Best procedure for me (jawline) feel like I have a double chin. (photos)

It's best to begin by consulting with a surgeon in-person to discuss your options. During your initial examination, your #chin will 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 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. Liposuction under the chin is also another option your doctor can discuss. If you are not a candidate for chin or neck rejuvenation at the time of your #consultation, your board certified plastic surgeon can recommend alternatives to address your concern. 
However, there may be additional options to improve the appearance of your concern to improve the overall balance of your face. Such can be best evaluated in-person. Consulting with a board-certified plastic surgeon who specializes in #face, #neck and #chin procedures is important to ensure you are receiving the best advice, care, and surgical experience possible.

It looks like you are a great candidate for Kybella or CoolSculpting. Both procedures are non-surgical and have limited downtime associated with them. Kybella usually takes about 10 minutes and is injected right in the office by a doctor. CoolSculpting takes about 45 minutes and is usually applied by a certified nurse. 

Thanks for your question and photos. There are a few options available that could potentially correct a double chin and define facial features. Non invasive solutions include Kybella and laser treatments, which in my opinion have less than optimal results. Surgical option would be liposculpture of the areas of concern and complimenting that with a small chin implant for a more defined jaw line and profile. Best to get an in-person consultation with a board certified plastic surgeon to discuss individual procedures that suit you.
