Skin sagging 4 months after chin, jowl and neck lipo - Which procedure would help me address this?

First and foremost in order to make an assessment on the outcome of the procedure we need to see proper before and after pictures.
If you don’t have before and after pictures then ask your surgeon to forward the ones they took.
Your head position needs to maintain a consistent angle in the before and after pictures since flexing the neck changes the contour of the area.
The majority of people procedure do not have it and abnormal fat distribution.
Almost universally people seeking this procedure have a facial skeletal imbalance with a mandible that is small or lacks projection in comparison to the Maxilla.
This often presents with people having a dental occlusion overbite, profile pictures will show the upper lip having more forward projection than the lower lip. this skeletal imbalance also tends to cause a premature double chin and jowls.
When the mandible lacks sufficient forward projection the underlying platysma muscle drapes the neck in the more oblique fashion.
This is one reason why bone structure is so closely correlated with having a double chin.
In the end the contour of this part of the face is determined by a combination of a bone structure, skin, subcutaneous fat, platysma muscle, sub platysmal fat layer submandibular salivary glands etc.
Because fat is only one component and often isn’t the primary underlying cause Liposuction sometimes doesn’t have as much impact as people would expect.
Without seeing before and after pictures or doing an examination it’s hard to address if your procedure was well done or not.
It is however a complex area that is not always accurately assessed and often misunderstood.
Liposuction can in some cases give striking results. This is especially true for young people who have a good bone structure and are chubby or overweight. some people have a greater percentage of their fat in the subcutaneous layer making it more amenable to removal with Liposuction. Others have more fat deep to the platysma muscle and in those cases liposuction will be less effective.
Delivering consistent quality liposuction results including the ability to make accurate assessments and predict outcomes consistently by showing appropriate before and after pictures is more difficult than most people believe.
Finding sufficiently skills and experience providers who can first and foremost make accurate assessments and technically deliver quality consistent outcomes is not necessarily as common as people may think. The chin and neck can be a bit baffling for both patients and providers.
To get a good assessment regarding bone structure I suggest considering having a consultation with oral surgeons. oral surgeons tend to see things from a bone perspective by plastic surgeons have some overlap in the field of work but just to be more soft tissue oriented.
When considering getting a second opinion always bring in or show before and after pictures. If you don’t have them ask your sergeant to forward the ones they took.
