My submental area has been over suctioned and left with slight platysma show, grooves and slightly loose skin. Everything I have read indicates fat transfer is ineffective in the anterior neck for this sort of defect. I do not want a lift/platysma repair. No more scars/tissue damage. Has anyone had success with Renuva for an over suctioned submental defect? Thank you for your help and any suggestions for repairing this sort of problem (besides a surgical repair).
