I want a defined jaw & tight neck again! I'm 60, have large glands & a lax jaw. What's the most effective procedure?

Based on your photographs, an expertly performed revision lower face and neck will provide you with a good results. You have some upper eyelid laxity so an upper eyelid surgery would improve it. You're doing ok on your lower eyelids. But I would recommend fat grafting with PRP to your cheeks. All of these procedures can be performed with local anesthesia and twilight sedation without the need for general anesthesia. Please see the link below.

Thanks for your question.  I think you could benefit from a expertly-performed redo facelift with neck lift.  I would try to shift your scars to a tragal-edge position to hide better, and tighten the platysma muscle as well as the SMAS.  Simultaneously, some fat grafting to the cheek area and nasolabial crease area would help re-establish more youthful contours.I don't think you have prominent submaxillary glands - so I wouldn't recommend resecting those.Best,
