Which procedure would help minimize the jowls and help me achieve a more defined jaw line? (photos)

You have several issues, all because of your genetics and weight loss only aggravated them:
Bulging submandibular glands, thick digastric muscle, subplatysmal fat and all together have creating the obtuse angle of your neck, lack of definition of the jawline.
So you are candidate for Deep plane neck lift in order to trim the bulging glands, trim the bulging muscle and trim the belly of the digastric muscle and tighten the platysma muscle to create a rejuvenated angled profile and sharper jawline (not masculine or exaggerated).
If you get done Morpheus, or any type of “non” invasive procedures, the scar tissues and fibrosis will ruin the possibility of a great outcome surgery.
Be encouraged!

Morpheus 8 is a non-invasive skin and soft tissue tightening treatment that is consistently amazing in our patients. We use the Morpheus to exact fractional induced RF into the skin or tissue in order to tighten collagen and stimulate contraction of the tissue. For acne scars, it is quite useful to build collagen in patients who have atrophic scars but is not very productive for ice-pick scars which require TCA Cross. For tissue tightening, Morpheus is ideal for the face and neck and we often combine it with CO2 laser or Ultherapy to further enhance results. Chemical peels and skin resurfacing should be done at least 5 to 7 days after, but can be performed earlier, depending on treatment severity. Avoid exfoliating skin treatments before Morpheus and expect a period of 2-4 weeks for skin contraction to set in.

Best,

Thank you for your question and sharing your photographs. The weight fluctuations during pregnancy have led to a combination of volume redistribution and some skin laxity. The shape under the chin suggests that there was also some volume excess prior to pregnancy related to hereditary characteristics.

The most powerful way to control the contour of the neck, which also has a lasting effect on the hereditary component of the shape, would be a deep plane neck lift. This would address both the laxity of the skin and the volume excess, predominantly in the deeper layers. Leaving behind some fatty tissue under the skin produces a good contour with a softer appearance and more youthful characteristics following the neck lift intervention.

I would recommend a facelift/necklift. This would provide the best long-term result. I recommend finding a surgeon certified by the American Board of Plastic Surgery. Ideally, one with experience in facial aesthetic surgery.

As we age, the bones in the face start to shrink and fat in the face tends to atrophy. This ultimately can result in change of the shape of the face, especially in the chin and jawline. With that said you show classic signs of excess skin, fat and fat below the muscle of the neck region, and you would benefit greatly with a deep plain NECK LIFT. The procedure takes approximately 1.5 hours to do requires 3 to 5 days of initial recovery with final results being parent as little as 4 to 6 weeks. in my experience, I would highly recommend that you do not have just liposuction alone or cool sculpting. This will not resolve your problem.

The photographs appeared to show a recessive Chin profile, and fat deposits located both above above and below the platysma muscle in your neck. A surgical neck lift can accomplish removal of both those compartments of fat, in addition to a plasma plasty to significantly improve the jawline. Liposuction alone can only remove the fat deposits above the plasma muscle, which will not be very effective for you. When patients have a recessive chin profile, consider placement of a chin implant to augment the chin forward, which also helps your jawline profile. Both procedures can be done together or separately.

Facial aesthetics are primarily determined by facial, skeletal structure.
Issues related to the lower 1/3 of the face and neck are primarily determined by the shape and size of the mandible.
Individuals who have a weak mandible are prone to develop loss of jawline, definition, a double chin And premature jowls.
Age also contributes. Bone structure will determine if people will develop premature signs of aging or hold aesthetic youthful looks into later life.
Liposuction may offer subtle improvements.
Growing a bigger mandible is probably not realistic.
I think most plastic surgeons would probably lean towards a neck lift as the appropriate best procedure.
And neck lift typically includes removing subcutaneous fat.
A neck lift will address skin, subcutaneous, fat, and laxity in the platysma muscle.
This area is fairly complex, and there are many variables.
Treating the primary underlying cause tends to be difficult so often treatment suggestions are going to be aimed at soft tissue solutions.
I suggest having multiple in person consultations with plastic surgeons in your community.
Expect providers to have different opinions.
This is often the case when there is no single best treatment option.
Good luck,
