My doctor wants to do 6 vials Of Kybella at one sitting, is this realistic for a dramatic change? (Photo)

you will get minimal improvement with kybella and a lot of swelling. you can do treatments and the number of vials Is based on the size, but you will need a series of treatments to see any outcome.  it would be best to get neck liposuction + facetite.  See link attached.
With significant neck sagging you would need a neck/face lift with muscle tightening (platysmaplasty). at the same time lasers (fraxel,  co2 or erbium( or microneedling RF (fractora, intensif) can be . performed to improve the crepe skin or wrinkles.  You need a formal consultation, as the neck can be treated with a combination approach:
1. micro needling and lasers for texture
2. botox, disport or xeomin to help platysmal bands
3. intensif or fractora RF microneedling for crepe skin and lifting
4. fillers like belotero, restylane silk, juvederm volbella to improve lines and folds
5. neck/face lifting if sagging is prominent or early starting +/- platysmaplasty (muscle tightening)
6. J plasma/Renuvion, thermiRF, inmode facetite for internal tightening
7. ultherapy and thermage for external tightening
8. regular Venus legacy, exilis ultra, or inmode forma treatments with facials to maintain tightness
9. PDO novathreads or silhouette instalift cone threads for lifting and long-term collagen production
see an expert for a full evaluation and treatment plan based on your individual situation and goals.

Dear mzlovebird,
Kybella typically takes 3 to 5 treatments to work. This is why I've stopped carrying Kybella in my office.  I recommend neck liposuction more often then any injectable procedure for the neck now. It provides superior results gives me more control over the area than any injectable.  It also costs about the same as what you paid for your first kybella session. The liposuction can be done under local while awake in the office and recovery is about the same as kybella.
