38 Yrs Old with Sudden Extreme Turkey Neck, Sagging, Thinning Neck and Lower Face. Neck Lift? (photo)

"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, Halo, or Erbium) and microneedling RF (Fractora, Morpheus8, PiXel8, 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, PiXel8, or Morpheus8 microneedling RF for crepey skin and lifting
4. Injectable fillers like Belotero, Restylane Silk, Versa, 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

Than you for your question.  If your main concern is your neck.  There is no fillers for the neck..   Botox can temporally help the banding but is temporal.  For more permanent results you might need a neck lift ant tighten the platyma band and removal of the extra skin. 

A neck lift is a general term used for rejuvenating the neckline to create a more youthful attractive appearance. Factors which are considered during your consultation to determine if you are a #candidate for #rejuvenating the neck include: •Visibility and amount of excess fat below the chin and along the neckline.•The presence of banding down the front of the #neck.•The amount of #excess skin and condition of your skin.•Chin Deficiency.•Presence of Prominent Digastric Muscles (a.k.a. submandibular gland fullness).Patients who desire facial rejuvenation that is affordable, quick, and effective should also consider the Lite-lift™. Like the Life-Style™ facelift, this is a modified facelift, individualized for each patient, that can be performed in the office with a local anesthetic and improve signs of aging around the neck, jawbone and lower face. These procedures are not "Thread-lifts" or "String-lifts". We do not use the "barbed" sutures employed in these other lifting operations. The Lite-lift™ uses longer lasting techniques that are discussed below. Because the incisions are limited, there is less bruising, swelling and healing time for most patients. Many patients can be back to work in one to two weeks looking rested and more youthful.The best candidates for #LiteLift are non-smoking patients 35-60 years old with early changes of the lower face and the neck. But whose skin has elasticity with well defined bone structure. Older patients who cannot or do not wish to have a longer operation or general anesthetic can be improved with a Lite Lift™. If you are not a candidate at the time of your #consultation, your board certified plastic surgeon can recommend non-surgical alternatives to address your concern. Consulting with a board-certified plastic surgeon who specializes in #neck lift procedures is important to ensure you are receiving the best advice, care, and surgical experience possible.

I would recommend a neck lift with platysmaplasty. Fillers will not be much help here. I would advise seeing a qualified surgeon for evaluation.

The rate of aging of the neck varies and although 38 is on the younger side, some patients will benefit from surgery at that age.  Combining the neck lift surgery with fat grafting will give optimal results
