To make the final face looks realistic, this is where you have to be artistic, creating a plausible face guided by scientific methods.
I hope this answers your question!
