Loose Neck Skin, What Options do I Have other than a Full Neck Lift?

A combination of non-surgical options like Kybella, PDO NovaThreads, Ultherapy and Thermage would do well in combination for skin tightening for the neck. VASER Liposuction (with ThermiRF, Renuvion and InMode FaceTite) is a great alternative for contouring and tightening the chin and neck and can be combined with a neck lift at the same time, if you're a candidate. I suggest getting a formal evaluation with a cosmetic dermatologist to develop a long-term treatment plan that works for you. Best, Dr. Emer.

It's difficult to determine if a non-surgical treatment will address your concern. Especially via online and without photos to view. Also, it really depends on the amount of #sagging you are experiencing.  If anything, non-surgical treatments may improve the appearance of your concern and many treatments may be required. A board-certified plastic surgeon should evaluate both your anatomical features and aesthetic goals to determine which option best suits your individual needs. 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).
During your consultation, your chin will be evaluated along with the neck and jawline.  A weak #chin means there is not adequate chin support for the skin along the neck line. In younger individuals a chin implant alone is usually all that is needed to improve the appearance of the neck. Subsequently, it will also improve the overall balance of the face and can create the illusion of a smaller nose. As a stand-alone procedure, chin augmentation can be performed in the office under local anesthesia. For individuals with signs of aging in the neck, a chin implant added to one of the recommended procedures above, will provide optimal results.According to your evaluation, your plastic surgeon may give you more than one option to choose from. Also, she or he can recommend non-surgical methods if you are deemed a candidate. 

It is very difficult to answer your question without seeing your pictures – you should consider posting images showing your areas of concern.  It may be that you do need a surgical face/neck lift.  As far as other options, smart lipo can sometimes tighten skin without the need for cutting skin out.
