Long term solution for ugly lower face?

Your photographs suggests that you would benefit from a chin implant to strengthen and define your jawline.  You actually do seem to have quite a bit of submental fat, which can be removed with minimally invasive facial liposuction. Since you seem to be quite young, your skin should be elastic enough that it will need no intervention to adapt to its new shape.  A chin implant will give you a stronger yet still feminine profile. The combination of these two procedures is the easiest and most effective way of giving you a sleeker and stronger profile that harmonizes with your natural beaut
Chin implants generally last a lifetime.  Overwhelmingly, they will never have to be changed out.  However, because a patient's body changes with time and age, they sometimes decide to remove an implant or switch it out for another size. This is easy to do with silicone and that's what I recommend.
I hope this helps!

I perform regularly all kinds of genioplasties, not only sliding
genioplasties but also one, two and three-dimensional augmentation
and/or reduction genioplasties, plus other custom designs; in other
words, I know well what I am talking about.
Your case is the among the best you can meet doing chin surgery to
perform a three-dimensional osseous chin augmentation with bone supply.

That is the name of the procedure you are an optimal case for, since
you need: massive vertical augmentation, moderante anterior increase and
eventually certain grade of horizontal widening of your chin
dimensions.
This is an awesome, lifetime lasting, stable and safe procedure, which
notwithstanding needs very accurate preoperative antropometric
planning, desing, discussion and a brilliant execution, a technique full
of creativity and good aesthetic judgement requirements.
Chin implants have many disadvantages:
-visibility, static or with facial gestures / smiliing
-artificialness, fake look, evidence of implant presence

-limited lack of versatility, they do not provice vertical modifications neither reductions
-common infections
-common dislocations
-possible nerve irritation and pain
-short lifetime
So sooner than later they are normally removed, or exchanged by an osseous genioplasty.
Why
so popular (chin implants) then? Simple answer: they are technically
accessible to all surgeons, little training is required, can be done
under local and sometimes office based procedures, they are cheap.
Osseous
geniplasties are more expensive and need good skills, true, but when
performed they produce lifetime results, safe, stable overtime, very low
rate of complications, versatile three-dimensional modifications
(augmentation or reduction, vertical, horizontal and depth), low rate of
reinterventions, etc.
Feel free to request any additional information from me.

Thank you for your pictures.  In my professional opinion, fillers are not the answer at all.  At the minimum you need a sliding genioplasty to advance your chin but you may need a lower jaw surgery (sagittal split ramus osteotomy) to advance your entire lower jaw. Additionally, you may need neck liposuction.  Please visit with an orthodontist, general dentist and a board certified plastic surgeon to check out of all of your options.Best wishes

Patients have many options to improve the appearance of the lower face, neck, and jawline. Neck liposuction is probably to most common procedure, which reduces neck fat and tightens skin. For those without a chin, then some form of chin augmentation with either an implant or bone surgery would be required. Fillers are generally not considered the best option for the lower face and chin. If you haven't already, then speak with facial plastic surgeon or plastic surgeon to review possible options with you.Best,Dr. Chaboki

Thank you for your question and photos. In my opinion, I believe you would best benefit from some liposuction of the neck in conjunction with a chin implant to provide better proportion to your profile. These two procedures require a small incision below your chin and can be done under local anesthesia. These two procedures are a great duo in that they both give proportion and definition to your profile. Make sure you have a consultation with a board certified PS to be fully evaluated.

After assessing your photos, i would advise to consult with a board certified plastic surgeon. My recommendation would be: submental liposuction (fat removal using liposuction for the neck area) and chin surgery.Chin surgery, aka genioplasty or mentoplasty are procedures done to give people more appealing chins and a stronger profile.
There are two different types of chin surgery; however, implantation (mentoplasty) is the most common and sought after procedure. Chin implants can be removed if need be and are made of synthetic materials that are not only completely safe, but they also feel like a real chin when touched.
On the other hand, genioplasty is a chin augmentation surgery that does not use an implant. Instead, this procedure involves moving your bone forward to increase the projection of your chin.
