Before seeing the movie, I got the comic adaptation which featured a scene after the bacta tank with the medical droid taking a bandage off of Luke's face. I saw it in the theater and said "that's not what it looked like in the comic book!" Other people who saw the movie at the same theater commented on the scene as well referring to the bandage as a "sheet of ice."

The footage of the bandage removal is indeed included in one or two of the early trailers, before the massive task of cutting the film together began. It is possible that you saw the trailer in the theater some time before the film, then, well you know the rest.
