Stinging jinx on Harry in DH

No: HPFGUIDX 187207

After rereading DH for the umpteenth time, something caught my attention.  When Harry says Voldemort's name and breaks the protective enchantments, Hermione uses a stinging jinx to make him unrecognizable.  The Snatchers take them to Malfoy Manor where it's still obvious that the jinx has been used.  I don't recall anything ever being said about someone undoing the jinx.  But once they are in the cellar, and even at Shell Cottage, no one says, "Hey, Harry, what happened to your face?"  I realize more important things were happening, but does the jinx just fade away or what?
