What is the best option for my double chin and jowls? (Photos)

Unfortunately some of the minimally invasive techniques only provide excellent results with younger age patients and less skin laxity. Based on your photos I would recommend some posterior jawline liposuction and platsymaplasty, and/or platysmaplasty and a neck lift. There is a device called J plasma that can tighten the skin when done in conjunction with liposuction. However, the degree of tightening is still limited.

you likely need a nearly neck/facelift. but facetite, morpheus, threads can all be done for improvement.

if you want a dramatic change necklift/facelift, Implants and fillers will give you that. noninvasive will improve the area and facetite, threads, morpheus, and fillers can be used.  start at home dermarolling to tighten you skin, see emeragecismetics.com where we do free skincare consults daily and recommend MTS roller with anteageMD ampules daily (see dermarolling package).

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
