Marionette lines — the vertical grooves running from the corners of your mouth downward toward the chin — are named for the hinged jaw of marionette puppets, because they divide the lower face in a way that can make expressions look exaggerated or downward-turned. They form from a combination of volume loss in the midface and cheeks, downward pull of the DAO (depressor anguli oris) muscle at the mouth corners, and deepening skin folds. At Elevate Aesthetics in Glendale, we treat marionette lines with a tailored combination of Botox to the DAO muscle and hyaluronic acid filler to restore volume — delivering a lifted, natural correction without surgery.
The DAO muscle pulls the corners of the mouth downward. By injecting a small dose of Botox into the DAO bilaterally, the injector reduces the downward tension, allowing the opposing elevator muscles to lift the mouth corners slightly. This restores a neutral or subtly upturned mouth position, eliminating the default "frown" appearance caused by DAO dominance.
