Loose neck skin after mini lift. Can this be fixed?

"A combination approach would give the most improvement. Nonsurgical options such as Kybella, PDO NovaThreads, and Ultherapy do well in combination for skin tightening, but the results are mild compared to surgical options.

I would recommend a VASER Hi-Definition Liposuction with ThermiRF, Renuvion (J Plasma) and InMode BodyTite to contour and tighten the chin and neck. A neck lift can be performed at the same time, if you're a good candidate. I suggest seeing a board-certified cosmetic dermatologist to develop a personalized treatment plan that works for you. Best, Dr. Emer.​"

Fixing the skin would basically be re-doing the mini lift under local and getting what you really expected in the first place. Yes you can get the skin tighter and maybe Morpheus8 RF can help also.

You have a very nice profile-however not sure what your preop looked like. If you truly had a minilift, the neck was not addressed--as this is a procedure mainly aimed at improving the jowls.It may tighten the neck slightly, but in order to work on the neck, patients require a lower face and neck lift (aka 'facelift') or a necklift.Your neck has to have some give so you can move your head up and down, so there is a limit to how tight a neck can be. You could discuss with your doctor some skin tightening treatments like Infini, but I would not think that a weight change of 5 pounds would make a difference. Certainly does not need a surgical revision, I would try an energy device.
