Fillers to fix double chin? (Photo)

Kybella has a great track record in reducing fat beneath the chin. Your goal is to get rid of the fat and Kybella (or possibly CoolSculpting) could be ways to achieve that goal.
See a dermatologist who offers both options.

A front face view to see your cheeks and a profile view of the other side of your face would be helpful. I quite agree to stay clear at this time of more invasive procedures, such as liposuction or even of a series of Kybella injections, that, too, typically have a significant swelling downtime after each treatment session. The problem doesn't seem severe enough to warrant aggressive treatments. If there is any volume loss in the cheeks that is contributing to sagging below--which cannot be assessed from the photos provided--this can be addressed easily with a volumizing filler. Likewise, a filler can help to straighten and better define the jawline. Make sure that you consult with a board certified aesthetic physician and ask to see his/her personal before and after photos before agreeing to proceed. And, finally, exercise a good deal of "buyer beware" caution when evaluating claims for this or that relatively expensive fraxel laser, radiofrequency or ultrasound treatments. Best of luck.

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

See an expert for a formal evaluation and to develop a personalized treatment plan based on your individual situation and goals.

It is difficult to assess without pictures of your chin. But commonly, you can do CoolSculpting if you fit the applicator, or Kybella to dissolve the fat. Please contact a qualified provider or a board-certified physician with extensive experience in these procedures.
