Best lower face procedures to correct asymmetric sagging jowls, define jawline and under chin sagging and laxity? (Photo)

It's best to begin by consulting with a surgeon in-person to discuss your options. 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. During an in-person examination, your chin will also be evaluated along with the neck and jawline. A weak #chin implies a lack of 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 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. #Liposuction is often used during or in place of a neck lift if necessary.
Also, 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. The goal is to provide a less invasive natural looking option for both men and women desiring to refresh their appearance with less downtime and risks. The LiteLift® is a “real” facelift, which does address the underlying muscle, tissue and overlying skin.
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.
A board certified plastic surgeon should evaluate both your anatomical features and aesthetic goals to suggest which procedure best suits your needs. In some cases there may be more than one option to choose from. If you are not a candidate at the time of your #consultation, your board surgeon can recommend non-surgical alternatives to address your concern.

Without an exam your question cannot be answered.  You will need to see an Oral/Maxillofacial surgeon to see if othognathic surgery, genioplasty or using an implant is best for your specific case. It should be noted that patients with severely weak jaws or abnormally functioning jaws may be better treated with other facial surgery (orthognathic surgery), although a chin augmentation may be an option at a later time. These patients should seek the advice of a plastic surgeon to determine which course is right for them. Here is some information to help you make this decision: Candidates for Chin Augmentation - Patients whose chin profiles are weak but have normally functioning jaws are candidates for Chin Augmentation. Many of these candidates have used injectable fillers in the past to strengthen the protrusion of their chins, but are looking for a permanent solution. If you are one of these patients, then you are a likely candidate for chin augmentation

I would add necklift to that list and you have presented all the options that are available to you. Jowling is best corrected with liposuction and facelift. Improving the contour of the jawline is easily accomplished with an extended facelift incision behind the ear. Fillers can help but the results are temporary.
