Thoughts? Sagging glands, neck laxity, no contour 6 months post-op (Photo)

Procedure: High SMAS Facelift with Buccal Fat Removal and Submentoplasty 57-yr old female. From the Op Rpt: Incision on chin skin. Skin flaps elevated off plat muscle laterally. Fat removed by direct excision in neck and minimal subplat fat removed. Next plat edges up to level of hyoid with interrupted 3-0 PDS sutures. My PS has me going in for skin tightening treatments, but they are not working. Would appreciate input and ideas.
