Another name for a jowl or jaw line lift is the Nefertiti Lift, after the ancient Egyptian queen. During this liquid lift of the lower face, a muscle-freezing toxin is injected into the muscles that pull down your jaw line. The injected toxins stop activity in the nerves that causes these muscles to move. This lifts the jowl and jaw line, causing to have a more contoured appearance. Filler can also be used at certain points along the jaw line, to help lift and define.
