i have a large bulge under my chin like a frog! What are my options?

Thank you for your question and for sharing your photos. There are several options for contouring the neck.Non surgical options include: 1) Kybella to dissolve the fatty tissue in the submental area 2) Cool-mini treatment from Coolsculpting to target the same area 3)
Adding a skin tightening device such as Ulthera or Profound to the neck
tissue in conjunction with the one of the above to further tighten the
skin. Surgical options include: 1) Straight liposuction which would reduce the pinchable fat under the chin2)
Anterior neck lift with liposuction which would also allow for
tightening of the platysmal muscles in the midline to allow for tighter
neck contour3) Traditional neck lift which does the same as 2) but also removes some excess skin in the neck.I
would recommend that you visit with a board certified plastic surgeon
who offers the various options above to discuss the pros/cons of each
option and help you decide which is the best for you.

If your exam confirms that you have excess fat below your chin in the upper neck you have two main choices:Liposuction (invasive) or non-invasive: #Kybella (see below link) or possible #CoolSculpt (many say not as good).

Thanks for sharing.  From what you are describing, chin liposuction and possible laser lipolysis would likely be your option for the best results.  Exercising is helpful to lose weight but neck of facial exercise won't accomplish what you are desiring.  Consult with several experienced board certified facial plastic / plastic surgeons.
