Marionette lines improve most reliably when we address both volume loss and skin quality rather than the line itself. Depending on your anatomy, I may place hyaluronic acid fillers, such as Juvederm, Restylane, or RHA lines to restore support around the lower face and gently add volume to the area. Lasers then address the skin side of the concern. Resurfacing with a device such as Clear + Brilliant Touch or UltraClear improves texture and tone around the mouth and stimulates fibroblastic function to enhance production of collagen, elastic fibers, and hyaluronic acid over the following months. A combination of injectables and laser treatment almost always reads more naturally than treating the line in isolation, which is why I would want to see you in person to determine the right products, devices, and sequence for your anatomy.
