What is the best treatment for a sagging neck?

Without pictures or seeing you in person it is difficult to give you specific recommendations.  However, the following scenarios and procedures may be helpful.1.  Isolated vertical (up and down) bands on your neck when you grin: Botox of the bands can be very helpful.2.  Full neck, double chin: Submental liposuction or Kybella treatments may be a good option.3.  Fine lines  and slight looseness: Ultherapy and laser resurfacing, radio frequency treatment (Sublative) or chemical peel may be a good option.  4.   Loose Skin that requires you pushing back with our fingers towards your ears to simulate the results you would want: Lower facelift or neck lift is likely the best option.In any case, you would need to schedule a consultation to examine your anatomy and review the procedures which would be best for you.  

A surgical neck lift is an excellent way to look younger, as the neck is often the first thing to go. Typically patients who experience skin laxity of neck region as well as jowling of the lower face are excellent candidates for this procedure. A neck lift can leave you with a sharpened jawline, decreased jowling, and smooth skin of the neck, thus returning your youthful appearance. Commonly performed in my accredited surgical facility, I perform neck lifts where I hide the incisions in the crease behind patients’ ears. This approach allows patients to wear their hair back without anyone noticing any telltale signs of surgery. In regard to such non-surgical approaches like Ultherapy, Botox and fillers, I have found that unless you have very subtle signs of aging, the surgical approach is the most effective. Fillers can disguise "necklace lines" (the horizontal lines across the neck) and Botox can soften platysmal bands. But for a truly sagging neck, surgery is the best approach. I have also found that Ultherapy is painful for patients and the results are not impressive when compared to surgery. In addition, Ultherapy can cause internal scarring that makes future surgery more difficult. 

Thank you for your question. There are many procedures to treat a saggy neck including Ultherapy, Thermage, fillers, and permanent surgical procedures. I would advise you to
schedule a consultation with a board certified plastic surgeon for a detailed
examination to discuss all possible treatment options and what your
expectations are.
