Is it possible to have a lower face and neck lift after Ellevate if I decide to have them in the future?

you can do face or neck lift after non invasive treatments we do it all the time! I would start sculptra and cosmelan peels at home with MTS dermarolling (see link) as this will build collagen and prepare you for face/neck lift if you need or want it.

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

There should be no problem doing a face and neck lift after Ellevate. However, why would you want to do both, especially you will probably need to do a full facelift procedure in the near future after Ellevate.
The problem is the lack of lasting results of Ellevate compared to a facelift. Also I would not consider combining the procedures at the same time. With time, there will be a difference in results and you would later want to revise the Ellevate portion.

It is not the customary threading procedure, but is more of a necklift without incisions. A more advanced form of elevate, that lifts the mid-neck underneath the chin more effectively is called a "trampoline platysmaplasty". I've performed the trampoline platysmaplasty for 11-12 years and find tht you can have any facelift or necklift procedure after, before, or simultaneously. The sutures are placed with a special blunt lighted probe through "needle punctures" that usually do not leave visible scars. The procedure can be used as a "revision" for previous necklifts. I would recommend that you see a board certified facial plastic or plastic surgeon who is trained in the advanced ellevate AND trampoline platysmaplasty.
