Improvement needed - what treatments would you recommend? (Photo)

I would recommend likely secondary facelift/necklift with some type of skin resurfacing (chemical peel, erbium laser, etc). I would find a board certified plastic surgeon (American Board of Plastic Surgery) with extensive experience in facial surgery. You need to be evaluated in person especially given a history of previous surgery.

It's difficult to make a precise assessment from the photo, but I believe that resurfacing your face will significantly enhance the texture of your skin, including your neck. We typically advise our patients to undergo some form of laser resurfacing annually to maintain skin quality. Regarding your neck, there appears to be excess skin or muscle that may benefit from revisiting a face and neck lift. This would involve treating the deeper layers and repositioning any extra skin to achieve a more favorable outcome. Since you've already had a facelift, we can strategically hide any new scars within those existing areas.

For you, I would do an extended deep plane facelift and Ellacor around the mouth. Ellacor will reduce the lines and fine skin around your mouth and chin (and cheeks)(. And the facelift will tighten your neck and jowls. I expect you to look significantly younger and more refreshed and ready to hit the stage or screen.
