Hi guys. Lately I've been thinking about the characters appearance, and I've still thinking how to make Palpatine has the deformed face that he has in ROTJ.

From my thoughts, there are three options:

Make the dark side wear the body and if the user is so immersed in the dark side can even make changes in the body like deformations, etc.
Like the original prequels, that he leaves to be deformed or after an attack, he survives, but his face is deformed.
That in his past, he was a general, and his face deformations were some old war wounds.

What are your thoughts? What are your own ideas? Please let me know. Thanks.
