Any Help for Saggy Neck After Weight Loss Apart from Neck Lift with Combo Facelift? (photo)

It's difficult to determine if a non-surgical treatment will address your concern. Non-surgical treatments are an option. While they may improve the appearance of your concern, many repeated 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.During an in-person consultation, your chin will be evaluated along with the neck and jawline.The presence of banding down the front of the #neck, and, amount of excess skin and condition of your skin are among some factors which determine if you are a #candidate for #rejuvenating the neck. For individuals with signs of aging in the neck, a chin implant added to one of the recommended procedures above, will provide optimal results.
If deemed a candidate you may want to consider Lite-lift™ which is an affordable, quick, and effective innovative facelift developed by board-certified plastic surgeons Dr. Larry Nichter and myself. 
This is a modified facelift 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. 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 stable skin elasticity, well-defined bone structure but showing early changes of the lower face and the neck. Older patients who cannot or do not wish to have a longer operation or #general anesthetic can be improved with a Lite Lift™. All in all, Lite Lift™ surgery is individualized for each patient. 
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 suitable. 

I understand your hesitancy about having surgery of the face or neck at the age of 42, however the photos clearly show excess skin. This is usually a genetic trait which can be accelerated by other lifestyle factors. In my practice, I've operated on many people in their early 40's who look older than their actual age (For example: One of my patients was a 42 year old woman who had a small child and was frequently asked if she was the grandmother). This being said, you may consider a non-surgical radiofrequency-based skin tightening procedure such as Pelleve with the understanding that the results would not be the same as a surgical neck lift.
