1 year post op genioplasty, 6 months post op implant, face still looks off - options? (Photos)

A year ago I had a genioplasty where the doctor took me down 8 mm and reshaped the chin for a more square shape. I was disatisfied with the square shape so I got an implant. My appearance was improved as well as my confidence, but I am still left with sagging skin around my chin. As you can see in the before, I had quite a nice contour to my face that seems to be lost now. What can be done here? FaceTite? Also, I still think my chin looks very square. What are my options? Thanks!
