It was minimal compared to Nicholson's. Ledger had the scars but it didn't alter his appearance totally, and the clown makeup was just clown makeup, and it was often rubbing off in the film. The point being that Ledger's own performance was the biggest thing that made him the Joker, not just the wardrobe.
