Is a repeat facelift better before jowling becomes really bad or better to wait until really necessary? (photo)

Thank you for your question and pictures.  This is completely down to patients preference, when it starts to bother you and there is enough skin laxity present then another procedure can be performed.  If it doesn't bother you then WAIT, if it is making you feel self conscious .  All The Best 

If you are happy with the way you look, then there is no reason to rush into a facelift revision simply because your surgeon is retiring; I am sure you could find another wonderful facial plastic surgeon to help you when you are ready. That said, you do have significant sagging under your chin and on the neck and it looks like you may have some new jowling as well. While there is no reason to rush, there is no reason to wait, either. If you are bothered by the sagging skin, then I'd at least recommend a necklift with or without a mini lift.
Waiting until your jowls get really bad before lifting them is a bit like waiting until your car is filthy before washing it. Yes, the change will be most dramatic when the car is dirtier, but then you've been driving around in a vehicle for months or years that doesn't look its best. Based on your photo, you are a very attractive woman and there's no reason to delay a procedure that will once again turn back your clock by years. While you are trying to decide, I'd suggest consulting with a few new facial plastic surgeons who are not nearing retirement, so that you have a few options and don't feel rushed by someone else's timetable. I hope this helps.

Thanks for asking the question.  Based on your images you could benefit from a revision procedure to improve your lower face adn platysmal bands.  Your decision to proceed is a very personal one.  Good luck.
