Can you get a mini neck lift/neck lift after Kybella gone wrong? (Photos)

A consultation is important. You seem to have both aging (platysma band/sagging/skin looseness) and some lumpy irregularities. It appears (hedging without a consultation) that FaceTite to tighten the skin and smooth irregularities and a minimally invasive Ellevate/Trampoline platysmaplasty procedure (probably can be done without incisions) would likely tackle your problems.

There are many non invasive treatments to help with loose neck skin. Here are the options available.
1. Neck liposuction
2. Neck liposuction combined with Thermitight
3. Neck liposuction combined with necklift and lower facelift
4. Necklift and lower facelift
In your case the best option will be #4, Necklift and lower facelift including some liposuction and platysmaplasty. It will give you the best neck profile, tightness and longevity.
