The 40-year-old Scottish star now lives in Los Angeles with his wife and kids. He said that he was once offered the injections - which help smooth out wrinkles by paralyzing the skin - but said no because he needs to be able to express his emotions through his face.
He told Harper's Bazaar, 'I was driving into an airport the other day, and I saw a woman with her entire face bandaged up. It looked awful. My wife doesn't use it and nor do I. Someone offered it to me because I've got a frown mark and I said, 'But I'm an actor, I need to use my face.''
