No, Lupin does not have any scars on his face.
While Remus Lupin, the werewolf character from the Harry Potter series, experiences significant physical transformations during his werewolf state, these changes are temporary. The werewolf form is characterized by heightened aggression, increased physical strength, and a change in appearance, but it does not leave permanent scars on his face.
Lupin's physical appearance is largely consistent throughout the books. The character is described as being tall, thin, and having a rather gaunt face. He is often seen with a tired expression and a somewhat melancholy demeanor, but there is no mention of any facial scars.
