Am I a good candidate for Kybella or would you recommend chin augmentation?

You can treat submental fat with Kybella injections,chin liposuction or CoolSculpting. Kybella often requires multiple treatment sessions and the results appear in the months following treatment as the body naturally eliminates the treated fat cells. Liposuction is a one-and-done procedure that can be performed using local anesthetic. Tiny incisions are created to insert the micro-cannulas used to suction out the fat. The results are apparent right away, but patients do have a few days of recovery time. Your problem seems relatively small and you may respond best to CoolSculpt Mini in which the fat is frozen away non-invasively.

You do have a slightly recessed chin as well, which could be improved using injectable dermal fillers. This approach allows for just enough augmentation to improve the facial contour without further deepening your mentolabial fold. The combination of CoolSculpt Mini and chin augmentation with fillers would give you the very best result.  Make sure you work with a board-certified dermatologist with expertise in these procedures to ensure the best possible result. 

The photos demonstrate a short chin in the vertical dimension. A chin implant will not be of benefit with your deep mentolabial fold. I would recommend a lengthening genioplasty with simultaneous submental and jawline liposuction. This will give you a more masculine chin and a well defined and contoured jawline. 

For a double chin, InMode FaceTite with VASERlipo would give you the best result.With significant neck sagging you would need a facelift / neck lift with muscle tightening (platysmaplasty). At the same time, I would recommend lasers (Fraxel, CO2, or Erbium) and microneedling RF (Fractora, Morpheus8, Intensif) to improve the crepey skin and wrinkles. Overall, the neck can be treated with a combination approach:
1. Microneedling and laser treatments for texture
2. Botox, Dysport, Xeomin or Jeuveau to help platysmal bands
3. Intensif, Fractora, or Morpheus8 microneedling RF for crepey skin and lifting
4. Injectable fillers like Belotero, Restylane Silk, and Juvederm Volbella to improve lines and folds
5. Face/neck lifting if sagging is prominent or premature, with or without platysmaplasty (muscle tightening)
6. Renuvion (J-Plasma), ThermiRF, and InMode FaceTite/AccuTite 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
